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.\u003c\/p\u003e\n\u003ch3\u003eHART-Enabled Analog Signal Processing\u003c\/h3\u003e\n\u003cp\u003eEach 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.\u003c\/p\u003e\n\u003ch3\u003eMounting and Enclosure Specifications\u003c\/h3\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003e1794-IE8H\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eAllen-Bradley\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInputs\u003c\/td\u003e\n\u003ctd\u003e8 channels, single-ended\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSignal Range\u003c\/td\u003e\n\u003ctd\u003eCurrent or Voltage\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommunication\u003c\/td\u003e\n\u003ctd\u003eHART pass-through capable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEnclosure Rating\u003c\/td\u003e\n\u003ctd\u003eIP20 (Open-Style)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMounting\u003c\/td\u003e\n\u003ctd\u003eDIN Rail (via Terminal Base Unit)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.70 lbs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What field device communication protocol does the 1794-IE8H support alongside standard analog inputs?
