Accurate and Reliable Process Signal Acquisition
The Ovation 1C31224G02 Analog Input Module is a precision field interface designed for Emerson Ovation Distributed Control Systems (DCS). It provides high‑fidelity conversion of analog signals from field instruments—such as transmitters, sensors, and other process devices—into digital data that the control system can monitor and act upon.
With robust signal conditioning, electrical isolation, and standard rack integration, this module is ideal for industrial environments where reliable and accurate analog input is critical to performance and safety.
