Description
GE IS210WSVOH1A
Technical Specifications
- System: Speedtronic Mark VI.
- Board Type: Servo Valve Output Board.
- I/O Capacity: Multiple isolated servo valve output channels.
Functional Features
- Precision Control: Generates highly accurate current or voltage signals for servo valve positioning.
- Feedback Monitoring: Continuously monitors LVDT feedback to ensure valve position matches command.
- Fault Protection: Detects open circuits, short circuits, and excessive valve travel.
Application Scenarios
Exclusively used in power generation plants utilizing GE Mark VI gas or steam turbine controls to manage fuel and steam admission.
Performance Parameters
- Accuracy: High-precision output with low ripple for smooth valve operation.
- Response Time: Fast signal processing for dynamic turbine control.
Material Composition
High-Tg, flame-retardant industrial PCB 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 I/O terminal boards.
Working Principle
Receives valve position commands from the primary turbine controller, generates the appropriate drive signal for the servo valve, and continuously compares LVDT feedback to correct any positioning errors.
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.
