SLC 500 AC Input Module 1746-IM16 by Allen-Bradley

Product Overview

The Allen-Bradley 1746-IM16 is a discrete AC input module for the SLC 500 platform. It offers sixteen input channels. Each channel accepts 170-265 Volts AC at 47-63 Hertz. This module fits into any SLC 500 chassis. It works in local, expansion, or distributed I/O racks. The backplane draws only 85 milliamps at 5 Volts DC. Signal delays are 35 ms for ON and 45 ms for OFF. This ensures accurate signal processing.

Application Scenarios

Use the 1746-IM16 for high-voltage AC sensing. It connects to push buttons, limit switches, and proximity sensors. It works well in industrial automation for motor control. It suits packaging, material handling, and process control. The module handles 200-240V AC signals from field devices. It is ideal for factory floors and heavy machinery.
