Technical Specifications and Board Design
This simplex trip board provides protection and control for GE Mark V turbine systems. The GE DS200TCTGG1A DS200TCTGG1AFF monitors critical parameters and initiates safe shutdowns. You can install this board into the standard Mark V turbine control rack. Its rugged design handles extreme temperature variations inside turbine cabinets. The board weighs approximately 0.68 kilograms. Its dimensions measure 28 cm in height, 18 cm in width, and 2.5 cm in depth.

Trip Functionality and Protection Features
The board initiates a turbine trip when it detects dangerous operating conditions. Each of the six trip relays connects to a separate shutdown circuit. The GE DS200TCTGG1A DS200TCTGG1AFF monitors overspeed, overtemperature, and vibration exceedances. It also responds to external emergency stop signals from pushbuttons. The board latches the trip condition until you manually reset it. A front-panel LED indicates which condition caused the most recent trip. The trip logic operates independently from the main turbine controller.
Input Monitoring and Signal Processing
Sixteen discrete inputs receive status signals from field sensors and switches. Four analog inputs monitor temperature, pressure, or vibration transducers. The GE DS200TCTGG1A DS200TCTGG1AFF compares all analog values against programmable trip setpoints. Exceeding any setpoint triggers the corresponding trip relay immediately. The optocoupler inputs provide complete electrical isolation from field wiring. Consequently, lightning or ground faults will not damage the board. Each input includes a green LED for visual status confirmation.
Installation and Operational Guidelines
You must insert this board into a dedicated slot in the Mark V rack. The backplane supplies 5V and 24V DC power to the board automatically. The GE DS200TCTGG1A DS200TCTGG1AFF draws approximately 300 mA from the 5V supply rail. It stores no trip history or configuration data independently. Therefore, the turbine controller retains all setpoints and event logs separately. You should inspect the gold edge connector for oxidation before installation. Clean it with isopropyl alcohol and a soft lint-free cloth only. The board requires no external battery for normal trip protection operation.
