1734-IE4C 4-Channel Analog Input Module 4-20mA | Allen-Bradley

The Original New Allen-Bradley 1734-IE4C 4-Channel Analog Current Input Module is a POINT I/O high-density analog input device designed for precise current signal acquisition in distributed industrial automation systems. Featuring four single-ended, non-isolated input channels with Delta-Sigma conversion technology, this module provides reliable monitoring of 4-20 mA or 0-20 mA signals from pressure transmitters, flow meters, level sensors, and other process instruments. Fully compatible with POINT I/O communication adapters and Rockwell Automation controllers.

Core Engineering Highlights:
4-channel 4-20mA / 0-20mA analog current inputs | 16-bit resolution (0.32 µA/count) | Delta-Sigma conversion | 0.1% accuracy @ 25°C | 0.55W power dissipation | 2.0 BTU/hr thermal dissipation | 4 set-points per channel alarming | Keyswitch position 3 | -20°C to +55°C operating temperature
