Compact™ 1769-OF2 (Series B or Later) 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).
Compact™ 1769-OF2 (Series B or Later) Analog Output Module 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.
Compact™ 1769-OF2 (Series B or Later) Analog Output Module 5 1. Disconnect power. 2. Check that the bus lever of the module to be installed is in the unlocked (fully right) position. 3. Use the upper and lower tongue-and-groove slots (1) to secure the modules together (or to a controller). 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).
Compact™ 1769-OF2 (Series B or Later) Analog Output Module 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 End Cap Compact I/O Compact I/O Compact I/O Host Controller Side Compact I/O Top Compact I/O Maintain spacing from enclosure walls, wireways, adjacent equipment, etc.
Compact™ 1769-OF2 (Series B or Later) Analog Output Module 7 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.
Compact™ 1769-OF2 (Series B or Later) Analog Output Module 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 4. 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.
Compact™ 1769-OF2 (Series B or Later) Analog Output Module 9 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.
Compact™ 1769-OF2 (Series B or Later) Analog Output Module External Power Switch The 1769-OF2 (Series B or later) 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 in the up position (default), 24V dc power is drawn from the 1769 system power supply via the 1769 I/O bus.

(2) Series B and later modules provide this option.
Compact™ 1769-OF2 (Series B or Later) Analog Output Module 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. NOTE The terminal screws are non-captive.
Compact™ 1769-OF2 (Series B or Later) Analog Output Module 13 Wire Size and Terminal Screw Torque Each terminal accepts up to two wires with the following restrictions: Wire Type Wire Size Terminal Screw Torque Retaining Screw Torque Solid Cu-90°C (194°F) #14 to #22 AWG 0.68 Nm (6 in-lbs) 0.46 Nm (4.1 in-lbs) Stranded Cu-90°C (194°F) #16 to #22 AWG 0.68 Nm (6 in-lbs) 0.46 Nm (4.
Compact™ 1769-OF2 (Series B or Later) Analog Output Module Input Data File For each module, slot x, input data file words 2-3 contain the state of the module’s output data (output data echo) file words 0-1. During normal operation, these input words represent the analog values that the outputs are directed to by the control program.
Compact™ 1769-OF2 (Series B or Later) Analog Output Module 15 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.
Compact™ 1769-OF2 (Series B or Later) Analog Output Module Channel Configuration Words Words 0 through 1 of the configuration file allow you to change the parameters of each channel independently. For example, word 0 corresponds to channel 0.
