The GE DS200TCEAG1B DS200TCEAG1BTF provides critical overspeed protection for Mark V turbine systems. This emergency board monitors turbine speed and initiates shutdown when exceeding safe limits. It features dual speed inputs for redundant overspeed detection. Weighing only 0.32 kg, the GE DS200TCEAG1B DS200TCEAG1BTF mounts inside Mark V control cabinets. Its dimensions measure 220 mm x 130 mm x 28 mm.
Speed Monitoring and Protection Features
The GE DS200TCEAG1B DS200TCEAG1BTF accepts magnetic pickup and proximity sensor inputs for speed measurement. This board provides two independent overspeed trip channels for redundant protection. Each channel features programmable trip setpoints from 100 RPM to 20,000 RPM. Moreover, the GE DS200TCEAG1B DS200TCEAG1BTF includes built-in self-test for continuous health monitoring. Consequently, you can verify protection functionality without taking the turbine offline.
Output and Diagnostic Features
The GE DS200TCEAG1B DS200TCEAG1BTF provides dedicated trip relay outputs for fuel and steam valve control. This board includes LED indicators for power, overspeed, and channel status. It features test points for speed signal verification during maintenance. The GE DS200TCEAG1B DS200TCEAG1BTF draws 200 mA from the 24 V DC power supply. Therefore, it operates reliably even during emergency power conditions.
