Description
Woodward 9908-399
Technical Specifications
- Product Series: 9908 Series Digital Control.
- Processor: High-speed microprocessor for deterministic real-time control.
- I/O Interface: Supports a wide range of analog, digital, and RTD inputs.
- Communication: Serial/Ethernet interface for integration with plant DCS/SCADA.
Functional Features
- Real-Time Control: Executes speed, load, and temperature control loops with millisecond-level precision.
- Advanced Protection: Processes safety-critical logic for overspeed, over-temperature, and vibration shutdowns.
- Data Logging: Records operational trends and fault events for predictive maintenance.
- Programmable Logic: Highly configurable to adapt to various prime mover types and plant requirements.
Application Scenarios
Deployed in industrial gas turbines, steam turbines, and turbo-expanders requiring robust digital governing and protection.
Performance Parameters
- Scan Rate: Fast, deterministic scan rates for critical control loops.
- Reliability: High Mean Time Between Failures (MTBF) for continuous 24/7 operation.
Material Composition
Industrial-grade electronic components on multi-layer PCBs with protective conformal coating. Housed in a rugged, EMI-shielded metal enclosure.
Structural Characteristics
Compact, modular form factor designed for panel or rack mounting. Features front-panel status LEDs and diagnostic interfaces for easy troubleshooting.
Working Principle
Continuously samples turbine parameters via field sensors. The processor executes the user-defined control logic, making real-time decisions to adjust fuel valves, guide vanes, and other actuators to maintain safe and efficient operation.
Installation Requirements
Mount in a clean, dry, and climate-controlled enclosure. Ensure proper chassis grounding and use shielded cables for all field wiring.
Usage Precautions
- Always back up the configuration database before making online changes.
- Observe strict Electrostatic Discharge (ESD) precautions when handling.
- Verify firmware compatibility with other system components before upgrading.
