The Emerson 1C31116G01 is a high-accuracy Analog Input PMOD (Power Module) specifically engineered for the Ovation Distributed Control System (DCS). This module serves as a primary interface for digitizing continuous analog variables from field-mounted transmitters. It is designed to capture and process critical process data, such as flow rates, pressure levels, and temperature readings, providing the high-resolution feedback necessary for complex PID control loops and safety-related logic.
