Description
Woodward PROTECH203
Technical Specifications
- Series: ProTech 203.
- Sensor Inputs: Three independent magnetic pickup (MPU) inputs.
- Safety Level: SIL 3 capable.
- Outputs: Multiple redundant relay outputs.
Functional Features
- Triple Modular Redundancy: 2oo3 (2-out-of-3) voting logic for maximum safety and availability.
- High-Speed Protection: Reliable tripping at speeds exceeding 10,000 RPM.
- Self-Diagnostics: Continuous internal monitoring to detect sensor or module failures.
- Testability: Online testing capabilities without tripping the turbine.
Application Scenarios
Mandatory safety system for high-speed industrial turbines, turbo-compressors, and critical power generation equipment.
Performance Parameters
- Response Time: Extremely fast trip response.
- Accuracy: High-precision speed measurement.
Material Composition
High-reliability safety-grade electronic components.
Structural Characteristics
Rack-mounted or panel-mounted module with front-panel status and fault indicators.
Working Principle
Continuously compares the signals from three independent speed sensors. If two or more sensors indicate an overspeed condition, the system instantly de-energizes the trip relays to shut down the prime mover.
Installation Requirements
Install sensors with proper spacing and shielding. Wire the trip relays directly to the turbine shutdown solenoids.
Precautions for Use
Never bypass the ProTech 203 system. Conduct regular functional tests as required by safety regulations and site procedures.
