The Allen-Bradley 1746-OA16 is a 16-point output module for the SLC 500 PLC system. It provides 16 discrete outputs driven by the SLC 500 backplane, enabling control of external devices such as relays, contactors, and solenoids in industrial automation. As part of the 1746 family, the 1746-OA16 installs in a compatible SLC 500 rack to expand the controller’s output capability.
