Allen-Bradley 1734-IE2C Two-Channel Analog Input Module

The Allen-Bradley 1734-IE2C is a two-channel analog current input module for POINT I/O distributed control systems, designed to monitor 4–20 mA field devices such as transmitters and sensors in remote I/O panels, process skids, water treatment facilities, and manufacturing lines. It provides two current inputs with ranges of 0–20 mA or 4–20 mA, 16‑bit resolution, and an input impedance of 250 ohms nominal to preserve signal integrity. The module draws 75 mA from the backplane at 5 V DC, requires 24 V DC field power, and offers channel-to-channel and system isolation to enhance safety and reliability. Mount it on a DIN rail and use compatible adapters such as 1734-AENT or 1734-AENTR; common replacements include 1734-IE4C, 1734-IE2V, and 1769-IF4.
