Allen Bradley 1746-IM16 — Comprehensive Technical Overview
1. Product Introduction
The Allen Bradley 1746-IM16 is a digital AC input module designed for modular PLC systems, specifically intended for medium-voltage AC signal detection. It is used to interface field devices such as push buttons, limit switches, and control relays that operate at lower AC voltage levels compared to standard 120V modules.
This module provides 16 discrete input channels and is optimized for applications using 220–240V AC input signals. It converts field-level AC signals into logic signals that can be processed by the controller, ensuring accurate monitoring of machine and process conditions.
Installed in a chassis-based system, the 1746-IM16 communicates with the processor via the backplane, offering reliable signal transmission and integration into industrial automation systems.
