Allen-Bradley 1734-IA2 Digital AC Input Module 2-Channel

Product Overview

The Allen-Bradley 1734-IA2 is a digital AC input module from the POINT I/O series. It features two input channels for 120 Volts AC signals. Each channel has a status indicator for easy troubleshooting. The module works with ControlNet, DeviceNet, and EtherNet/IP networks. Its compact form factor saves panel space. You can install it horizontally or vertically on a DIN rail. This module suits a wide range of industrial applications. It integrates seamlessly with Rockwell Automation PLCs.

Application Scenarios

Use this module in automotive, packaging, and material handling systems. It senses 120V AC signals from push buttons, limit switches, and sensors. The two channels handle simple on/off inputs for discrete control. It works well with CompactLogix and ControlLogix controllers. The module operates in harsh environments with reliable performance. It supports both new installations and upgrades of existing systems.
