The Allen-Bradley 1746-OA16 is a 16-channel AC output module for SLC 500 controllers that uses triac switches to drive line-voltage loads. It supports 120–240V AC loads with a maximum of 0.5 A per channel, making it suitable for controlling solenoids, relays, and small motors from an SLC 500 rack. This Series A module ships without a terminal strip and integrates into a standard 1746 backplane to work with compatible SLC 500 processors.
