The Allen-Bradley 1746-OAP12 is a high-current output module designed for the SLC 500 programmable logic controller system. This 12-point AC output module provides reliable switching for industrial applications requiring 120V or 240V AC control signals. Although the manufacturer discontinued this model on December 31, 2015, it remains a critical component for maintaining legacy SLC 500 automation platforms.
Features
High-current output capability for demanding industrial loads.
12 independent output points.
Wide operating voltage range from 85 to 264 VAC.
Compatible with standard SLC 500 I/O chassis configurations.

Installation Guidelines
Ensure the SLC 500 chassis power is disconnected before installing or removing the module.
Handle the module by the edges to prevent electrostatic discharge (ESD) damage to internal components.
Align the module carefully with the chassis slot guides and seat it firmly into the backplane connector.
Secure the module using the top and bottom retaining screws to ensure proper grounding and mechanical stability.
Verify that all field wiring is routed away from high-voltage AC lines or sources of electromagnetic interference (EMI) to maintain signal integrity.
