The GE DS200TBCBG1A is an RTD/Analog Input Terminal Board for the Mark V Speedtronic turbine control system. It’s a versatile I/O board that provides the physical connection and signal conditioning for both Resistance Temperature Detectors (RTDs) and other general-purpose analog input signals.
Technical Breakdown 🧠
The board’s function is to provide a reliable and accurate interface for a variety of field sensors, acting as a crucial link between the turbine’s physical environment and the control system’s digital logic. Its key functions include:
- RTD Interface: The board is designed to interface directly with RTD sensors, which are highly accurate temperature measurement devices. The board provides a constant current excitation source and measures the change in resistance of the RTD element to derive a precise temperature reading. RTDs are often used for applications requiring higher accuracy and stability than thermocouples.
- Analog Input Capability: In addition to RTDs, the DS200TBCBG1A also accepts and conditions other standard analog signals, such as 4-20 mA current loops and 0-10 VDC voltage signals. This makes the board a multi-purpose input module capable of monitoring a wide range of process variables, including pressure, flow, level, and valve position.
- Signal Conditioning: The card performs essential signal conditioning to ensure data integrity. This includes noise filtering to eliminate electrical interference and signal scaling to convert the raw sensor signal into a format usable by the Mark V’s main processor.
By combining temperature and general-purpose analog inputs on a single board, the DS200TBCBG1A offers a flexible and robust solution for comprehensive monitoring of turbine and plant auxiliary systems.
