ATTENTION: This equipment is sensitive to electrostatic discharge, which

can cause internal damage and affect normal operation. Follow these guidelines when you handle this equipment:

• Touch a grounded object to discharge potential static.

• Wear an approved grounding wriststrap.

• Do not touch connectors or pins on component boards.

• Do not touch circuit components inside the equipment.

• Use a static-safe workstation, if available.

• Store the equipment in appropriate static-safe packaging when not in use.

Remove Power

WARNING: When you insert or remove the module while backplane

power is on, an electrical arc can occur. This could cause an explosion in hazardous location installations.

Be sure that power is removed or the area is nonhazardous before proceeding. Repeated electrical arcing causes excessive wear to contacts on both the module and its mating connector. Worn contacts may create electrical resistance that can affect module operation.

NOTE: All dimensions are in mm (in.). Hole spacing tolerance: ±0.4 mm (0.016 in.)

Maintain spacing from enclosure walls, wireways, and adjacent equipment. Allow 50 mm (2 in.) of space on all sides for adequate ventilation, as shown.

Panel Mounting

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.

Panel Mounting Using the Dimensional Template

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.

TIP

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.

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

TIP

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).

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).

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.

• 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.
