The Allen-Bradley 1746-IN16 is a 16-point discrete input module for the SLC 500 I/O backplane, delivering sixteen sinking input channels that accept 24 V AC or DC signals. With a single common per module, it is designed to interface with sensors such as pushbuttons, limit switches, and proximity sensors, converting real‑world digital states into PLC‑readable logic. As part of the 1746 I/O family, it mounts in a 1746 chassis and communicates with a compatible SLC 500 controller via the backplane, making it a reliable choice for multi‑point digital input needs in industrial automation.
