Allen Bradley 1734-IR2E Input Module

The AB 1734-IR2E is a 2-channel analog input module designed for temperature sensing using resistance temperature detectors (RTDs) in POINT I/O systems. Operating at 24V DC, this module supports high-accuracy input from platinum RTDs (e.g., PT100, PT1000) and is ideal for temperature monitoring in distributed industrial control systems.

With a compact 12 mm width and plug-in terminal base design, the 1734-IR2E offers space-saving installation and reliable integration into Rockwell Automation’s POINT I/O architecture.
