Product Description

The Allen-Bradley 1746-IA8 is a digital AC input module from the SLC 500 family, designed to monitor up to eight 100/120 V AC field devices. Each input detects the ON/OFF status of switches, sensors, and pilot lights, integrating directly with an SLC 500 chassis via the backplane for reliable control system operation.

This module is ideal for industrial applications where AC devices are common. Its rack-mountable design, removable screw-clamp terminal block, and robust electrical specifications make it suitable for machine control, process automation, and other discrete signal applications.

Although discontinued by the manufacturer, the 1746-IA8 remains supported through Radwell’s 2-year warranty, making it a dependable replacement or spare part for legacy SLC 500 systems.
