DS200QTBAG1A GE Mark V RST Terminal Board

Product Description

The DS200QTBAG1A is an RST Terminal Board manufactured by General Electric for the Speedtronic Mark V gas turbine control system. It provides signal termination and communication connections for turbine control circuits, including DTV excitation, servo inputs, pulse-rate inputs, and WATT/VAR transducer signals. Furthermore, the board contains IONET and COREBUS connections and interfaces with the TCQC board in the respective control cores.

Signal Termination and Communication

The DS200QTBAG1A provides screw terminal connections for multiple control and feedback signals. These connections allow field signals to reach the corresponding control electronics through the Mark V system architecture.

The board handles several signal groups, including:

• DTV excitation connections.
• Servo input signals.
• Pulse-rate input signals.
• WATT/VAR transducer inputs.
• IONET and COREBUS communication connections.

System Configuration

The QTBA terminal board occupies position L6 in the R, S, and T control cores. It terminates signals used by the TCQC board in the corresponding cores. Therefore, its position and signal connections should be checked against the installed Mark V control configuration when identifying a replacement board.

Signal Identification and Wiring Precautions

The terminal board supports connections for various turbine control signals. Examples include HP and LP magnetic pickups for speed measurement, flow-meter signals, water injection flow-meter inputs, servo valve outputs, T excitation, and W transducer signals.

Do not ground-short the LVDT excitation outputs. This restriction should be considered when inspecting wiring, troubleshooting signal faults, or performing maintenance on the terminal board.
