Module Installation
Compact I/O is suitable for use in an industrial environment when installed
in accordance with these instructions.
Prevent Electrostatic Discharge
ATTENTION: Electrostatic discharge can damage integrated
circuits or semiconductors if you touch bus connector pins or the
terminal block. 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.
Use a static-safe work station, if available.
When not in use, keep the module in its static-shield box.
Remove Power
ATTENTION: 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.

Panel Mounting Procedure Using Modules as a Template
The following procedure lets you 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 10. 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.
Rockwell Automation Publication 1769-IN075B-EN-P - August 2010
Compact 1769-OF4CI Isolated Analog Output Module 11
6. Attach the modules to the panel by 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… 6 for any remaining modules.
DIN Rail Mounting
The module can be mounted using the following DIN rails:
• 35 x 7.5 mm (1.38 x 0.30 in.; EN 50 022 - 35 x 7.5)
• 35 x 15 mm (1.38 x 0.59 in.; 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). Follow the steps below in order:
1. Remove power.
2. On the module to be removed, remove the upper and lower mounting
screws from the module (or open the DIN latches by using a
screwdriver).
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.
Rockwell Automation Publication 1769-IN075B-EN-P - August 2010
12 Compact 1769-OF4CI Isolated Analog Output Module
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
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.
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).

Grounding the Module
This product is intended to be mounted to a well-grounded mounting surface,
such as a metal panel. Additional grounding connections from the module’s
mounting tabs or DIN rail (if used), are not required unless the mounting
surface cannot be grounded. Refer to Industrial Automation Wiring and
Grounding Guidelines, publication 1770-4.1, for additional information.
Rockwell Automation Publication 1769-IN075B-EN-P - August 2010
Compact 1769-OF4CI Isolated Analog Output Module 13
System Wiring Guidelines
Consider the following when wiring your system:
• Channels are isolated from each other.
• Use Belden 8761, or equivalent, shielded wire.
• Under normal conditions, the drain wire and shield junction must be
connected to earth ground, via a panel or DIN rail mounting screw at
the analog I/O module end. Keep the shield connection to ground as
short as possible.
TIP
In environments where high frequency noise may be present, it
may be necessary to ground the shield via a 0.1 µF capacitor at
the load end and also ground the module end without a capacitor.
• For optimum accuracy, limit overall cable impedance by keeping your
cable as short as possible. Locate the I/O system as close to your sensors
or actuators as your application will permit.
• Load resistance for each current output channel must remain between
0…500 Ω..
Wiring Output Devices
ATTENTION: Miswiring of the module to an AC/DC source will
damage the module.
Be careful when stripping wires. Wire fragments that fall into a
module could cause damage at power up. Once wiring is complete,
ensure the module is free of all metal fragments.
Rockwell Automation Publication 1769-IN075B-EN-P - August 2010

Labeling the Terminals
A removable, write-on label is provided with the module. Remove the label
from the door, mark the identification of each terminal with permanent ink,
and slide the label back into the door. Your markings (ID tag) will be visible
when the module door is closed.

Removing the Finger-safe Terminal Block
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 N•m
(4.1 in•lb).

Wiring the Finger-safe Terminal Block
When wiring the terminal block, keep the finger-safe cover in place.
1. Loosen the terminal screws to be wired.
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
The terminal screws are non-captive. You can use a ring lug
[maximum 6.35 mm (0.25 in.) o.d. with a 3.53 mm (0.139 in.)
minimum i.d. (M3.5)] with the module.
3. Tighten the terminal screw making sure the pressure plate secures the
wire. Recommended torque when tightening terminal screws is
0.68 N•m (6 in•lb).
TIP
If you need to remove the finger-safe cover, insert a screwdriver
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.

Configuration Data File
The manipulation of the bits from this file is normally done with programming
software (for example, RSLogix 500 software or RSNetworx for DeviceNet
software) during initial configuration of the system. In that case, graphical
screens are provided by the programmer to simplify configuration.
However, some systems, like the 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 arrangement. The channel
configuration words, the first two words of each eight word group, are described
on page 20. Refer to your module’s user manual for additional details.

(1)
Output ripple is the amount a fixed output varies with time, assuming a constant load and
temperature.
(2)
Repeatability is the ability of the output module to reproduce output readings when the same
controller value is applied to it consecutively, under the same conditions and in the same direction.
(3)
Rated working voltage is the maximum continuous voltage that can be applied at the output terminal,
including the output signal and the value that floats above ground potential (for example, 10V dc
output signal and 20V dc potential above ground).
