Allen-Bradley 1746-IA16 16-Channel 120V AC Input Module

Allen-Bradley 1746-IA16 is a SLC 500 16-channel input module that accepts 120V AC field signals from devices such as pushbuttons, limit switches, proximity sensors, and other control devices, and feeds them into a Rockwell Automation SLC 500 controller for deterministic, real-time logic and sequencing. Designed for 100/120V AC inputs operating at 50/60 Hz, the 1746-IA16 provides sixteen discrete input points with wiring arranged for straightforward field connections and supports typical AC control circuits used in manufacturing environments. As part of the 1746 I/O family, it mounts in a compatible 1746 I/O backplane chassis, shares the backplane power and data bus with other modules, and communicates with the CPU via the standard SLC/1746 backplane interface to deliver reliable scan times. Typical applications span automation panels, conveyors, presses, and process lines where 120V AC field devices signal the PLC, making this module a common retrofit option for legacy equipment and a foundational component of SLC 500 control architectures.
