The Allen-Bradley 1746-OV16 is a 16-channel DC output module for the SLC 500 PLC family that provides current-sinking outputs. Operating over a 10–50 V DC range, each of the 16 points can switch DC loads such as relays, contactors, or indicator lamps when driven from a compatible 1746 backplane. It mounts in an SLC 500 chassis and interfaces with the 1746-series backplane, making it a straightforward expansion for discrete control of industrial equipment. This module is designed for digital control applications where sinking outputs are required to switch DC loads in automation systems.
