Allen-Bradley 1734-IE4C 4-Point Analog Input Module

The Allen-Bradley 1734-IE4C is a 4-channel analog current input module for POINT I/O distributed control systems, delivering high-resolution input for 4–20 mA field devices and enabling seamless integration of transmitters and process instruments into EtherNet/IP and other POINT I/O networks. It provides 16-bit resolution with delta-sigma conversion on four single-ended channels, supporting input ranges of 0–20 mA and 4–20 mA, and it uses a 24V DC backplane power requirement. Typically mounted on a DIN rail in machine-mounted I/O stations, process skids, packaging lines, or automated production environments, it interfaces 4–20 mA field devices such as pressure transmitters, flow meters, level sensors, and temperature transmitters with POINT I/O systems. Maintenance teams and system integrators rely on it for remote I/O expansion, upgrades, and retrofit applications, with common replacements including Allen-Bradley 1734-IE2C, 1734-IE8C, and 1769-IF4.
