1C31181G01 Emerson Ovation Remote I/O Master Unit

Product Overview

The 1C31181G01 is Emerson Ovation Remote I/O Master Unit (MAU, also known as Personality Module) for Ovation Distributed Control System (DCS), previously Westinghouse Ovation hardware. This communication module serves as a high-speed data bridge between the Ovation main controller and distributed remote I/O nodes, extending the DCS signal coverage to remote plant areas.

Equipped with RJ45 copper Ethernet interface and built-in galvanic isolation, the 1C31181G01 ensures stable and reliable data transmission even under harsh industrial electromagnetic interference. It supports hot swap replacement to reduce downtime during on-site maintenance, widely used as critical spare communication hardware for Ovation DCS system retrofit and maintenance projects.
