The Emerson 1C31132G01 is a high-precision analog output module designed for the Emerson Ovation DCS. It converts digital control signals from the Ovation controller into proportional 4-20 mA analog currents, commonly used to control modulating valves, positioners, and variable speed drives. With eight independent channels in a compact form factor, the module is designed for high-density I/O configurations in power plants and water treatment facilities. It features galvanic isolation to protect against electrical transients and ensures long-term operational stability with minimal thermal drift.

The 1C31132G01 is used in applications such as steam turbine control, feedwater regulation, and chemical dosing systems. Its compact design makes it ideal for retrofitting legacy Westinghouse systems to modern Ovation DCS architectures, especially in situations where cabinet space is limited.
Can this card be used in a redundant configuration?
Yes, the 1C31132G01 is compatible with Ovation redundant I/O schemes. When paired with a redundant electronics base, the system can seamlessly switch between the primary and secondary cards without interrupting the 4-20 mA signal.
Does it support HART communication?
The 1C31132G01 is a standard analog output card. However, HART-compatible versions are available within the Ovation lineup. This specific model is designed for standard 4-20 mA current loop control.
What is the significance of the Westinghouse branding?
Many Ovation components carry the Westinghouse name due to the system's heritage. The 1C31132G01 is fully supported by Emerson Automation Solutions and is part of the current Ovation lifecycle.
