The GE DS200TBQCG1B is an Analog Input Milliamp I/O Termination Module (often referred to as an RST Analog Termination Board) used in the General Electric Mark V Speedtronic Turbine Control System.
Its primary function is to provide the physical interface for field wiring, connecting the turbine’s analog sensors and devices to the main control electronics.
Key Functions
The DS200TBQCG1B board’s main role is to facilitate the termination and routing of critical analog signals within the triple-redundant (RST) control system architecture:
- Analog Input Termination: It is the direct connection point for field devices that communicate using milliamp current loops, typically 4-20 mA for process variables (like pressure, flow, and temperature).
- LVDT/R Position Input: It also terminates the inputs from LVDT (Linear Variable Differential Transformer) or LVDT/R (Rotary) sensors, which are used to monitor the precise position of turbine valves and actuators.
- Milliamp Output Termination: The board provides connection points for milliamp output signals, which are typically used to drive remote instrumentation or auxiliary monitoring systems. These outputs can be configured for a maximum range of either 20 mA or 200 mA via onboard jumpers.
- Interface to TCQA Board: The termination module connects directly to the TCQA (Turbine Control, Qualification, and Acquisition) board in its respective control core (R1, R2, or R3), transferring the terminated analog signals for processing and voting.
Context and Components
- System: The board is part of the DS200 Series components for the GE Mark V control system, which manages and protects gas, steam, and wind turbines.
- Location: The TBQC boards are typically located at position 9 in each of the redundant R, S, and T cores of the Mark V panel.
- Physical Connections: The board features large terminal blocks for connecting the hundreds of field wires. Ribbon cable connectors are used to interface with the main TCQA control board.
- Revision: The suffix G1B indicates a specific version or revision of the base TBQC board design. Different revisions (e.g., G1A, G1B, G1ABB) often represent minor circuit layout changes, component updates, or bug fixes, but maintain the same core function within the control system.
