Compact 1769-OF8C Analog 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
(1)
) and to circuits not exceeding
Over Voltage Category II
(2)
(IEC 60664-1).
(3)
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.
• If available, use a static-safe work station.
• 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.
(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.

Compact 1769-OF8C Analog Output Module 5
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.
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
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.
Minimum Spacing
Maintain spacing from enclosure walls, wireways, adjacent equipment, etc. Allow 50 mm (2 in.) of space on all sides for adequate ventilation, as shown:

122.6±0.2
(4.826±0.008)
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-IN065B-EN-P - September 2005
Compact 1769-OF8C Analog 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).
Follow the steps below in order:
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 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.
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).

Field Wiring Connections
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,
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)
• 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.
• 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 and 500 Ω.
(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.

Compact 1769-OF8C Analog Output Module 9
External Power Switch
The 1769-OF8C has an external 24V dc power switch which gives you the option of using an external power supply. The switch is located in on the lower left portion of the module’s circuit board, as shown below. With this switch pressed on the top
(default), 24V dc power is drawn from the 1769 system power supply via the 1769
I/O bus. Pressed on the bottom, 24V dc power is drawn from the external power supply.
Wire the external power supply to the module via the module’s terminal block. The external power supply must be rated Class 2, with a 24V dc range of 20.4 to 26.4V dc and 160 mA minimum.

upper retaining screw wiring the finger-safe terminal block lower retaining screw
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. 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 Nm (6 in-lbs).
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 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 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 16. Refer to the Compact™ Analog I/O User
