1734-IE2C 2-Channel Analog Input Module 4-20mA | Allen-Bradley

The Original New Allen-Bradley 1734-IE2C 2-Channel Analog Current Input Module is a POINT I/O analog input device designed for precise 4-20 mA and 0-20 mA signal acquisition in distributed industrial automation systems. Featuring two single-ended, non-isolated input channels with Delta-Sigma conversion technology, this module provides reliable monitoring of current signals from pressure transmitters, flow meters, level sensors, and other process instruments. Factory calibrated with 16-bit resolution and 0.1% accuracy, it delivers high-precision measurement without requiring field calibration. Fully compatible with POINT I/O communication adapters and Rockwell Automation controllers.
