The Allen-Bradley 1746-OA16 is a 16-channel AC output module for the SLC 500 system that uses triac outputs to switch line-powered loads from 100 to 240 VAC. Each channel dissipates about 0.462 W, for a total module heat load of roughly 9.3 W. This 16-point output block is designed to control AC devices such as relays and contactors within a 1746 I/O rack in SLC 500 PLC deployments.
