الوصف
The GE DS200TBQCG1A Analog Input Milliamp I/O Termination Module is a crucial printed circuit board (PCB) component of the General Electric Mark V Speedtronic Turbine Control System.1 Its primary role is to serve as the interface and termination point for various analog signals in turbine control applications.2 ⚙️
It is often referred to by its functional acronym TBQC (Termination Board, Quartz Crystal Reference).3
Function and Application
- Primary Function: The DS200TBQCG1A’s main function is signal termination for analog inputs and outputs, ensuring clean and reliable data transmission between field devices and the main control processor.4
- System Compatibility: It is part of the Mark V turbine control series, which manages and controls gas, steam, and wind turbine automated drive assemblies.5
- Signal Handling: It specifically handles:
- Milliampere (mA) Input Signals (e.g., 4-20 mA): These current signals are commonly used by industrial sensors for temperature, pressure, flow, etc.6
- LVDT/R Position Input Signals: Signals from Linear Variable Differential Transformer (LVDT) or Rotary Variable Differential Transformer (RVDT) sensors, which provide critical position feedback for valve and actuator control.7
- Milliampere (mA) Output Signals: For driving analog output devices.
- Milliampere (mA) Input Signals (e.g., 4-20 mA): These current signals are commonly used by industrial sensors for temperature, pressure, flow, etc.6
- Core Connectivity: It connects the terminated field signals to the TCQA (Turbine Control, Qualification, and Acquisition) board in the respective control core.8
Technical Details
| Feature | Specification / Detail |
| Series | GE Mark V (DS200 Series) |
| Functional Acronym | TBQC |
| Installation Position | Typically located at position 9 in the R1, R2, and R3 control cores. |
| Terminal Capacity | 2 Terminal Blocks (labeled TB1 and TB2) with 83 terminals each, for a total of 166 signal wire connections. |
| Configurability | Includes approximately 15 jumpers (BJ1 to BJ17 total) used for various configurations, such as: |
| – Connecting milliamp inputs to DCOM (Digital Common). | |
| – Selecting the maximum current output range (e.g., 20 mA or 200 mA) for milliamp outputs. | |
| Main Connectors | Features multiple connectors (e.g., JBR, JFR, three 40-pin, and three 34-pin) to interface with the TCQA board. |
| Signal Direction | The JBR connector typically handles the 4-20 mA input signals and reads the milliamp output signals to/from the TCQA board. The JFR connector handles the LVDT/R position input signals. |
The “A” in the part number DS200TBQCG1A indicates a specific functional revision of the base DS200TBQCG1 board.9
