Allen-Bradley 1746-OA16 16-Point 120/240 VAC Output Module

Allen-Bradley 1746-OA16 is a 16-channel AC output module for the SLC 500 controller family, designed to switch general‑purpose loads on 120/240 VAC. It provides 16 discrete AC outputs (triac‑based) with an operating voltage range of 85–265 VAC at 47–63 Hz and a voltage category of 120/240 VAC, making it suitable for equipment such as relays, contactors, and indicator devices driven from an SLC 500 backplane. The module draws about 370 mA from the 5 V backplane, and it integrates with the standard 1746 backplane for easy rack mounting in Rockwell automation systems. As a legacy SLC‑500 I/O option, the 1746-OA16 is designed to extend discrete control to AC loads across multiple outputs from a single processor, preserving familiar wiring and mounting conventions within a compact 16‑point package.
