Product Overview
The Ovation 1C31129G01 Analog Output Module is a highly reliable and precise component designed for use in Emerson Ovation Distributed Control Systems (DCS). It is engineered to provide analog output signals that interface with field devices such as control valves, dampers, actuators, and other process equipment in various industrial automation settings.
Capable of generating accurate analog outputs — typically 4–20 mA signals — the module allows the Ovation DCS to exert fine control over critical process variables such as flow, temperature, pressure, and chemical dosing. The 1C31129G01 delivers excellent signal integrity, wide operational temperature range, and robust construction, making it suitable for harsh industrial environments.
As part of the Ovation control architecture, this analog output module integrates seamlessly with other I/O components, CPUs, and networked systems, contributing to the overall reliability, flexibility, and performance of the plant’s automation platform.
