Description
Product Description
The 1746-IA16 by Allen-Bradley is a 16-channel AC digital input module developed for the SLC 500 programmable controller platform. Designed for reliable signal acquisition in industrial control systems, this module accepts 100/120V AC discrete input signals from field devices such as pushbuttons, selector switches, auxiliary contacts, and sensors.
Built for rack-mounted SLC 500 systems, the module integrates directly into the chassis backplane and provides LED-based channel diagnostics for fast troubleshooting and commissioning. The removable terminal block design simplifies wiring maintenance and replacement procedures in production environments.
The Allen-Bradley 1746-IA16 is commonly used in manufacturing lines, material handling systems, process automation cabinets, and machine control applications where stable AC input monitoring is required.
