Allen-Bradley 1746-IM16 SLC 500 16-Point 240V AC Input Module

Product Description

The Allen-Bradley 1746-IM16 is a 16-point AC input module for the SLC 500 series, engineered to provide reliable signal acquisition from standard 240V AC sources. This module delivers precise input detection with minimal signal delay, making it suitable for general-purpose monitoring and control applications. Its compact design supports integration into SLC 500 racks using standard 1746-HT or 1746-HCA backplanes.

Built for industrial environments, the 1746-IM16 operates across a wide temperature and humidity range, and its low inrush current reduces stress on connected circuits. Step response and signal timing are optimized for fast and accurate logic execution.
