Allen-Bradley 1746-OA16 AC Output Module 16-Point

Allen-Bradley 1746-OA16 is a 16-point AC output module for the SLC 500 PLC family that actively switches 85–265 VAC loads. Built for general-purpose control of line-voltage devices, it provides 16 outputs in a single module to drive AC-powered loads such as lighting, solenoids, and valves under PLC command. The module operates on 85–265 VAC at 47–63 Hz and draws about 370 mA from the 5 V backplane, aligning with typical SLC 500 backplane power budgets. As part of the Rockwell Automation SLC 500 I/O lineup, the OA16 is designed to mount in a compatible 1746 backplane chassis and integrate with the broader Rockwell ecosystem for PLC-based automation. For precise per-output current ratings, derating behavior, and wiring schemes, consult the official documentation and compatibility guides for your specific chassis and power supply.
