Description
GE IS200TBCIH1B
Technical Specifications
- System: Speedtronic Mark VI / Mark VIe.
- Board Type: Turbine Base Control / Interface Board.
- I/O Capacity: High-density terminal connections for turbine sensors and actuators.
Functional Features
- Turbine Protection: Monitors critical parameters like speed, temperature, and vibration to trigger emergency shutdowns if limits are exceeded.
- Control Logic Execution: Processes turbine startup, synchronization, and load-sharing sequences.
- Redundancy Support: Designed to operate in triple-modular-redundant (TMR) configurations for maximum reliability.
Application Scenarios
Exclusively used in power generation plants utilizing GE gas or steam turbines.
Performance Parameters
- Reliability: SIL-3 rated safety integrity level for critical protection functions.
- Response Time: Millisecond-level processing for emergency trip signals.
Material Composition
- PCB: High-Tg, flame-retardant industrial printed circuit board.
- Coating: Heavy-duty conformal coating to protect against harsh power plant environments (humidity, sulfur, vibration).
Structural Characteristics
- Form Factor: Standard Speedtronic board size with front-panel status LEDs and test points.
- Connections: Rear-mounted high-density connectors interfacing with the I/O terminal boards.
Working Principle
Receives real-time sensor data from the turbine, processes this data through redundant voting logic, and sends precise control signals to fuel valves, actuators, and protection relays to maintain optimal turbine operation.
Installation Requirements
- Must be installed in the correct slot within the Mark VI/VII 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.
