Description
GE IS205TFBHG1A
Technical Specifications
- System: Speedtronic Mark VI / Mark VIe.
- Board Type: Turbine Control / Interface Board.
- Function: Signal processing and control logic execution.
Functional Features
- Turbine Management: Processes sensor data to regulate fuel, air, and load.
- Safety Protection: Triggers alarms or emergency trips if parameters exceed safe thresholds.
- System Integration: Interfaces seamlessly with other Mark VI/VII boards via the backplane.
Application Scenarios
Exclusively used in power generation plants utilizing GE gas or steam turbines to prevent mechanical damage and ensure efficient power output.
Performance Parameters
- Reliability: SIL-rated safety integrity level for critical protection functions.
- Response Time: Millisecond-level processing for control and trip signals.
Material Composition
High-Tg, flame-retardant industrial printed circuit board with heavy-duty conformal coating.
Structural Characteristics
Standard Speedtronic board size with front-panel status LEDs and test points. Rear-mounted high-density connectors interface with the I/O terminal boards.
Working Principle
Receives conditioned signals from I/O terminal boards, executes control and protection logic, and transmits commands to actuators or upstream controllers via the system backplane.
Installation Requirements
Must be installed in the correct slot within the Mark VI rack. Requires strict adherence to GE’s wiring and grounding manuals.
Usage Precautions
Never modify board components or traces. Ensure all redundant channels are functioning before placing the turbine in service.
