Overview
The DS200TCEAG1BRE is an Emergency Overspeed Board manufactured by General Electric for the Mark V Speedtronic gas turbine control system. It monitors overspeed and flame detection trip conditions and initiates a shutdown when the relevant trip conditions occur. The board includes an 80196 microprocessor, programmable read-only memory (PROM) modules, three fuses, 30 jumpers, and two bayonet connectors.

Monitoring and Shutdown Functions
The DS200TCEAG1BRE monitors overspeed and flame detection trip conditions within the Mark V control system. When the monitored conditions indicate a trip requirement, the board initiates the appropriate shutdown response.
Furthermore, the 80196 microprocessor processes the board’s programmed control functions. The PROM modules provide stored program information, while the 30 jumpers configure the board for its designated position in the P-core.
Board Connections and Configuration
The board uses two bayonet connectors to connect with other drive components and control boards. These connectors provide the electrical connection between the board and the associated system wiring.
In addition, the 30 berg jumpers support board configuration. Their settings determine the board’s designated location within the P-core. Therefore, maintenance personnel should check the jumper arrangement before replacing the board to ensure that the replacement matches the original configuration.
