Allen-Bradley 1746-0A16 Output Module

The Allen-Bradley 1746-OA16 is a 16-point AC output module for the SLC 500 PLC family that provides discrete, triac-based outputs to switch AC loads. It is rated for 100/240 VAC loads and connects to the SLC 500 backplane, enabling 16 independently addressable outputs to drive devices such as relays, contactors, indicators, or other AC actuators from a single controller. Designed for use in standard SLC 500 installations, it aligns with the system’s I/O addressing and wiring conventions and is typically programmed with Rockwell Automation software such as RSLogix 500. Typical applications include lighting control, motor starter circuits, conveyors, and other automation tasks where AC loads must be switched from a PLC. As part of the 1746 I/O family, the OA16 integrates with conventional field wiring practices and supports scalable automation on mid-volume control panels that rely on multiple AC switching channels.
