1746-IM4 Allen-Bradley SLC 500 AC Input Module 4 Points

Product Overview

The Allen-Bradley 1746-IM4 is a digital AC input module. It belongs to the SLC 500 family. This module has four input points. It works with 200-240V AC signals. The operational voltage range is 170-265V AC. It supports a line frequency of 47-63 Hz. The module draws 35 milliamps from the 5V DC backplane. It does not draw current from the 24V DC backplane. The 1746-IM4 offers reliable signal detection. It is ideal for general-purpose 125V DC input applications. The module provides circuit isolation at 1500V AC. This isolation protects the backplane from high voltages.

Application Scenarios

Use the 1746-IM4 in industrial automation systems. It works well for monitoring AC signals. Applications include motor start/stop detection. Use it for conveyor belt status monitoring. It fits in manufacturing and process control. The module suits environments with high electrical noise. It meets NEMA ICS 2-230 noise immunity standards. The 1746-IM4 is UL, CSA, and C-UL certified. These certifications allow use in hazardous locations. Install the module in a 1746 I/O chassis. It connects with 1746-HT and 1746-HCA cables. The module handles shock up to 30G. It handles vibration up to 2.5G at 57-500 Hz.
