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 screwdriver.
6. To allow communication between the controller and module, move the bus
lever fully to the left (4) until it clicks, making sure 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 be sure of proper electrical connection. Securely
locking together the bus connectors is required for use in hazardous locations.
For more information on hazardous locations, see page 4.
7. Attach an end-cap terminator (5) to the last module in the system by using
the tongue-and-groove slots as before.
8. Lock the end-cap bus terminator (6).
IMPORTANT
You must use a 1769-ECR (right) or 1769-ECL (left) end cap to terminate the end
of the serial communication bus. An I/O configuration fault will occur if an end
cap is not used.
Replace 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 Remove Power on page 3.
2. Remove the upper and lower mounting screws from the module or open the
DIN latches by using a flat-blade or Phillips screwdriver.
3. Move the bus lever to the right to disconnect or 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.

Compact I/O Analog Output Module
5. Gently slide the disconnected module forward.
If you feel excessive resistance, check that the module is disconnected from
the bus and that both mounting screws are 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. Be sure that the bus lever on the module and on the right-side adjacent
module are in the unlocked (fully right) position before installing the
replacement module.
7. Slide the replacement module into the open slot.
8. Connect the modules 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.

Mount Module to Panel
Mount the module to a panel by using two screws per module. Use M4 or #8
panhead screws. Mounting screws are required on every module.
Mount Module to Panel by Using the Dimensional Template
Host Controller
122.6 mm
(4.826 in.)
132 mm (5.197 in.)
Spacing for single-wide modules 35 mm (1.378 in.)
Spacing for one-and-a-half wide modules 52.5 mm (2.067 in.)
Refer to host controller documentation for this dimension.
NOTE: Overall spacing
tolerance ±0.44 mm (0.016 in.)
Locate holes every 17.5 mm (0.689 in.) to allow for a mix of single-wide and
one-and-a-half-wide modules (for example, the 1769-OA16 module).
Mount Module to Panel by Using Modules as a Template
This procedure lets you use the assembled modules as a template for drilling holes
in the panel. See Mount Module to Panel by Using the Dimensional Template on
page 9 if you have sophisticated panel mounting equipment.
On a clean work surface, assemble no more than three modules.
Due to module-mounting hole tolerance, it is important to follow this procedure.
1. Using the assembled modules as a template, carefully mark the center of all
module-mounting holes on the panel.
2. Return the assembled modules to the clean work surface, including any
previously mounted modules.
3. Drill and tap the mounting holes for the recommended M4 or #8 screws.
4. Place the modules back on the panel, and check for proper hole alignment.
Publication 1769-IN087A-EN-P - August 2009

Compact I/O Analog Output Module
5. 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 the remounting time during drilling and tapping of
the next group.
6. Repeat steps 1 to 6 for any remaining modules.
Mount Module to a DIN Rail
The module can be mounted by using these DIN rails:
• 35 x 7.5 mm (EN 50 022 - 35 x 7.5)
• 35 x 15 mm (EN 50 022 - 35 x 15)
To mount the module on a DIN rail, follow these steps.
1. Close the DIN rail latches.
2. Press the DIN-rail mounting area of the module against the DIN rail.
The latches will momentarily open and lock into place.

Ground 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,
Allen-Bradley publication 1770-4.1, for additional information.
System Wiring Guidelines
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)
• 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.(2)
• Voltage outputs (Vout 0+…Vout 3+) of the 1769-OF4 module are referenced
to ANLG COM. Load resistance for a voltage output channel must be equal
to or greater than 1K Ω .
• Current outputs (Iout 0+…Iout 3+) of the 1769-OF4 module source current
that returns to ANLG COM. Load resistance for a current output channel
must remain between 0 and 600 Ω .
ATTENTION
Be careful when stripping wires. Wire fragments that fall into a module
can cause damage at power up. Once wiring is complete, make sure the
module is free of all metal fragments.
(1)
In environments where high-frequency noise may be present, it may be necessary to directly ground cable shields to earth
at the module end and via a 0.01µF, 2000V capacitor at the sensor end.
(2)
Cable length over 50 meters may impact accuracy. For details, refer to the Compact I/O Analog Output Module User
Manual, publication 1769-UM020.

ATTENTION
Analog outputs may fluctuate for less than a second when power is applied
or removed. This characteristic is common to most analog outputs. While
the majority of loads will not recognize this short signal, take preventive
measures to make sure that connected equipment is not affected. Failure
to take these preventative measures may result in unexpected load
reactions.
Label 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.
Remove 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 location and type.

Wire 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. 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.
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 lb•in).
TIP
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.

Configuration Data File
The manipulation of 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 provided by the
programming software simplify configuration.
Some systems, like the 1769-ADN DeviceNet adapter system, 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, shown on the following page.

The over- or under-range flag will come on when either the High Clamp or the Low Clamp values are exceeded. When either
range flag is set, the module clamps the corresponding channel’s output to the High Clamp or the Low Clamp value. Unless
latched, the flag automatically resets when directed to a value between the High Clamp and the Low Clamp values. The
output channel value always returns to normal operation when directed to a value allowed by the High Clamp and Low
Clamp values (even if latching of the Clamp status bits is enabled).
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.
Includes offset, gain, drift, non-linearity, and repeatability error terms.
