1C31194G01 Emerson Ovation Valve Positioner Module

Product Overview

The 1C31194G01 is a high-precision valve positioner control module made by Emerson for the Ovation Distributed Control System (DCS), originally developed under Westinghouse Ovation hardware series. This specialized control module converts digital commands from the Ovation controller into drive signals for pneumatic or electro-hydraulic valve actuators. It receives real-time valve position feedback via LVDT sensors to realize closed-loop valve positioning for critical process control loops.

The 1C31194G01 comes with built-in galvanic isolation to protect the DCS rack from electrical noise, surges and ground loop interference in power plant environments. It integrates comprehensive channel diagnostics and LED status indicators for fast fault identification, widely used for boiler and turbine valve control, system retrofit and spare part replacement in power generation plants.
