Product Description
The Allen-Bradley 1746-IA16/C is a digital AC input module from the SLC 500 family, providing 16 channels to monitor 100–120 V AC signals from field devices such as push buttons, limit switches, pilot lights, and sensors.
Installed in an SLC 500 chassis, it communicates with the processor via the backplane. The “/C” revision indicates updated hardware and firmware for improved reliability and compatibility with modern SLC 500 controllers.
Ideal for manufacturing, process control, and machine automation, the 1746-IA16/C ensures precise signal monitoring while simplifying wiring with its removable screw-clamp terminal block. Although discontinued by the manufacturer, Radwell provides a 2-year warranty, making it suitable for legacy system maintenance and spare part needs.
