Allen-Bradley 1746-IO8 SLC 500 Digital I/O Module

Product Overview

The Allen-Bradley 1746-IO8 is a digital I/O combination module for the SLC 500 system. It fits into any slot except slot 0 of a 1746 I/O chassis. This module provides four 120V AC inputs and four relay contact outputs. It operates on 85-132V AC power. This makes it a flexible choice for many industrial control tasks.

Application Scenarios

This module works well in discrete manufacturing. It is ideal for packaging lines and material handling systems. Use it for simple machine control and monitoring. The 1746-IO8 handles both input sensing and output switching in one unit. It saves space in your control panel.

Technical Specifications

The 1746-IO8 has 4 input points and 4 output points. Inputs work with 120V AC signals. Outputs use relay contacts with a Normally Open (N.O.) form. Each output handles 1.5A continuous at 120V AC. Each output handles 1.2A continuous at 24V DC. Signal delay is 35-45 milliseconds for both ON and OFF states. The module draws 0.03A at 5V DC from the backplane. It draws 0.025A at 24V DC. Heat dissipation is 0.27W for all input points. Each output point dissipates 0.133W. Total heat dissipation is 3W. Operating temperature range is 0 to 60 °C. Non-operating temperature range is -40 to 85 °C. It has a shock rating of 30G. It handles vibration of 2.5G at 57-200Hz.

Installation & Maintenance Guide

Install the 1746-IO8 in any I/O slot except slot 0. Ensure the chassis power is off before insertion. Secure the module with the locking screws. Wire inputs according to the 120V AC source. Wire outputs to the load devices. Use proper fusing for output circuits. Keep the module free of dust and moisture. Check connections during routine maintenance.
