Compact™ Solid State 24V dc Source Output Module 3
Module Installation
Compact I/O is suitable for use in an industrial environment when installed in
accordance with these instructions. Specifically, this equipment is intended for use
in clean, dry environments (Pollution degree 2
Over Voltage Category II
(2)
(IEC 60664-1).
Prevent Electrostatic Discharge
(1)
) and to circuits not exceeding
(3)
ATTENTION
!
Remove Power
ATTENTION
!
Electrostatic discharge can damage integrated circuits or
semiconductors if you touch bus connector pins. Follow these
guidelines when you handle the module:
• Touch a grounded object to discharge static potential.
• Wear an approved wrist-strap grounding device.
• Do not touch the bus connector or connector pins.
• Do not touch circuit components inside the module.
• If available, use a static-safe work station.
• When not in use, keep the module in its static-shield box.
Remove power before removing or inserting this module. When
you remove or insert a module with power applied, an
electrical arc may occur. An electrical arc can cause personal
injury or property damage by:
• sending an erroneous signal to your system’s field devices,
causing unintended machine motion
• causing an explosion in a hazardous environment
Electrical arcing causes excessive wear to contacts on both the
module and its mating connector. Worn contacts may create
electrical resistance.
(1) Pollution Degree 2 is an environment where, normally, only non-conductive pollution occurs except that occasionally a
temporary conductivity caused by condensation shall be expected.
(2) Over Voltage Category II is the load level section of the electrical distribution system. At this level transient voltages are
controlled and do not exceed the impulse voltage capability of the product’s insulation.
(3) Pollution Degree 2 and Over Voltage Category II are International Electrotechnical Commission (IEC) designations.

1. Disconnect power.
2. Check that the bus lever of the module to be installed is in the unlocked
(fully right) position.
3. Use the upper and lower tongue-and-groove slots (1) to secure the modules
together (or to a controller).
4. Move the module back along the tongue-and-groove slots until the bus
connectors (2) line up with each other.
5. Push the bus lever back slightly to clear the positioning tab (3). Use your
fingers or a small screw driver.
6. To allow communication between the controller and module, move the bus
lever fully to the left (4) until it clicks. Ensure it is locked firmly in place.
ATTENTION
When attaching I/O modules, it is very important that the
bus connectors are securely locked together to ensure
proper electrical connection.

the tongue-and-groove slots as before.
8. Lock the end cap bus terminator (6).
IMPORTANT
A 1769-ECR or 1769-ECL right or left end cap must be used to
terminate the end of the serial communication bus.
Mounting Expansion I/O
ATTENTION
During panel or DIN rail mounting of all devices, be sure that
all debris (metal chips, wire strands, etc.) is kept from falling
into the module. Debris that falls into the module could cause
damage on power up.

Panel Mounting Procedure Using Modules as a Template
The following procedure allows you to use the assembled modules as a template
for drilling holes in the panel. If you have sophisticated panel mounting equipment,
you can use the dimensional template provided on page 6. Due to module
mounting hole tolerance, it is important to follow these procedures:
1. On a clean work surface, assemble no more than three modules.
2. Using the assembled modules as a template, carefully mark the center of all
module-mounting holes on the panel.
3. Return the assembled modules to the clean work surface, including any
previously mounted modules.
4. Drill and tap the mounting holes for the recommended M4 or #8 screw.
5. Place the modules back on the panel, and check for proper hole alignment.
6. Attach the modules to the panel using the mounting screws.
TIP
If mounting more modules, mount only the last one of
this group and put the others aside. This reduces
remounting time during drilling and tapping of the next
group.
7. Repeat steps 1 to 6 for any remaining modules.
Publication 1769-IN054A-EN-P - April 2001
Compact™ Solid State 24V dc Source Output Module 7
DIN Rail Mounting
The module can be mounted using the following DIN rails: 35 x 7.5 mm (EN 50 022
- 35 x 7.5) or 35 x 15 mm (EN 50 022 - 35 x 15).
Before mounting the module on a DIN rail, close the DIN rail latches. Press the DIN
rail mounting area of the module against the DIN rail. The latches will momentarily
open and lock into place.
Replacing a Single Module within a System
The module can be replaced while the system is mounted to a panel (or DIN rail).
1. Remove power. See important note on page 3.
2. On the module to be removed, remove the upper and lower mounting
screws from the module (or open the DIN latches using a flat-blade or
phillips style screw driver).
3. Move the bus lever to the right to disconnect (unlock) the bus.
4. On the right-side adjacent module, move its bus lever to the right (unlock)
to disconnect it from the module to be removed.
5. Gently slide the disconnected module forward. If you feel excessive
resistance, check that the module has been disconnected from the bus, and
that both mounting screws have been removed (or DIN latches opened).
TIP
6. Before installing the replacement module, be sure that the bus lever on the
module to be installed, and on the right-side adjacent module are in the
unlocked (fully right) position.
7. Slide the replacement module into the open slot.
8. Connect the modules together by locking (fully left) the bus levers on the
replacement module and the right-side adjacent module.
9. Replace the mounting screws (or snap the module onto the DIN rail).
It may be necessary to rock the module slightly from
front to back to remove it, or, in a panel-mounted
system, to loosen the screws of adjacent modules.

Removing the Finger-Safe Terminal Block
When wiring field devices to the module, it is not necessary to remove the terminal
block. If you remove the terminal block, use the write-on label on the side of the
terminal block to identify the module slot lcation and type.
To remove the terminal block, loosen the upper and lower retaining screws. The
terminal block will back away from the module as you remove the screws. When
replacing the terminal block, torque the retaining screws to 0.46 Nm (4.1 in-lbs).

2. Route the wire under the terminal pressure plate. You can use the bare wire
or a spade lug. The terminals will accept a 6.35 mm (0.25 in.) spade lug.
TIP
3. Tighten the terminal screw making sure the pressure plate secures the wire.
Recommended torque when tightening terminal screws is 0.68 Nm (6 in-lbs).
TIP
The terminal screws are non-captive. Therefore, it is
possible to use a ring lug [maximum 1/4 inch o.d. with
a 0.139 inch minimum i.d. (M3.5)} with the module.
If you need to remove the finger-safe cover, insert a
screw driver into one of the square, wiring holes and
gently pry the cover off. If you wire the terminal block
with the finger-safe cover removed, you will not be
able to put it back on the terminal block because the
wires will be in the way.

The manipulation of the bits from this file is normally done with programming
software (e.g. RSLogix 500, RSNetworx for DeviceNet, etc.) during initial
configuration of the system. In that case, graphical screens are provided via the
programmer to simplify configuration. However, some systems (e.g. 1769-ADN
DeviceNet Adapter) also allow the bits to be altered as part of the control program
using communication rungs. In that case, it is necessary to understand the bit
arrangment.

Transistor Output Transient Pulses
The maximum duration of the transient pulse occurs when minimum load is
connected to the output. However, for most applications, the energy of the
transient pulse is not sufficient to energize the load.
ATTENTION
!
The graph below illustrates that the duration of the transient is proportional to the
load current. Therefore, as the on-state load current increases, the transient pulse
decreases. Power-up transients do not exceed the time duration shown below, for
the amount of loading indicated, at 60°C (140°F).
A transient pulse occurs in transistor outputs when the external
DC supply voltage is applied to the output common terminals
(e.g. via the master control relay). The sudden application of
voltage creates this transient pulse. This condition is inherent in
transistor outputs and is common to solid state devices. A
transient pulse can occur regardless of the controller having
power or not. Refer to your controller’s user manual to reduce
inadvertent operation.
