Allen-Bradley 1746-OA16 is a 16-point AC output module designed for the SLC 500 PLC family. It provides 16 triac-based outputs for switching AC loads in 120/240 VAC control circuits, with isolation between field wiring and the backplane up to 500 V DC. The module plugs into a 1746 backplane and works with standard SLC 500 controllers, enabling compact control of multiple relays, contactors, or other AC-powered devices from a single module.
