The GE IS200TBQBH2A is a Fixed Analog Input Terminal Board for the GE Mark V (MKV) and Mark VI (MKVI) turbine control systems. The <R> in the name indicates compatibility with a specific rack or cabinet design.
Function and Purpose ⚙️
The IS200TBQBH2A acts as the crucial interface between the turbine’s sensors and the main control processor. It receives continuous, or analog, signals (like those for temperature, pressure, and flow) and routes them to the system’s I/O packs. The board provides a secure, organized, and fixed connection point for the wiring from these sensors. The “Fixed” designation means the board is permanently mounted within the cabinet, which provides a highly stable and secure connection, ideal for applications in high-vibration or harsh environments. It also contains crucial circuitry for signal conditioning, which is essential for ensuring accurate data from the analog sensors.
Related Components 🤝
The IS200TBQBH2A works in conjunction with other components of the Mark V and VI systems:
- I/O Packs: These electronic modules, such as the TBA series, mount directly on the terminal board and contain the active electronics for converting the analog signal into a digital format that the main processor can use.
- Processor Cards: The main CPU of the system, which reads the digitized data from the I/O packs.
- Analog Field Devices: The board connects to a variety of analog sensors, such as pressure transmitters and current transducers.
