Allen-Bradley 1734-IA2 POINT I/O 2-Channel AC Input Module

Technical Specifications

Product Overview

The Allen-Bradley 1734-IA2 is a compact 2-channel digital AC input module engineered for the Rockwell Automation POINT I/O system. Operating with a nominal input voltage of 120V AC (85 to 132V AC range), this ultra-thin 12 mm slice module accepts 120V AC signals from sensors and switches, routing discrete data to a ControlLogix or CompactLogix controller over EtherNet/IP, DeviceNet, or ControlNet backplanes. Weighing only 30.9 grams, it features channel status LEDs, 240V AC continuous isolation, and flexible mounting orientation.

Key Features

• 2-Channel Discrete AC Sensing: Provides two individual 120V AC inputs (Input 0 and Input 1) with individual status LEDs for real-time diagnostic visibility.
• High Dielectric Isolation Protection: Continuous 240V AC isolation rating tested to withstand up to 3250V DC for 60 seconds to protect control backplanes.
• Ultra-Compact Slice Footprint: Narrow 12 mm module width allows high-density DIN rail mounting in both vertical and horizontal configurations.
• Multi-Network Compatibility: Seamlessly integrates across EtherNet/IP, ControlNet, and DeviceNet architecture using standard POINT I/O adapters.

Installation Essentials

Snap module into POINT I/O terminal base. Set key switch position, wire 120V AC inputs, and ground DIN rail.
