Allen-Bradley 1794-IE8

The Allen Bradley 1794-IE8H is an 8-channel HART-enabled analog input module from the Flex I/O product family. Its core function is to acquire analog signals from field devices—such as pressure, temperature, and flow transmitters—and simultaneously read digital HART (Highway Addressable Remote Transducer) data, enabling both process monitoring and intelligent device diagnostics through a single wiring infrastructure.

The Allen‑Bradley 1794‑IE8 is an 8‑channel analog input module from the Bulletin 1794 FLEX™ I/O system, designed for applications requiring reliable and precise analog signal acquisition. It supports single‑ended current and voltage inputs, making it ideal for interfacing with field transmitters, analog instruments, recorders, and process loop controllers . As part of the distributed FLEX I/O architecture, this module works with a communication adapter and terminal base to provide flexible, space‑efficient I/O placement close to field devices.
