1C31129G03 Emerson Ovation Analog Output Module

Product Overview

The 1C31129G03 is a high-precision analog output module manufactured by Emerson for the Ovation distributed control system (DCS), previously Westinghouse Ovation hardware. This AO module converts digital control signals from the Ovation controller into standard 4–20mA analog current signals to drive field actuators, control valve positioners, variable frequency drives and modulating pumps in process plants.

The 1C31129G03 adopts independent channel galvanic isolation design, which protects the DCS rack from ground loop noise, surge interference and electrical disturbance in harsh industrial cabinet environments. It supports reliable closed-loop control for critical process control loops in power and petrochemical facilities.
