الوصف
The GE DS200TCCBG1B is an Expanded Analog Card for the Mark V turbine control system. Its primary purpose is to provide a high-density, versatile interface for a larger number of analog signals than a standard card, enabling more comprehensive monitoring and control in a single board. The TCCB
designation identifies it as an I/O TC2000 Analog Board, with the G1B
indicating a specific hardware revision.
Technical Breakdown 🧠
This card’s function is to serve as a versatile interface, bridging the gap between the analog signals of field devices and the digital logic of the Mark V controller.
- High-Density I/O: The “Expanded” designation means the board can handle a greater number of analog inputs and/or outputs than a standard “Common Analog” card. This is essential for complex turbine control applications that require monitoring and controlling a large number of parameters such as pressure, flow, vibration, and temperature.
- Versatile Analog Interface: The board provides signal conditioning for a wide range of standard analog signals, including 4-20 mA current loops, 0-1 mA inputs, and signals from RTDs (Resistance Temperature Detectors), and LVDTs (Linear Variable Differential Transformers). It can also handle generator and bus voltage inputs, as well as line current inputs, making it a powerful and flexible tool for power system monitoring.
- Signal Conditioning: The card performs essential signal conditioning to ensure data integrity and accuracy. This includes filtering out electrical noise, scaling the raw signal to a usable range, and providing a stable interface for sensitive field devices. The board also contains a microprocessor to manage these I/O functions.
