DS200TCEAG1B is an Emergency Overspeed Board and is part of the GE Speedtronic Mark V gas turbine control systems. One microprocessor and much programmable read-only memory (PROM) modules are included in the General Electric Emergency Overspeed Board type DS200TCEAG1B. Three fuses, 30 jumpers, and a pair of bayonet connections are also included. The board keeps an eye on the drive for over-speed and flame detection trip conditions and shuts it down as needed.
