The Allen-Bradley 1747-OW16 is a 16-channel relay output module designed for the SLC 500 family and mounts in a 1747-series backplane. It provides isolated relay contacts to switch external loads under PLC control, enabling applications such as lighting, valve actuation, and motor control signals in industrial automation. This module occupies a single slot in the SLC 500 chassis and works with compatible Allen-Bradley processors to expand discrete output capability.
