Product Overview
The 1794-IRT8XT is an Allen-Bradley FLEX I/O-XT analog input module for thermocouple, RTD, and millivolt signals. As the extended-temperature, conformally coated version of the 1794-IRT8, this module integrates into a FLEX I/O-XT chassis to acquire temperature data in control and monitoring applications such as machine and process temperature measurement. 1794-IRT8XT supports eight channels and is typically used in industrial environments subject to wide temperature ranges.
