The Allen-Bradley 1746-IO12 is a SLC 500 digital input/output combination module that provides six 120 V AC inputs and six 120 V AC relay outputs, designed to install in an open-style SLC 500 backplane. This 12-point module integrates with the SLC 500 I/O system to read 120 VAC sensor signals while switching external devices via six relay contacts, all within a compact form factor that plugs into the SLC 500 rack. Common applications include basic industrial automation tasks in small control panels and retrofit projects where simple 120 VAC signaling and control are required within the Rockwell Automation SLC 500 ecosystem.
