Panel Mounting 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 9. Due to module
mounting hole tolerance, it is important to follow this procedure.
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.

10 CompactLogix Analog Output Module
5. Place the modules back on the panel, and check for proper hole
alignment.
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
ATTENTION: During panel or DIN rail mounting of all devices, be sure that
all debris (such as metal chips and wire strands is kept from falling into the
module. Debris that falls into the module could cause damage on power
up.
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). Follow the steps below:
1. Remove power.
See important note on page 6.
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 screwdriver).
3. Move the bus lever to the right to disconnect (unlock) the bus.
Rockwell Automation Publication 1769-IN089A-EN-P - March 2011
CompactLogix Analog Output Module 11
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
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.

System Wiring Guidelines
WARNING: EXPLOSION HAZARD
All wiring must comply with N.E.C. article 501-4(b).
Consider the following when wiring your system:
• All module commons (ANLG COM) are connected in the analog
module. The analog common (ANLG COM) is not connected to earth
ground inside the module.
• Channels are not 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.(1)
• To ensure 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.
IMPORTANT
To comply with UL restrictions, this equipment must be powered from a
source compliant with Class 2 or Limited Voltage/Current.
• Current outputs (Iout 0+ to Iout 7+) of the 1769-OF8C module source
current that returns to ANLG COM. Load resistance for a current
output channel must remain between 0…500 Ω.
• Voltage outputs (Vout 0+ to Vout 7+) of the 1769-OF8V module are
referenced to ANLG COM. Load resistance for a voltage output
channel must be equal to or greater than 1K W.
(1)
In environments where high frequency noise may be present, it may be necessary to ground the shield
via a 0.1µF capacitor at the load end and also ground the module end without a capacitor.
Rockwell Automation Publication 1769-IN089A-EN-P - March 2011
CompactLogix Analog Output Module 13

IMPORTANT
The output module’s input data file reflects the analog output data echo
of the module, not necessarily the electrical state of the output terminals.
It does not reflect shorted or open outputs.
Configuration Data File
The manipulation of the bits from this file is normally done with programming
software, such as RSLogix 500, 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 devices, 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 21. Refer to the
CompactLogix I/O Analog Modules User Manual, publication 1769-UM002,

(1)
The over- or under-range flag will come on when the normal operating range (over/under) is exceeded.
The module will continue to convert the analog input up to the maximum full scale range. The flag
automatically resets when within the normal operating range unless configured to latch.
(2)
If the optional 24V DC Class 2 power supply is used, the 24V DC current draw from the bus is 0 mA.
(3)
Step response is the period of time between when the D/A converter was instructed to go from
minimum to full range until the device is at 63% of full range.
(4)
Includes offset, gain, drift, non-linearity and repeatability error terms.
(5)
Output ripple is the amount a fixed output varies with time, assuming a constant load and
temperature.
(6)
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.
(7)
Rated working voltage is the maximum continuous voltage that can be applied at the input terminal,
including the input signal and the value that floats above ground potential (for example, 10V DC input
signal and 20V DC potential above ground).
(8)
Failure to use a Class 2 power supply without regulation within these limits could result in improper
module operation.
