Emerson Ovation 5X00119G01 8-Channel RTD Input Module
5X00119G01 is an 8-channel RTD temperature acquisition module under Emerson Ovation DCS platform, originally Westinghouse legacy product. It collects resistance signals from three-wire RTD temperature sensors, converts resistance variation into standardized digital temperature data, and transmits processed signals to Ovation controller for furnace, pipeline and equipment temperature closed-loop monitoring.

This plug-in rack module features complete electrical isolation, high measurement accuracy and built-in channel fault diagnosis. It supports hot-swap replacement in redundant rack configuration without system shutdown, widely used as spare part for thermal power, nuclear power and petrochemical DCS cabinet maintenance and system retrofitting projects.
