Introduction
Notes
1-4Operating Manual: PSS67 F 16DI SB-T
Overview
The module PSS67 F 16DI SB-T can be used in a rugged industrial
environment up to protection type IP67.
It has 16 digital inputs and 4 dedicated test pulse outputs.
The inputs are suitable for connecting single or dual-channel safety-related
input devices, with or without test pulses. The inputs can be assigned to
two I/O-Groups on SafetyBUS p.
The 4 test pulse outputs are available via 8 M12 plug-in connectors. The
test pulses are permanently assigned to the inputs. The test pulse outputs
can also be configured as 24 VDC outputs.
The PSS67 F 16DI SB-T requires a 24 V supply, which provides power to
both the module electronics and the dedicated test pulse outputs.
The module is isolated from SafetyBUS p through optocouplers.
NOTICE
Before installing the module you should read and take note of the
information contained in the “SafetyBUS p Safety Manual”.
The PSS67 F 16DI SB-T is a decentralised input module designed for use
on SafetyBUS p, where it has the function of an “Input/Output Device”.
The following is deemed improper use:
• Any component, technical or electrical modification to the digital input
module
• Use of the digital input module outside the areas described in this
manual
• Use of the digital input module outside the documented technical details
(see chapter entitled “Technical Details”).
3-1Operating Manual: PSS67 F 16 DI SB-T
Safety
Categories in accordance with EN 954-1
WARNING!
Please note: To achieve the corresponding category or requirement class,
the whole system including all safety-related components (parts, devices,
user program etc.) must be included in the assessment. For this reason,
Pilz cannot accept liability for the correct classification into a category or
requirement class.
Digital inputs
Depending on the application area and its respective regulations, the
inputs may be used without test pulses for applications up to Category 3,
in accordance with EN 954-1. The possibility of a short circuit occurring in
the external wiring between different inputs or against the supply must be
eliminated through appropriate wiring.
For Category 4 applications, shorts between the input contacts must be
detected. This can be achieved through the use of the module’s test pulses
or, depending on the type of input device, through a feasibility test or
through detection of shorts across the contacts on the input device (e.g.
light grid) (for connection examples please see “Wiring the Inputs and
Outputs”).

3-4Operating Manual: PSS67 F 16DI SB-T
Function Description
Inputs
Single and dual-channel input devices can be connected to the inputs, with
or without test pulses. The inputs are equipped with input filters.
Input signals must show a “High” (“1” signal) of 15 VDC (+15 ... +30 VDC)
and a “Low” (“0” signal) of 0 VDC (-3 ... +5 VDC).
The input status is signalled to the CPU on the controlling PSS via
SafetyBUS p. Green LEDs indicate the status of the inputs. An LED lights
up as soon as a “1” signal is present at the input.
Diagnostic circuitry checks the function of the inputs and the input filter. If
an error is detected, all the outputs in the affected I/O-Group are shut down
and the I/O-Group switches to a STOP condition. The module then triggers
an error telegram on SafetyBUS p and stores the error in its error buffer.
Where test pulses are not used, inputs with single-channel input devices
can be used in applications up to and including Category 2 in accordance
with EN 954-1; in the case of dual-channel input devices, this extends to
Category 3 applications. The possibility of a short circuit occurring in the
external wiring between different inputs or against the supply must be
eliminated through appropriate wiring.
Test pulses must be used for applications with single-channel input
devices above Category 2 and for applications with dual-channel input
devices above Category 3.
Connection examples can be found in the chapter entitled: “Wiring the
Inputs and Test Pulse Outputs”.
The inputs can be assigned to two I/O-Groups. Please refer to the section
entitled “Setting the device address”.
Operating Manual: PSS67 F 16DI SB-T
4-1
Function Description
Signal detection at the inputs
To guarantee that a signal at an input (“0” signal or “1” signal) is detected, it
must be present for a certain time period. This period must be longer than
the event timeout configured in the PSS WIN-PRO system software. Once
a signal has been detected, a corresponding event telegram will be
triggered.
A signal (“0” signal or “1” signal) is ignored if it does not exceed the pulse
suppression time of 300 µs. In this case, no event telegram is triggered.

Fig. 4-1: Signal detection at the inputs
Signal change behaviour
If a signal at an input changes, the module will send an event telegram.
The module must then wait for a confirmation telegram (ACK) from the
Master LD before it can send out a new event telegram.
If there is another signal change while the module is waiting for the
telegram, the module’s behaviour will depend on the configured signal
change behaviour.

4-2Operating Manual: PSS67 F 16DI SB-T
Two behaviour modes can be configured in the software’s configurator:
• “default”:
The signal changes are not registered.
• “Fast”:
Each signal change is temporarily stored in a FIFO telegram buffer. Once
the confirmation telegram arrives, the module sends consecutive event
telegrams for each detected signal change from the FIFO telegram buffer.
Test pulse outputs/24 VDC pins
The four test pulse outputs T0 to T3 may only be used for test pulses or as
24 VDC outputs.
The test pulse outputs are suitable for testing the wiring of input devices.
All safety-related inputs must operate in accordance with the failsafe
principle (on switching off).
Two test pulses are available on each plug-in connector; these test pulses
are permanently assigned to the inputs. The assignment of the test pulses
to the inputs cannot be changed in the system software’s configurator.
If the test pulse outputs are not being used, they can be configured as
24 VDC pins in the system software’s configurator (default setting).

Installation
Caution!
Electrostatic discharge can damage components on the
PSS67 F 16DI SB-T.
Ensure against discharge before touching the module, e.g. by touching an
earthed, conductive surface or by wearing an earthed armband.
The unit must be fastened to a flat mounting surface, so that there is no
strain on the housing when the module is screwed down. The mounting
distances will depend on which plug-in connectors are used and the
bending radius of the cables
To install the system, proceed as follows:
• Drill 2 x M4 holes (internal thread) in the mounting surface, as shown in
• Connect the functional earth to the upper fixing screw. If the functional
Fig. 5-1 (tolerance: ± 0.2 mm/0.01").
earth cannot be connected to the upper fixing screw, you will need to
connect the functional earth to Pin 5 of the M12 connector for the supply
voltage.
• Use two fixing screws to attach the module to the mounting plate.

Supply Voltage
Please note the following:
• When selecting the power supply, please refer to the requirements stated
under “Technical Details”.
• Overvoltage or interference voltage can damage or even destroy the
electronics on the PSS67 F 16DI SB-T. If this occurs, the affected I/OGroups will switch to a STOP condition and all the outputs in the affected
groups will be switched off. You should therefore take note of the relevant
EMC measures.
• WARNING!
Safe electrical isolation must be ensured for the external 24 V supply.
Failure to do so could result in electric shock. Power supplies must
conform to EN 60950, section 2.3, EN 60742 or EN 50178.
• To achieve the lowest possible residual ripple, we recommend that you
install a three-phase bridge rectifier or regulated supply.
• The “Ground” connection to the earth bar or earth fault monitor must be in
accordance with the relevant national regulations (e.g. EN 60204-1,
NFPA 79:17-7, NEC: Article 250).
INFORMATION
The module’s output circuits have been designed to guarantee maximum
safety. To achieve this, extensive tests are carried out internally.
Momentary interruptions to the “Supply” voltage during a test procedure
can falsify the test result, causing the following malfunction:
If the “Supply” voltage is interrupted momentarily, the unbuffered test pulse
outputs will transmit a “0” signal. The buffered module electronics reads
this signal at the pulsed inputs, thereby triggering the user's programmed
reaction. Example: The system reacts as though an E-STOP button has
been operated, although this is not the case: there has been a supply
interruption.
Remedy: “Supply” must be buffered.

This chapter describes the safety-related wiring of the digital inputs plus
the test pulse outputs.
CAUTION!
In order to guarantee protection type IP67, unused connectors should be
sealed using the blind plugs supplied.
CAUTION!
Make sure that the plug-in connectors are connected to the input devices
correctly. Once you have run a function test to check that the connectors
are connected to the input devices correctly, the inputs should be labelled.
If the inputs are connected to the input devices incorrectly, life-threatening
situations may arise on the plant.
INFORMATION
We recommend you use ready-made connectors to connect the inputs and
test pulse outputs.
INFORMATION
Please refer to the technical details for information on the maximum cable
runs when connecting input devices.
Operating Manual: PSS67 F 16DI SB-T7-1
Wiring
Notes on wiring
Where safety-related applications are concerned, it is essential that short
circuits and open circuits are unable to cause a hazardous condition within
a plant.
WARNING!
Safe separation is required when connecting a device with a circuit with
over 25 V AC or 60 V DC
The following terms are important:
• Signal inputs with frequent operation
These are signals that change status on several occasions within a
period of time.
• Single-channel safe input devices
These are positively-driven, normally-closed contacts which open on
actuation (failsafe principle).
• Elimination of short circuits between signals
This is possible within electrically-enclosed areas and also outside
electrically-enclosed areas for signals conducted in different multicore
cables. However, all components must meet the relevant regulations in
accordance with EN, DIN and VDE.
• In principle, the possibility of earth faults and open circuits cannot be
eliminated. With multi-channel input devices with frequent operation,
short circuits and open circuits can be detected via feasibility checks in
the control program.
The input test on the module uses test pulses to enable the operating
program of the PSS67 F 16DI SB-T to carry out a test to detect open
circuits and short circuits. The following pages contain details of
connection examples which may be of use when wiring the unit.
Labelling the module
You can label the SafetyBUS p and supply voltage connections, as well as
the inputs. 12 blank labels are supplied with the module. In addition you
can order a DIN A4 sheet with 264 labels as an accessory (order
no. 331 250).

Example: Dual-channel, failsafe input device, with test pulse
Features:
• Depending on the application area and its respective regulations, this
connection diagram is suitable for applications up to Category 4 in
accordance with EN 954-1.
• This type of connection is mainly used for signal inputs with infrequent
operation.
• On input devices with identical channels, each channel should be given
a separate test pulse, where possible. This will ensure that all short
circuits are detected, with the exception of short circuits which short out
the input device (cable from the test pulse to the input device and cable
from the input device to the input).
• If the input device has only one test pulse, a short circuit between the
cables from the input device to the inputs will not be detected. In this
case the unit should be suitably wired to avoid the risk of this type of short
circuit. If diverse input devices are used, this type of error will be

SafetyBUS p Interface
The module is connected to SafetyBUS p using a 5-pin A-coded M12
connector (X9). A 5-pin A-coded M12 socket (X10) is available to distribute
the bus signal to the other bus subscribers.
The X10 socket can also be used for bus subscriber termination.
To avoid reflection on the bus cable, the last bus subscriber must be fitted
with a terminating resistor. If the module is connected using 1:1 connection
cable, the terminating resistor is plugged into the free X10 socket . The
M12 terminator (Order no. 311 032) PSS SB M12 TERMINATOR is used
for termination via the SafetyBUS p socket.

Operation and Maintenance
Setting the device address
In order to operate the module on SafetyBUS p you will need to set the
device address that was defined for the module in the system software’s
configurator.
To do this you will need to use a screwdriver to open the transparent cover
on the rotary switches.
Use the rotary switches to set the required address. The rotary switch
labelled “x1” is used to set the units and the rotary switch labelled “x10” is
used to set the tens.
Permitted device addresses are in the range 32D ... 95D. The same applies
if the module is configured for SafetyBUS p 1 in the
SafetyBUS p Configurator on the PSS WIN-PRO system software. The
offset of 100D for device addresses on SafetyBUS p 1 is calculated
automatically from the bus configuration.

The I/O-Groups to which the module belongs must also be defined in the
system software’s configurator.
The module can be divided into sections A and B for this purpose. Section
A and section B may belong to different I/O-Groups. The module may either
have section A alone, section B alone, or both section A and section B. The
inputs can be assigned to both sections at will.
Membership of section A or section B is used in conjunction with the
device address to form the addresses under which the inputs can be
addressed by the controlling PSS.

Example:
Device address 51D
In the process image of the controlling PSS, the inputs from Section A are
addressed under the device address as slot number and bit number
9-2Operating Manual: PSS67 F 16DI SB-T
0 ... 15. The inputs from Section B are addressed under the device address
as slot number and bit number 16 ... 31; this corresponds to an offset of 16
in the bit number.
So if input I6 from Section A is reconfigured into Section B, for example, the
address will change from x.06 to x.22.
Any errors made when setting the device address will result in the loss of
the safety function.
If the same device address is set on two modules or the device addresses
of two modules are transposed, the controlling PSS may unknowingly
address the wrong inputs/outputs.
This will cause the plant to malfunction. The safe operation of the plant is
no longer guaranteed.
To avoid this, the greatest possible care must be taken when setting the
device addresses.
The device address may not be modified while the module is being
operated on SafetyBUS p (“SB active” LED lights up green or flashes),
otherwise all the I/O-Groups configured on the module will switch to a
STOP condition.
If it is necessary to change the set device address while the bus is running,
you will need to disconnect the module from SafetyBUS p while you make
the change. When you re-establish the connection to SafetyBUS p, the
module will quickly be ready for operation again (“Device” LED lights up
green).

Operation and Maintenance
Display elements
Status LEDs
Each input is assigned a status LED (I00 to I15).
The corresponding LED will light when its respective input has the status
“1”, otherwise it will remain unlit.
“Supply” LED
Indicates the presence of the supply voltage, “Supply”.
“Device” LED
This dual-colour LED indicates the device status.
• Red: A device error has occurred. The device error may involve one or
both of the I/O-Groups configured on the module.
• Flashing red: There is a periphery error.
• Green: The module is operating without error.
• LED off: A system error is preventing the module from starting up.
“SB active” LED
Indicates the presence of a connection between the module and the
Management Device.
• Green: Connection to the Management Device has been established
• LED off: No contact with SafetyBUS p (faulty wiring or Management
Device not in operation)
• Flashing green: There is contact with SafetyBUS p, but the Management
Device does not recognise the module (faulty device address or
configuration)
“I/O-Group” LED
Indicates the status of the I/O-Groups configured on the module.
• Green: All I/O-Groups configured on the module have “RUN” status
• LED off: All I/O-Groups configured on the module have “STOP” status
• Flashing green: One of the I/O-Groups configured on the module has
“STOP” status.

Recommissioning
NOTICE
When recommissioning, errors may occur when plugging in the connectors
as there is no protection against them being inserted incorrectly. Always
carry out a function test when recommissioning to ensure you exclude the
possibility of such an error.
Faults
If the module is defective or there is a wiring error, all the outputs in the
affected I/O-Group are shut down and the I/O-Group switches to a STOP
condition. An error telegram is then triggered on SafetyBUS p and the error
is entered in the error buffer of the PSS67 F 16DI SB-T.
An error message appears on the display of the controlling PSS. The error
stack display in the programming device can be used to locate the error
(see “SafetyBUS p System Description”).
Module configuration
The procedure for configuring SafetyBUS p and the module PSS67 F 16DI
SB-T is described in the online help of the PSS WIN-PRO system software.
