Installation Guidelines

Follow these steps to install the Allen-Bradley 1769-OW16 correctly into your system.

1. Ensure the controller assembly is completely powered off before installation.

2. Insert the Allen-Bradley 1769-OW16 into an adjacent Compact I/O slot.

3. Slide the module along the bus connector until it seats firmly.

4. Lock the bus levers to secure the mechanical connection.

5. Connect your field wiring to the removable terminal block.

6. Group One uses outputs 0 through 7. Group Two uses outputs 8 through 15.

This module requires its own power supply except when connected to a MicroLogix 1500 base. Maintain proper spacing from wireways and heat sources. Do not exceed 8 modules between this module and the power supply. Use copper wires with 90°C minimum insulation rating.
