Allen-Bradley 1746-OA16 is a 16-channel AC output module for Rockwell Automation's SLC 500 PLC systems. Each of the 16 outputs uses a triac to switch 100–240 VAC loads, with a per-channel current rating of up to 0.5 A, enabling direct control of light loads, relays, and small AC devices from a compatible SLC 500 rack. The module plugs into an SLC 500 I/O rack and is managed by a compatible CPU, making it suitable for compact automation tasks that require distributed AC switch control within a single rack.
