1794-IE8H | Allen-Bradley FLEX I/O Analog Input Module
The 1794-IE8H is an 8-channel single-ended analog input module designed for the Allen-Bradley FLEX I/O platform. It converts analog current or voltage signals into digital values for industrial PLC systems while supporting Highway Addressable Remote Transducer (HART) communication protocol for field device diagnostic and configuration data pass-through.
HART-Enabled Analog Signal Processing
Each of the eight single-ended channels independently processes analog field signals while maintaining continuous HART data access. The module acts as a HART master, routing intelligent field instrument data—such as secondary variables and device health diagnostics—directly to the control system over standard two-wire loops.
Mounting and Enclosure Specifications
The module features an open-style, DIN-rail mounted construction rated at IP20 protection. Designed to snap directly into compatible 1794 terminal base units, it provides a compact footprint for control panels while supporting system backplane communication via the FLEX I/O bus.
