Description
GE DS3800NBIC
Technical Specifications
- Product Line: GE Speedtronic Mark IV.
- Board Type: Analog/Digital I/O or Signal Conditioning Board.
- Series Prefix: DS3800.
Functional Features
- Signal Processing: Conditions raw sensor signals (temperature, pressure, speed) for the main turbine controller.
- High Reliability: Triple Modular Redundancy (TMR) compatible architecture for fault tolerance.
- Diagnostics: Onboard LEDs for quick troubleshooting and status monitoring.
Application Scenarios
Exclusively used in power generation turbines, aerospace derivative gas turbines, and large-scale industrial prime movers.
Performance Parameters
- Response Time: Millisecond-level signal processing for real-time turbine protection.
- Noise Rejection: High immunity to electromagnetic interference (EMI) in power plant environments.
- Operating Temperature: Extended range for unconditioned turbine enclosure environments.
Material Composition
Multi-layer FR4 PCB with conformal coating to protect against moisture, sulfur, and conductive dust. Gold-plated backplane connectors.
Structural Characteristics
Standard Eurocard form factor with front panel test points, status LEDs, and precision edge connectors for backplane integration.
Working Principle
Receives analog and digital signals from field instruments, conditions them through filtering and amplification, and routes the processed data to the central Mark IV processor via the backplane.
Installation Requirements
Must be inserted into an active Mark IV rack. Handle by edges only to avoid damaging backplane pins.
Usage Precautions
Never insert or remove the board while the turbine control system is energized. Ensure proper grounding of the control rack.
