Description
Product Overview
ABB DSPU131 (3BSE000355R1) is the MA200 AT-bus interface board belonging to the ABB Advant Master legacy DCS platform. It acts as the communication gateway for the Advant Master control system, handling high-speed data transmission over AT-bus between controllers, I/O racks and operator nodes. Widely deployed in power plants, pulp & paper and chemical processing facilities, this long-discontinued board serves as critical aftermarket spare parts for maintenance and retrofit of existing Advant Master installations.
