Allen-Bradley POINT I/O 1734-IR2E RTD Temperature Input Module

Product Description

The Allen-Bradley 1734-IR2E is a POINT I/O analog input module from Rockwell Automation’s Bulletin 1734 family, designed for high-accuracy temperature measurement. It provides two isolated channels for RTD (Resistance Temperature Detector) or other resistance-based sensors, allowing precise monitoring of process temperatures and resistance values.

Compact and DIN-rail mountable, the 1734-IR2E integrates seamlessly into distributed I/O systems, reducing wiring complexity and supporting scalable automation architectures via POINT I/O adapters. It is ideal for chemical processing, food & beverage, power generation, and pharmaceutical applications where precision and reliability are critical.
