Allen-Bradley 1746-IO12DC PLC Module

Allen-Bradley 1746-IO12DC is a 12-point DC combination I/O module for the SLC 500 family, delivering twelve discrete digital I/O points that handle 24V DC control signals. The module plugs into the 1746 backplane and is addressed by an SLC 500 controller, enabling you to expand a panel’s digital input and output capabilities with a single card. It is designed for standard industrial automation environments and works alongside other 1746-series I/O to simplify wiring, panel layout, and maintenance. Typical applications include machine automation, packaging lines, conveyors, and process control where a compact, plug-in I/O solution is needed to monitor sensors such as proximity switches and pushbuttons while driving actuators like relays or solid-state devices, all within the same controller ecosystem.
