Chapter 2.4, "Mounting a module", on page 41.
1.1.6 Safety considerations for SSRs
Risk of injury and damage due to inappropriate SSR usage
At power loss, solid-state relays (SSRs) have no defined switching state. Hence, other
than an electromechanical monostable relay, if there is a malfunction (for example,
missing supply voltage), typically the SSR ports go to a high-impedance state. But the
relay does not actively switch off a connected load. This failure can lead to a risk of
personal injury and damage of equipment.
To prevent this risk, you must implement a dedicated concept for failsafe operation of
your system in a competent manner.
Welcome
Safety and regulatory information
Risk of damage due to inappropriate SSR usage
Solid-state relays (SSRs) are intended for high-frequency and high-speed switching,
but their semiconductor elements are damaged easily by excess current, voltage
peaks or a short circuit. Hence, inappropriate conditions or usage can damage SSRs
or connected components and lead to associated problems.
To prevent this risk, avoid excess current, voltage peaks and short circuits.
Risk of SSR damage due to inappropriate operating conditions
Solid-state relays (SSRs) for RF applications are intended for switching low powers. To
avoid damage due to overload, refer to the operating conditions according to the data
sheet.
Monostable vs. failsafe
Without power, a solid-state relay (SSR) quits operating as a switch:
●
It is in a non-defined high-impedance state
●
It does not have any stable switching state
Sometimes, SSRs are considered as behaving like a monostable relay. And the term
"monostable relay" is often considered to be equivalent with the term "failsafe relay".
However, this interpretation is misleading.
See also "Monostable and bistable relays" on page 53.
See also "FS (open)*" on page 53.
See also "Off/on switching states of various relays" on page 330.

2.1.6 Considerations for test setups
Preventing electrostatic discharge (ESD)
Electrostatic discharge is most likely to occur when you connect or disconnect a DUT.
NOTICE! Electrostatic discharge can damage the electronic components of the
►
product and the device under test (DUT).
Ground yourself to prevent electrostatic discharge damage:
0025.2365.00
0086.4400.44
a) Use a wrist strap and cord to connect yourself to ground.
b) Use a conductive floor mat and heel strap combination.
A risk of damage due to ESD is typically limited to switch units that are equipped with
modules that have one or more of the following features:
●
Digital input or output ports (I/O ports)
●
Solid-state relays (SSR)
●
Integrated amplifiers in special modules that are delivered as part of a test system
Preventing electromagnetic interference (EMI)
Electromagnetic interference (EMI) can affect the measurement results.
To suppress electromagnetic radiation during operation:
●
Use high-quality shielded cables, for example, double-shielded RF, LAN and HDMI
cables.
Note: USB cables are of varying and often poor quality. Therefore, consider the
quality of each individual USB cable.
●
Always terminate open cable ends.
●
Note the EMC classification in the data sheet.
●
Ensure that connected external devices comply with EMC regulations.

R&S®OSP
Getting started
Preparing for use
Preventing overload on internal terminations
Overloading an electromechanical RF relay with internal port termination can damage
or destroy the relay.
The maximum load that the internal termination of one port can handle is approximately 1 W. However, if the relay has several terminated ports, their cumulative maximum load is less than the sum. For example, an SP6T relay with 6 internally terminated ports cannot handle 6 W, but typically 3 W, only.
To avoid the risk of damage due to overloading internal terminations, limit the load to
the "Max. termination power per relay" that is specified in the data sheet.
2.1.7 Connecting to power
The switch unit is equipped with an AC power supply connector and can be used with
different AC voltages. The R&S OSP adapts itself automatically to the voltage. Refer to
the data sheet for the voltage and frequency requirements. The AC power connector is
on the rear panel of the switch unit.
► Connect the R&S OSP to an AC power supply using the supplied power cable.
As the switch unit's assembly is in line with the specifications for safety class
EN61010, you must connect it only to an outlet that has a ground contact.
For replacing the fuses, refer to Chapter 12.1, "Replacing fuses", on page 315.
2.1.8 Connecting to LAN
The LAN connector (RJ45) of the R&S OSP is on its rear panel, shown in Figure 2-16.
Network environment
Before connecting the product to a local area network (LAN), consider the following:
●
Install the latest firmware to reduce security risks. See Chapter 12.3, "Firmware
update", on page 317.
●
For internet or remote access, use secured connections if applicable.
For example, use HTTPS, SFTP, FTPS instead of HTTP, FTP.
●
Ensure that the network settings comply with the security policies of your company.
Contact your local system administrator or IT department before connecting your
product to your company LAN.
●
When connected to the LAN, the product may potentially be accessed from the
internet, which may be a security risk. For example, attackers might misuse or
damage the product.
For more information on how to connect the switch unit to the LAN, and for the IP
address, see Chapter 4.3, "LAN connection", on page 151.

2.1.10 Connecting RF cables
Getting started
Preparing for use
2.1.9 Connecting monitor, mouse and keyboard
The HDMI and USB connectors for an external monitor, a mouse and a keyboard are
on the front panel of the R&S OSP, shown in Figure 2-16.
For connecting these devices, see Chapter 4.2, "Instrument control", on page 150.
Many modules are desigened for connecting test equipment via RF cables.
Excessive tightening of coaxial RF connections can damage the connectors of both
cables and modules. Too weak tightening leads to inaccurate measurement results.
Connecting RF cables / TORQUE RECOMMENDATIONS
For best connections, proceed as follows:
1. Carefully align the connectors along a common axis.
2. Mate the connectors along the common axis until the male pin of the inner connector engages with the female socket of the outer connector.
3. When fastening the connectors, only turn the nut of the outer connector until the
connectors are firmly coupled.
Avoid rotating the body of the outer connector.
4. If the inner connector is on a cable, hold it stationary with a spanner.
5. For fastening the connection, use a calibrated torque wrench suitable for the connector type.
Never use a standard open-end wrench.
6. Fasten the nut of the outer connector to the specified torque.
For specifications, refer to application note 1MA99, which is available on the
Internet at www.rohde-schwarz.com.
For N, SMA and PC connectors, we recommend applying the following torque:
● 150 N·cm for N connectors
● 56 N·cm for SMA connectors (standard, PTFE-filled)
● 90 N·cm for PC connectors (3.5 mm / 2.92 mm / 2.4 mm / 1.85 mm, air-filled)
Rohde & Schwarz offers torque wrenches for various connectors. For ordering
information, also refer to the application note 1MA99
7. Note that 3.5 & 2.92 mm PC connectors are incompatible with 2.4 & 1.85 mm PC
connectors.
2.1.11 Connecting control cables
Many modules are desigened for connecting test equipment via control cables. Typically, these connections are straight forward and require no precautions.

2.1.12 Switching on or off
Getting started
Preparing for use
However, take special care in the following cases:
●
In I/O modules (input / output), avoid overloading the digital input lines. The maximum voltage to be applied directly to the input connectors is TTL level: standard
3.3 V DC, tolerating up to 5 V DC. For voltages > 5 V DC up to 28 V DC, insert a
resistor in series with a minimum resistance of 22 kΩ.
●
In the satellite system, use the [Wired Link] connectors only for connecting the
remote control module R&S OSP-B200R with the satellite unit R&S OSP-B200S2.
Connecting a [Wired Link] connector to any other device's connector can damage
your equipment.
See Chapter 2.2.2.4, "Rear panel of the R&S OSP-B200S2 satellite unit",
on page 31, and Chapter 3.57, "R&S OSP-B200R remote control module",

Getting started
Preparing for use
To disconnect from power
1. Shut down the switch unit.
2. Disconnect it from the power source.
How to avoid losing settings
While the R&S OSP is in operating mode, if you switch it off using the rear panel switch
or by disconnecting the power cord, the instrument loses its current settings. (Operating mode is indicated by a green LED above the [Pwr] key.)
For example, if you have selected signal paths previously, you must select and enable
these paths again, when you restart the switch unit.
To avoid a loss of settings, press the [Pwr] key first to set the switch unit into standby
mode. Then shut it down properly by setting the rear AC power switch to position [O].
●
If "Configuration" > "General" > "Switch-On Reset" is activated, the R&S OSP
resets all internal latching switches during the startup procedure.
●
If "Configuration" > "General" > "Switch-On Action" is set to "Switch Path", the
R&S OSP loads the previously set path while booting. The switch unit activates this
path when the startup procedure is completed.
Display timeout
The OLED status display of a switch unit R&S OSP220 or R&S OSP320 serves for
showing you the network connection. The LAN connection is set typically at power-up.
The status display switches off automatically after setting the LAN connection with a
timeout specified by the Status Display Period. Without a network connection, the status display switches off with the same timeout after power-up. This feature helps to
prevent burn-in effects often seen in OLED displays.
When the switch unit is connected via a new network address, the status display is
switched on again for the next 30 minutes. (Your server can assign a new address, for
example, when you change the switch unit's network settings from static IP to DHCP.)
The RGB-LED touchscreen display in the R&S OSP230 and in the module
R&S OSP-B300M needs no burn-in protection. Thus, it has no timeout.
2.1.13 Checking the installed modules
The instrument is typically equipped with one or more optional switch modules.
You can visually check whether the modules listed on your delivery note correspond
with the installed modules. Each module's name is printed on its panel.
You can also view the installed modules in the "Module Operation" dialog (touchscreen
display or "WebGUI", see Chapter 2.3.2, "User interface and functional elements",
on page 34):

Figure 2-2: The module operation dialog, here with a single switch unit and 5 modules
The information in this dialog is updated during the booting process, when the
R&S OSP automatically scans all its installed modules. The switch unit stores the information on these modules in its internal flash memory (SD card).
If you have mounted additional modules or removed original ones, the switch unit
detects and stores this changed configuration of modules. If Module Check is enabled,
the R&S OSP automatically prompts you with information on the changed modules.
If the Virtual Mode is enabled, you can edit the list of frames (switch units) and their
modules.
To check the installed options from a remote computer in the same local area network
as the R&S OSP, you can use the remote control command ROUTe:MODule:
CATalog? on page 305.
2.1.14 Configuring the initial instrument settings
After startup, the switch unit is fully configured automatically, and ready for use.
However, you have many options to change the configuration, for example:
●
Edit the network settings, see Chapter 5.4.3, "Network", on page 217
●
Define or modify a setup of primary and secondary switch units, see Chapter 5.4.4,
"Interconnection", on page 220
●
Restore a previous setting, see "Backup/Restore" on page 223

2.3.1.2 Manual remote operation
Getting started
Trying out the switch unit
You can control one or more switch units by working with the user interface in a web
browser ("WebGUI") on a remote computer that is connected via LAN. Refer to Chap-
ter 4, "Operation", on page 149.
Figure 2-14: Manual remote operation via "WebGUI" and LAN
RJ45 = Ethernet (LAN) connector on the rear panel of each switch unit
For interconnecting several switch units, see Chapter 4.5, "Operation in interconnec-
tion mode", on page 154.
Note that the legacy software R&S OSP Panel is not compatible with the switch units
R&S OSP220, R&S OSP230 and R&S OSP320.
2.3.1.3 Remote operation by SCPI commands
You can control the R&S OSP by SCPI commands sent from a remote computer that is
connected via LAN. Refer to Chapter 4, "Operation", on page 149.
Figure 2-15: Remote operation by SCPI commands
RJ45 = Ethernet (LAN) connector on the rear panel of each switch unit
Far left = Two switch units integrated in a test system like R&S CEMS
To do so, you have the following options:
●
For SCPI command communication, use a terminal program like R&S Forum or
similar programming interface (for example with R&S VISA driver), see Chapter 7,
"Remote operation", on page 248. For remote control commands, refer to Chapter 8, "RC commands", on page 254.
●
Use your own application to communicate with the R&S OSP via a VISA interface
or directly via a TCP/IP raw socket connection.
●
Let a test system software like R&S EMC32 or R&S ELEKTRA send the required
commands.
The R&S OSP can handle up to 5 open SCPI command connections simultaneously.

2.3.2 User interface and functional elements
The switch units R&S OSP220 and R&S OSP320
The switch unit R&S OSP230 and the display
module R&S OSP-B300M have a touchscreen
display.
For a description of the functions of this interface,
refer to Chapter 5, "Functions", on page 159.
When you switch on an R&S OSP220 or R&S OSP320 with status display, it originally
shows the following information, before the device is operational:
●
1st line: device type, for example "OSP320"
●
2nd line: firmware version, for example "FW Ver. 2.0"
●
3rd line:
– Before the switch unit scans for modules:
FPGA version, for example "FPGA Ver. 7.1 A"
– After scanning for modules begins:
MAC address, for example "00:E0:33:04:C7:25"
●
4th line: "Booting...", then "Scanning Mxx..."
have a status display.
For a description of the information shown in the sta-
tus display, see below.
See also "Display timeout" on page 23.
Getting started
Trying out the switch unit
After booting and scanning, the status display shows the following information:
●
1st line: hostname or "Hostname N/A"
●
2nd line: IP address or "Address N/A" or "Auto-DHCP" (if Auto-DHCP is enabled,
but the switch unit is "Disconnected")
●
3rd line: subnet mask or "Mask N/A"
●
4th line: device status information
Not all applicable device status information may fit into the 4th line. Therefore, this line
shows only the 1 most relevant information from up to 2 of the following groups in an
order of relevance as listed here:
●
Connection mode information:
– "SEC" (secondary device in an Interconnection setup)
– "LLO" (remotely controlled with local lock-out)
– "Remote" (without LLO)
– "PRIM" (primary device in an Interconnection setup)
– "Disconnected" (which also implies "Single" state)
If the switch unit is in none of these modes, it is in "Single" mode (which is not dis-
played).
●
"Device messages" (see Figure 5-4):
34User Manual 1178.7100.02 ─ 07

Trying out the switch unit
– Errors
– Warnings
If no errors and no warnings are available, no device message is displayed.
●
Additional information:
– "Trigger"
– "Locked"
If the switch unit is not triggered and not locked, no additional information is dis-
played. Also, if both a connection message and a device message are shown
already, additional information (which has lower relevance) is skipped due to a lack
of space.
●
Connection state information:
If none of the above is valid, the 4th line of the status display shows one of the following states of the switch unit:
– "Auto DHCP" (which also implies "Single" state)
– "Static IP" (which also implies "Single" state)
– "Disconnected"
During shutdown, the status display displays "Terminating...".
You cannot operate the switch units R&S OSP220 ‒ and the R&S OSP320 without display module R&S OSP-B300M ‒ by their status displays. To operate these switch units
without the graphical user interface of a built-in full touchscreen display, use one of the
following alternatives:
●
As on the right-hand side in Figure 2-13, connect an external monitor to the HDMI
connector on the unit's front panel (labeled 5 in Figure 2-16). Also connect a
mouse and keyboard to the USB connectors, labeled (4).
●
Use the switch unit as a secondary device in interconnection mode, as described in
Chapter 4.5, "Operation in interconnection mode", on page 154.
●
Connect the switch unit to a local area network (LAN) by the RJ45 connector on
the unit's rear panel. The connector is labeled (1) in Figure 2-16. Read the unit's IP
address from the status display and proceed as described in Chapter 2.3.1.2,
"Manual remote operation", on page 33, or Chapter 2.3.1.3, "Remote operation by
SCPI commands", on page 33.

resolution of 800 x 480 pixels. Incompatible monitors cannot display the graphical user
interface.
With the trigger connectors (6), the R&S OSP is prepared for external triggering,
which requires the hardware trigger option R&S OSP-K100. Firmware versions below
version 2.00 do not support this trigger option.
Note that the rear interface panel of the R&S OSP320 has an additional D-Sub 9 trigger connector, as shown in Figure 2-11.
In any of these configurations, you can operate a switch unit by its user interface:
either on an external monitor or in a web browser (we recommend using Chrome as
browser). The same holds true for the R&S OSP230 and R&S OSP320 with integrated
display module R&S OSP-B300M, which allow touchscreen operation.
Using any of these options, you get access to the graphical user interface (GUI):

Sometimes, the representation at the size of the touchscreen display differs significantly from the representation at full-screen size. For example, the system module
R&S OSP-B157WX (which is not described in this user manual) has a touchscreen
representation (left in Figure 2-22) that is merely large enough to allow operating the
switches. However, the full-screen representation (right in Figure 2-22) also shows the
interconnections among the switches:

2.4 Mounting a module
If you have ordered your R&S OSP together with switch modules, these modules are
already factory-mounted in the base unit and tested by the manufacturer.
41User Manual 1178.7100.02 ─ 07
R&S®OSP
Getting started
Mounting a module
However, you can order and mount additional modules.
Limitations in module mounting
Before you order a module, refer to Table 2-4 and to Table 3-1, and consult with
Rohde & Schwarz sales representatives for possible configurations.
The modules R&S OSP-B104 and R&S OSP-B106 must be mounted by
Rohde & Schwarz service personnel, as mounting these items requires opening the
switch unit's casing. If you try to mount the feedthroughs R&S OSP-B011/R&S OSPB012, but you cannot cannot feed the cables through the switch unit's casing without
opening it, let Rohde & Schwarz service personnel mount the feedthroughs.
The display module R&S OSP-B300M can be mounted into the R&S OSP320 only by
the manufacturer and only into the front panel.
If you mount the R&S OSP-B200R for controlling any modules remotely that require
two control cables, you must connect the remote control module to two flat-ribbon control cables. If available, use the control cable of a neighboring slot. If no flat-ribbon control cable of a neighboring slot is available, contact Rohde & Schwarz service for
mounting it with a second control cable connected to an additional connector on the
motherboard.
Never open a switch unit
If opening is required for mounting a module into the switch unit (see Table 2-4), let
Rohde & Schwarz service personnel mount this module.
Risk of injury during module mounting
You can mount modules that do not require opening the switch unit. However, mounting a module requires removing at least one blank plate or a previously mounted module, which partly opens the switch unit's casing. The electrical connection required for a
new module is via one or two low-voltage flat-ribbon module bus cables, which are
easy to reach.
Observe the following:
●
Before mounting a module, disconnect the switch unit from power.
●
Adhere to the step-by-step instructions for module mounting.
●
Do not use pointed or sharp tools, which can damage internal components or
cables, especially their isolation. Any such damage can lead to a short and to
accessible life components inside the switch unit.
●
Avoid touching possibly life components, which can lead to electric shock.
●
Avoid touching any exposed sharp edges or points inside the switch unit, which
can lead to personal injury, especially cuts in your fingers. Consider wearing protective gloves, especially when you take module bus cables out of their clamps
behind the slot opening (see step 7 on page 44).
●
Avoid interacting with the switch unit's interior in an unintended way, which can
lead to unpredictable situations.
●
If you drop a metal screw or a similar electrically conductive item into the switch
unit, do not turn it on before removing the item, to avoid a short.
42User Manual 1178.7100.02 ─ 07
R&S®OSP
Getting started
Mounting a module
Automatic module recognition
Whether a module is mounted by the manufacturer or by you, the switch unit automatic
recognizes the module type, as described in Chapter 2.1.13, "Checking the installed
modules", on page 23.
Module dimensions
The various modules occupy a width of 1, 2 or 3 slots in a 2-HU switch unit.
●
The size of a one-slot module's panel (H x W) is 65.5 mm x 107.6 mm
●
The size of a two-slot (double-width) module's panel is 65.5 mm x 216.2 mm
●
The size of a three-slot (triple-width) module's panel is 65.5 mm x 324.8 mm
The depth of the modules is given as "Dimension (D)" in the data sheet. Most modules
are 54 mm to 88 mm deep.
Deep modules
The following standard modules are significantly deeper than the others:
●
The R&S OSP-B104 has a depth of 265 mm
●
The R&S OSP-B106 has a depth of 152 mm
●
The R&S OSP-PM-I has a depth of approximately 200 mm (with cable loop)
The module R&S OSP-B104 occupies more than half of the depth of the switch unit.
Therefore, in a slot opposite of it (front versus rear), you cannot install another
R&S OSP-B104 or a R&S OSP-PM-I into the same switch unit. Anyway, the module
R&S OSP-B104 must be mounted by Rohde & Schwarz service. If you mount the module R&S OSP-PM-I, mount it opposite of a shorter module or opposite of a blank plate.
You cannot mount any deep module into a satellite switch unit R&S OSP-B200S2, as
this unit is not deep enough. Also, you cannot mount any three-slot (triple-width) modules into a satellite switch unit. Mounting RF feedthrough panels R&S OSP-B011 or
R&S OSP-B012 into a satellite switch unit makes no sense.
To mount a module into a switch unit
WARNING! The following procedure requires partly opening the switch unit's cas-
1.
ing. Doing so while the power is on can lead to electric shock. See "Risk of injury
during module mounting" on page 42.
Before mounting a module:
a) Shut down the switch unit, see "To shut down the R&S OSP" on page 22.
b) Set the power switch to position [0] (Figure 2-16).
c) Disconnect the power cable.
2. Optionally disconnect all other cables, too.
3. Select a slot, ideally covered by a blank plate, for mounting the new module on the
front or rear side of the switch unit.
If no blank plate is available, consider removing an existing module, instead.

unit, which can lead to personal injury, especially cuts in your fingers. Consider
wearing protective gloves.
Find a flat-ribbon cable (module bus cable) in the open slot of the switch unit.
8. If a clamp fixes the flat-ribbon cable, remove the cable from the clamp.
NOTICE! Avoid bad contact with open cable ends. The 26-pin flat-ribbon cable
9.
(module bus cable) has open cable ends, which can be live with up to 28 V DC. If
the cable ends contact any conductive parts, for example a switch unit's casing,
this short connection can cause damage in the switch unit's electronic components.
Avoid any contact of the cable ends with conductive parts.
● Fix each unused flat-ribbon cable by its clamp (labeled 5 in Figure 2-25).
● When clamped, ensure that the open cable ends point away from the casing.
● If an accidential short contact happens and leads to device damage or malfunction, call Rohde & Schwarz service.
NOTICE! Avoid bad connector mating. Each module is connected to the switch unit
10.
by one or two 26-pin flat-ribbon cables (up to 28 V DC, Figure 2-24). The connector
shape serves as protection against reversed (180° rotated) connector mating.
Nevertheless, if you use increased force, you can mate the flat-ribbon cable's connector in reversed orientation. This bad connection can damage the electronic
components of the switch unit and the module. It can damage also the connector
pins.
44User Manual 1178.7100.02 ─ 07
R&S®OSP
Getting started
Mounting a module
To avoid this risk, always mate the connector in the correct orientation, with moderate force. Do not rotate or tilt the connector.
Connect the flat-ribbon cable to your module’s connector.
Figure 2-24: To attach or release the cable, press the latches on the sides of its connector
11. If you mount a module that has connectors for 2 control cables, connect the module to 2 neighboring flat-ribbon cables of the base unit.
Adhere to the following rules:
● Do not cross-over two flat-ribbon cables (see also the example at the end of
the description of DIAGnostic:SERVice:HWINfo?)
● If you mount a three-slot (triple-width) module, do not skip the flat-ribbon cable
of the middle slot
● If you must connect 2 module bus cables (flat-ribbon cables) to a module, con-
nect the cable with the lowest name value (e.g., [M01], see Figure 2-26) to the
module's bus connector with the lowest number (e.g., [X100]). Then connect
the second cable [M02] to [X101].
● If you mount the one-slot module R&S OSP-B200R, which requires connecting
2 flat-ribbon module bus cables, we recommend mounting this module in the
slot associated to the cable with the highest name value.
For example, in an R&S OSP220, mount it in slot [FS03], which has a module
bus cable connected to module bus connector [M08] on the motherboard (see
Figure 2-26). If your application requires connecting 2 module bus cables, use
the cable of a neighboring slot (for example [M07] in slot [FS02]) as the additional cable. Connect this cable to connector [X100] on the module, and connect [M08] to [X101].
If necessary, you can use 2 non-neighboring cables for the R&S OSP-B200R. If
no cable of a neighboring slot is available, let Rohde & Schwarz service mount
this module.

Special issues with the 3-HU switch unit R&S OSP320:
● If you insert a module into the switch unit R&S OSP320, insert the module rota-
ted counterclockwise by 90°. Hence, if you face the panel of the module that
you mount, rotate it to the left.
● Note that you can mount only one-slot modules (panel size 65.5 mm x
107.6 mm) into the R&S OSP320.
13. Fix the inserted module with the six original screws (or more screws, if you mount a
larger module).
14. Reconnect the switch unit (see step 1 and step 2).
15. Switch on the switch unit.
During start-up, all modules automatically register in the switch unit. You do not
have to interact with this process. No manual registration or testing is required.
The switch unit and its mounted modules are ready for use.

Getting started
Mounting a module
Both the R&S OSP220 and the R&S OSP230 are equipped inside with 6 module bus
cables (flat-ribbon cables), hence, one per module slot (disregarding the touchscreen
display of the R&S OSP220). The R&S OSP320 is equipped with 10 module bus
cables.
When you open a blind plate or remove an existing module, you get easy access to
one module bus cable per slot.
The motherboard, which is identical in all switch units, has 16 module bus connectors,
labeled M01 to M16. In the standard configuration of all switch units, either 6 or 10 of
the connectors (as stated above) are equipped with module bus cables:
Figure 2-26: Top view of the motherboard with its connectors for module bus cables
RS = Rear slots RS01, RS02, etc.
FS = Front slots FS01, FS02, etc.
OSP2x0 = 6 slots in the R&S OSP220, 5 slots in the R&S OSP230
OSP320 = 10 slots in the R&S OSP320
M01 - M10 = Numbers of the module bus cables = Labels of the module bus connectors on the motherboard
(M11 - M16: unused)
Hence, the R&S OSP220 with 6 slots and the R&S OSP230 with 5 slots both have 6
module bus cables, connected to M01 - M03 and M06 - M08.
The R&S OSP320 with 10 slots has 10 module bus cables, connected to M01 - M10.
For more details, see also Chapter B, "Motherboard interfaces", on page 328.

Getting started
Mounting a module
The software uses M01, M02, etc. instead of RS01, RS02, etc., as it cannot detect a
module's mounting position. It detects only to the module bus connector on the motherboard, to which a module is connected.
Hence, a module information dialog addresses a module by its module bus connector,
for example, "Module Connector: M01".
In a factory configuration, the correlation of slot positions and module bus connectors
follows the scheme in Figure 2-26. If you mount modules yourself, we recommend that
you adhere to the same correlation.
The positions of the front and rear slots in the different switch unit models are also
shown in Chapter 2.2.1, "Front panel view", on page 25, and Chapter 2.2.2, "Rear
panel view", on page 29.

Modules
For connecting modules, see Chapter 2.1.10, "Connecting RF cables", on page 21,
and Chapter 2.1.11, "Connecting control cables", on page 21.
There are modules with electromechanical relays and with solid-state relays (SSRs) of
the types SPDT, DPDT and SPxT. Also, some modules feature input and output channels, multiplexers or attenuators. For details of the modules, refer to the subchapters
linked from the table above. See also the data sheet and the product brochure of the
R&S OSP.
For system modules R&S OSP-B15x(x) and R&S OSP-BSxx(x) (not included in this
manual), refer to the individual user manuals of these modules and to the data sheets
of the test systems.
For the dimensions and installation of modules in a base unit, see Chapter 2.4, "Mount-
ing a module", on page 41, and Chapter 2.4.1, "Module integration overview",
on page 46.
For information on the base units, see Chapter 2.2, "Instrument tour", on page 25.
FS (open)*
If there is a (partial or full) system blackout, a monostable (failsafe, non-latching) electromechanical SPDT switch opens the connection between C (common port) and NO
(normally open port). It goes to its default state of connecting C with NC (normally
closed port). Similarly, a monostable (failsafe, non-latching) electromechanical DPDT
switch goes to its default connection pattern, typically connecting ports 1+2 and 3+4.
But a monostable (failsafe, non-latching) electromechanical SPxT switch connects C to
no terminal at all. This behavior is called "failsafe (open)" (or "FS (open)" or "FS-o" for
short). Solid-state relays (SSRs) have no defined state at power loss, see Safety con-
siderations for SSRs.
Monostable and bistable relays
Electromechanical relays can be a monostable or a bistable type:
●
A monostable electromechanical relay has two or more switching states, of which
only one is stable. The relay remains in this stable state (default state), unless it is
activated, typically by a control voltage. When the control voltage or even the supply voltage is cut, the relay automatically returns to its default state.
Monostable electromechanical RF relays are called "failsafe", because at power
loss the switches automatically return to their disabled (safe) state:
– An SPDT relay opens the connection from C (common) to the NO (normally
open) port and closes the connection from C to NC (normally closed)
– An SPxT relay opens the connection from C to all ports, see also FS (open)*
– A DPDT relay switches all ports to their default connection pattern
●
A bistable electromechanical relay (SPDT or DPDT) has two switching states, of
which both are stable, even when there is no power.
The same holds true for multistable electromechanical SPxT relays: one stable
state is with all ports open (reset), the other states are with C connected to one of
the ports.
Switching a bistable or multistable relay from one state to the other or back always
requires an input of energy.
53User Manual 1178.7100.02 ─ 07
R&S®OSP
Modules
Manufacturing an electromechanical relay of this type is more complex and hence
more expensive than a monostable electromechanical relay. However, operating a
bistable or multistable electromechanical relay can be significantly more economic,
because it does not consume electrical power between the switching procedures.
Bistable electromechanical RF relays are called "latching", because the switching
state persists, if without power.
Both monostable and bistable electromechanical relays have their own drawbacks and
advantages, which you must observe for reaching a defined switching state at power
failure. Disregarding these relay properties can lead to undefined and possibly dangerous situations, for example human exposure to amplified RF radiation in a test system.
It is in your responsibility to avoid such situations. We recommend that you safely
avoid any possibly dangerous situation by the design of your system, in which you use
the relays.
Solid-state relays (SSR) are sometimes considered monostable, too, but SSRs are
not "failsafe".
Refer also to Chapter C, "Off/on switching states of various relays", on page 330.
Terminated vs. non-terminated ports
Terminating a non-activated RF port with a load of matched impedance (here: 50 Ω)
avoids reflection of RF power and hence avoids possible detrimental effects on system
performance.
The ports of electromechanical RF relays can have internal or external termination.
See also "Preventing overload on internal terminations" on page 20.
Termination in SSRs:
●
In an SSR, terminated ports are called "absorptive" or "absorbing".
In contrast, the following SSR ports are called "reflective":
●
Open (non-activated) ports
– With a short to ground
– With a non-matched termination
– Without termination
●
Ports with a non-matched external termination
For information on modules with port termination, refer to the R&S OSP data sheet.
The R&S OSP can supply a maximum current of 800 mA at 28 V DC per module bus
cable to the modules. The maximum total current for all slots in the switch unit is 10 A.
For module data and base unit data, refer to the data sheet.

Naming conventions
To help identify frequency ranges and functions, R&S OSP switches use suffixes to
show the following:
●
Function: "L" denotes a "latching" (bistable or multistable) relay, the current state
of the relay does not change if power is switched off. In contrast, monostable relays
switch back to their initial state in the absence of a control voltage, and are not
denoted with a suffix. A monostable electromechanical (non-SSR) relay does so
even without any voltage applied, which is called failsafe behavior.
●
Frequency: The suffixes "E", "H", "U" and "V" (as in R&S OSP-B125E, for exam-
ple) stand for increasing maximum frequencies above 18 GHz.
●
Termination of relay ports (reflective vs. absorptive behavior) is not denoted with a
suffix.
●
Relay names: On most module panels, the relays are labeled with names such as
"K11" or "K2".

3.1.1 Mounting the R&S OSP-B011 and R&S OSP-B012
You can mount feedthrough panels in any module slot of each switch unit.
Typically, two feedthrough panels are used to feed cables through from the front to the
rear of a rack-mounted switch unit.
In this setup, avoid mounting the feedthrough panels with a lateral offset of more than
1 slot position. Hence, do not feed cables through from front left-hand slot to the rear
right-hand slot, or vice versa.
Mounting procedure
To mount a combination of 2 feedthrough panels and one or more cable sets from
Table 3-2 into a switch unit, proceed as follows:
1. Turn off the switch unit.
2. Unplug the power supply cable from the switch unit.
3. Select a front and rear slot, ideally covered by a blank plate, for mounting the feedthrough panels.
If no blank plates are available, consider removing existing modules, instead.

4. Remove an existing blank plate or single-slot module from the front of the switch
unit, keeping the 6 screws.
5. Remove an existing blank plate or single-slot module from the rear of the switch
unit, keeping the 6 screws.
Note: Avoid feedthrough setups with a lateral offset of more than 1 slot position.
If you remove a module that is more than 1 slot wide, close the excess slots with
blank plates.
6.
Remove the lock nuts from all cable ends that go into the 1st feedthrough panel.
7. Insert the connectors into the feedthrough panel's holes from the rear side.
8. Make sure that the machined flats of the connectors meet with their counterpart in
the panel hole.
9. Fix the connectors with their lock nuts, using a standard open-end wrench.
10. Insert the cables into one open module slot.
11. From there, feed the cables through the switch unit to the other open module slot.
If you cannot feed the cables through the switch unit's casing without opening it,
quit or revert this procedure and let Rohde & Schwarz service personnel mount the
feedthroughs.
12. Remove the lock nuts from these cable ends.
13. Make sure not to have the cables twisted.
14.
Insert the connectors into the 2nd feedthrough panel's holes from the rear side.
15. Make sure that the machined flats of the connectors meet with their counterpart in
the panel hole.
Note: The flats in the opposite feedthrough panels help you to fix the cables in a
non-twisted position.
16. Fix the connectors with their lock nuts.
17. Fix both feedthrough panels with the screws that you kept in step 4 and step 5.
18. Reconnect the switch unit to power.
19. Switch on the switch unit.
The switch unit is ready for use.

The relay type is monostable (or "failsafe open"). Hence, with no voltage applied to the
relay, no RF connection is provided from terminal C to any of the numbered ports. To
establish an RF connection between C and one of the numbered ports, a continuous
voltage must be applied to the corresponding power terminal of the relay.
The relay is mounted directly into the module's panel and soldered to the module's

The digital input/output one-slot module R&S OSP-B103 (order no. 1505.5301.02) consists of a 16-bit input port and a 16-bit output port, controlled by a logic interface.
See also Chapter 6.1, "Applications of module R&S OSP-B103", on page 235.
The input and output channels are independent of each other. The output pattern (Fig-
ure 3-24) depends on your settings, the input pattern (Figure 3-25) can be arbitrary.
●
The output channels are available on the first 16 sockets of the lower D-Sub connector (female). The remaining sockets 17 to 25 are connected to +28 V. All output
channels can be programmed independently from each other. You can use the output port for external relays that require up to 28 V switching voltage, as, for example, in Figure 6-2.
Each output channel is designed as a MOS-FET (open drain) that leaves the channel's pin on high impedance in the inactive state. When activated, the FET
switches the pin to internal ground. Each output is protected by two TVS diodes
against transient disturbances, which can occur when switching inductive loads
such as relay coils.
●
The input channels for +3.3 V TTL signals (tolerating up to +5 V, see below) are
available on the first 16 pins of the upper D-Sub connector (male). The remaining
pins 17 to 25 are connected to ground (GND). The module's dialog in the firmware
and the SCPI command READ:IO:IN? can read and show the state of the input
channels at any time. Each input channel is protected by a lowpass filter and two
TVS diodes against transient disturbances. If your application requires a voltage
together with the input channels, you can use the 28 V supplied by the output connector, or use an external voltage source.
Do not overload the input: for voltages > 5 V DC up to 28 V DC, insert a 22 kΩ resistor, see Chapter 2.1.11, "Connecting control cables", on page 21.
The switch unit provides power supply and control via a single module bus cable to a

The 5th port of the R&S OSP-B104 (in the module panel's top position) is a female 15pin D-Sub connector, labeled [IN / OUT]. The input and output channels are described
in Chapter 6.2.3, "Input ports of R&S OSP-B104", on page 242 and Chapter 6.2.4,
"Output ports of R&S OSP-B104", on page 242. This port is independent from the
[RELAY] ports. It supports basic simultaneous monitoring functions, including interlock
handling.
●
The module's dialog in the firmware (Figure 3-28) and the SCPI command READ:
IO:IN? can display and query the state of the input channels at any time.
●
You can use the output pins 2 to 6 and the input pins 10 to 13 as auxiliary lines.
Each output channel is designed as a MOS-FET (open drain) that leaves the channel's pin on high impedance in the inactive state. When activated, the FET
switches the pin to internal ground. You can use pin 1 (+28 V DC) or an external
voltage source (maximum 28 V DC). The maximum current load is 200 mA per output channel.
Do not overload the input: for voltages > 5 V DC up to 28 V DC, insert a 22 kΩ resistor, see Chapter 2.1.11, "Connecting control cables", on page 21.
Transfer switches
The external DPDT power-transfer relays require being switched by control pulses
(rather than by constant levels). The R&S OSP supports this control scheme by two
lines ("Set A" and "Set B") that set the switch to each position.
●
If an external relay is not activated ("Set B" pulse sent to the relay), the terminals
1 + 4 and 2 + 3 are connected and remain latched
●
If an external relay is activated ("Set A" pulse sent to the relay), the terminals 1 + 2
and 3 + 4 are connected and remain latched
Note that these activation or connection states are in contrast with other DPDT
switches, like R&S OSP-B114, R&S OSP-B116x and R&S OSP-B136.
The user interface (Figure 3-28) displays the state of the external relays.
All external relays connected to the R&S OSP-B104 (up to 4 relays) operate independ-
ently from each other.
Note that the functions Reset All Switches and General > Switch-On Reset in the user
interface and the RC command CONFigure:POWerup:RESet do not change the
state of the external relays. Also, the output channels of the module R&S OSP-B104
remain unchanged upon these reset commands.
The Spinner power-transfer relays support the “carrier safety contact” concept. While
turning from one switch position to the other, the carrier safety contact remains open. If
you include this contact into the interlock path, the power amplifier connected to the
interlock control is deactivated while the relay is turning. In the final relay position, the
carrier safety contact closes again, thus closing the full interlock chain. Only then, the
power amplifier can return to operational mode.

Delay time
The external power-transfer relays connected to the R&S OSP-B104 can have a significant settling time. Especially transfer relays with a motor drive can require tens of milliseconds to reach their final position.
To prevent sending a new command before a relay has reached its final position, the
switch unit allows defining a delay time between sending two consecutive commands.
Per default, a delay time of 100 ms is set for the R&S OSP-B104 module. If the controller brings up a switching error, possibly the delay time is set too short.
Refer to Figure 3-29 and to CONFigure:RELay:DELay on page 278 for further information on how to change the delay time.
The Spinner power-transfer relays have an output contact indicating their position. If
you connect this contact to the "Status" pin (pin 2) of the corresponding [RELAY] connector, the R&S OSP can read and display the current state of the external relay.
The module has 6 status LEDs:
●
For each [RELAY] connector, left and right of these connectors, there is a "[PWR]"
LED, labeled 1 to 4.
– If a [PWR] LED shows green light, the voltage on pin 1 of this connector is OK
(+24 V).
– If the LED is off, there is a problem with the power on the corresponding con-
nector. In such a case, turn off the R&S OSP, eliminate possible errors in the
cabling or the connected relay, turn the switch unit back on and check the LED
again.
●
Centered between the lower [RELAY] connectors, there are two more LEDs:
The upper "[PWR I/O]" LED gives the same voltage status information as described above for pin 1 (+28 V) of the I/O connector.
– If the LED shows green light, the power is OK.
– If the LED is off, there is a problem with the power on the corresponding con-
nector. In such a case, turn off the R&S OSP, eliminate possible errors in the
cabling or the connected device, turn the switch unit back on and check the
LED again.
●
The lower "[INTERLOCK]" LED shows the state of the interlock (pins 7 and 15).
– If the LED is off, it indicates that the interlock is closed. In this state, the remote
control command READ:MOD:INT? returns the value "1".
– If the LED shows red light, there is no connection between the pins 7 and 15.
This state either indicates an open interlock, or at least in one of the [RELAY]
connectors, pins 3 and 4 are not connected. If the interlock is open, the remote
control command READ:MOD:INT? returns the value "0".
Use a bridge between the interlock pins or "carrier safety contacts" of unused relay
connectors, see Figure 6-5. Bridging is especially relevant, if the interlock pins of all
connectors (also unused connectors) are used in a serial interlock loop. For example,
use a special bridging connector to bridge the pins, as described in Chapter 6.2.1,

If this module is not factory-mounted, contact Rohde & Schwarz service for mounting it.
The two-slot (double-width) module R&S OSP-B106 (order no. 1505.5601.02) consists
of 6 failsafe electromechanical non-terminated SPDT relays: 3 with BNC (female) connectors and 3 with N (female) connectors.
The SPDT relays K1 to K3 with N-type connectors are suited for a frequency range
from DC to 12.4 GHz.
The SPDT relays K4 to K6 with BNC connectors can be used at frequencies up to
900 MHz. At DC voltages up to a maximum of 30 V DC, these relays are suited for currents of up to 2 A.
Note: Mind the torque recommendation of 150 N·cm for N connectors.
The relays operate independently from each other. The terminal port is labeled with C
(common), the other relay ports are labeled with NC (normally closed) and NO (normally open). Terminal C is connected either with relay port NC or NO.
The type of relays is monostable (or "failsafe"), hence, with no voltage applied, an RF
connection is provided from C to NC, while NO is not connected to C ("Pos = 0"). To
disconnect NC and connect C to NO ("Pos = 1"), a continuous voltage must be applied
to the relay.
The relays are mounted directly into the module's panel and soldered to the module's
printed board, to avoid relay cabling and allow a compact module size.
The switch unit provides power supply and control via a single module bus cable to a
module bus connector on the module's printed board. The module's on-board memory
stores its configuration data.

After a reset, SSRs automatically go to the default state (control voltage = logical 0)
with an RF connection from C to NC, while NO is not connected to C. To disconnect
NC and connect C to NO, an SSR must be activated (control voltage = logical 1).

R&S
Figure 3-36: R&S OSP-B108
The one-slot module R&S OSP-B108 (order no. 1505.5718.02) is a four-times, one-tosix multiplexer (4x SP6T) for DC signals from 0 V to 30 V, with 60 VA maximum power
(same level for all pins). The maximum resistive load is 2 A at 30 VDC.
The multiplexer consists of four coupled SP6T relays. It has 1 male input connector
and 3 female output connectors. The module is controlled by a logic interface and
switches up to 4 input channels to one out of 6 output positions.
A typical application example with this module is multiplexing of power supply (two
power lines with force and sense wires, hence 4 wires all together) to up to 6 DUTs.
The relay type is electromechanical failsafe (open). Hence, without a control signal no
connections are made and the relay goes to its reset state, in which the common terminals are not connected to any output pins.
●
The 4 input channels are available on the first 8 pins (in groups of 2) of the upper
left 9-pin D-Sub connector (male). The remaining pin 9 is connected to ground
(GND), see Figure 3-37.
Note that these input pins are not read-out in any way by the switch unit. Instead,
the inputs are only switched in a direct connection to the selected output ports, as
described below. Also, signals can travel in a bidirectional way, hence, you can use
the output ports as inputs, and vice versa.
●
The output channels are available on the first 8 sockets, each, of the 3 other 9-pin
D-Sub connectors (female). The remaining socket 9 of each output port is connected to GND, see Figure 3-37.
The channels are grouped on the connectors:
– Channel 1+2 are on the lower right OUT connector
– Channel 3+4 are on the upper right OUT connector
– Channel 5+6 are on the lower left OUT connector
The switch unit provides power supply and control via a single module bus cable to a
module bus connector on the module's printed board. The module's on-board memory
stores its configuration data.

Terminal C is connected either with relay port "1" or "0". (In modules manufactured
before 2021, the default port was labeled "2" instead of "0".)
Note that the hardware labels "0" and "1" are represented in the software as positions
"0" (= default) and "1", respectively. In RC commands, the corresponding switching
states are encoded by the SCPI parameters "00" (= default) and "01".
The relay type is bistable (or "latching"), hence, with no voltage applied, a relay
remains in its current position.
To change the connection, the controller must send a voltage pulse to the appropriate
switch coil in the relay. After that, no energy is consumed by this relay type.
You can configure two different Power Up reset conditions to determine, how
latching relays behave after booting the switch unit.
The relays are mounted directly into the module's panel and soldered to the module's

The relays operate independently from each other. The terminal port is labeled with C
(common), the other relay ports are labeled with numbers "0" (= default port) and "1".
Terminal C is connected either with relay port "1" or "0". (In modules manufactured
before 2021, the default port was labeled "2" instead of "0".)
Note that the hardware labels "0" and "1" are represented in the software as positions
"0" (= default) and "1", respectively. In RC commands, the corresponding switching
states are encoded by the SCPI parameters "00" (= default) and "01".
The relay type is bistable (or "latching"), hence, with no voltage applied, a relay
remains in its current position.
To change the connection, the controller must send a voltage pulse to the appropriate
switch coil in the relay. After that, no energy is consumed by this relay type.
You can configure two different Power Up reset conditions to determine, how
latching relays behave after booting the switch unit.
The relays are mounted directly into the module's panel and soldered to the module's
printed board, to avoid relay cabling and allow a compact module size.
The switch unit provides power supply and control via a single module bus cable to a
module bus connector on the module's printed board. The module's on-board memory
stores its configuration data.

Modules
OSP-B114 EMS test control module
R&S
The module is designed for the following tasks in small or medium systems for electromagnetic susceptibility (EMS) measurements:
●
IN
The male D-Sub 9 connector labeled "IN" provides 4 input channels and 5 other
lines, as shown in Figure 3-65:
– The 4 digital input channels (input lines at pins 4, 5, 8 and 9) have no influence
on the module's internal interface logic. Instead, you can read out the state of
these universal IN channels to your external computer. You can use these IN
channels, for example, for controlling your application by the state of various
door contacts or light grids.
These 4 input channels are specified for up to 5 V (TTL). If you use a higher
voltage level up to +28 V DC (as provided by pin 6, for example), do not over-
load the input: for voltages > 5 V DC up to 28 V DC, insert a 22 kΩ resistor,
see Chapter 2.1.11, "Connecting control cables", on page 21.
The input channels can be read at any time. Each channel is protected by a
lowpass filter and two TVS diodes against transient disturbances.
– Pin 1 is a ground contact.
– Use the "Interlock Loop" line on pin 2 together with pin 6 ("+28 V DC") to con-
nect the interlock door contact. Hence, pin 2 provides the basic door-state
information to the module's interlock logic.
– The "PA Interlock Control 1" circuit between pin 3 and pin 7 is controlled by the
module's interlock logic. This circuit can, for example, shut down (power off) an
external RF power amplifier, if the interlock loop is open.
The module's dialog in the firmware (Figure 3-66) and the SCPI command READ:
IO:IN? can display and query the state of the input channels at any time.
●
OUT
The female D-Sub 9 connector labeled "OUT" provides 4 output channels and 5
other lines, as shown in Figure 3-65:
– The 4 digital output channels at pins 1, 2, 6 and 7 can be programmed inde-
pendently from each other. You can use the OUT channels, for example, for
controlling the position and polarization of the transmitting antennas.
These lines are specified, each, for a maximum load of 200 mA at 28 V DC.
The maximum total load on the module is 600 mA, as specified in the data
sheet. Each output channel is designed as a MOS-FET (open drain) that
leaves the channel's pin on high impedance in the inactive state. When activa-
ted, the FET switches the pin to internal ground. Each output is protected by
two TVS diodes against transient disturbances, which can occur when switch-
ing inductive loads, such as relay coils.
– Pin 5 is a ground contact.
– Pin 3 of the output port ("Interlock LED" in Figure 3-65) is controlled by the
module's interlock logic and activated together with the "INTLK LED". It is
specified at a maximum of 100 mA. Hence, you can use pin 3 and pin 9
("+28 V DC") of the output port to control a remote LED or a different indicator
in a separate location, as in Figure 3-65. For example, this indicator can be on
the front panel of a rack or in an office.
– The "PA Interlock Control 2" circuit between pins 4 and 8 is controlled by the
module's interlock logic, too. This circuit can, for example, shut down (power

off) another external RF power amplifier, if the input port's interlock loop is
open.
●
DPDT
The electromechanical DPDT power relay R1 can switch the RF output of two
power amplifiers to one or two transmitting antennas or other transducers. It has 4
numbered terminal ports and is suited for a frequency range from DC to 12.4 GHz.
For power ratings, refer to the data sheet.
The type of relays is monostable (or "failsafe"), showing the following behavior:
– When the relay is not activated (no voltage applied) and after a reset, the ter-
minals 1 + 2 and 3 + 4 are connected (this state is also the automatic default)
– When the relay is activated, the terminals 1 + 3 and 2 + 4 are connected
●
SPDT
The internally terminated solid-state relay (SSR) K14 of SPDT type is controlled by
the interlock and suited for a frequency range from 9 kHz to 10 GHz.
The terminal port is labeled with C (common), the other relay ports are labeled with
NC (normally closed) and NO (normally open). Terminal C is connected either with
relay port NC or NO.
The relay shows the following behavior:
– When the relay is activated (control voltage = logical 1, typically when the inter-
lock loop is closed), the relay connects C to NO, while disconnecting NC.
– When the relay is not activated (control voltage = logical 0, typically when the
interlock loop is open) and after reset, the relay automatically falls back to its
default state: It has an RF connection from C to NC, while NO is not connected
to C.
You can use this relay position to disconnect the signal generator from the power
amplifier. Hence, K14 can implement an additional safety feature, if the D-Sub output cannot shut down the amplifier. In this case, you can use the SPDT switch for
directly interrupting the RF signal, typically between the signal generator and the
power amplifier.
However, without power supplied to the relay, it has no defined switching state.
Therefore, SSRs are not inherently failsafe, see "Monostable vs. failsafe"
on page 11.
●
INTLK LED
The status LED that is labeled [INTLK] can display the current state of the interlock
loop:
– If the LED is off, it indicates that the interlock is closed.
– If the LED shows red light, there is no connection between the input port's pins
2 ("Interlock Loop") and 6 ("+28 V DC") of the input port (see Figure 3-65). It
indicates that the interlock is open.
The relays and I/O ports are mounted directly into the module's panel and soldered to
the module's printed board, to avoid relay cabling and allow compact module size.
The switch unit provides power supply and control via a single module bus cable to a
module bus connector on the module's printed board. The module's on-board memory
stores its configuration data.

From this dialog, you cannot control the SPDT relay (center position in Figure 3-64),
because it is controlled only by the module's internal interlock circuitry:
●
If the "Interlock" state is "Closed", the SPDT relay connects C to NO.
●
If the "Interlock" state is "Open", the SPDT relay connects C to NC.

state.
