Allen-Bradley 1734-IE2C/C Series C Analog Current Input

Product Description

The Allen-Bradley 1734-IE2C/C is a Series C POINT I/O analog current input module from Rockwell Automation’s Bulletin 1734 family. It is designed for accurate acquisition of industrial process signals from field devices such as pressure transmitters, flow meters, temperature sensors, and level instruments.

The 1734-IE2C/C provides two isolated 4–20 mA current input channels, enabling reliable measurement in electrically noisy environments while reducing the risk of ground loops. Revision C represents an updated hardware and firmware design compared to earlier revisions, offering improved stability, diagnostics, and compatibility with modern ControlLogix and CompactLogix platforms.

With its compact form factor and DIN-rail mounting, the module integrates easily into distributed I/O architectures, helping reduce wiring distance and simplify panel design. Series C modules are also conformal coated, providing additional protection in demanding industrial environments.
