Description
Woodward PROTECH-SX 8237-1242
Technical Specifications
- Part Number: 8237-1242.
- Series: ProTech-SX.
- Safety Level: Designed to meet functional safety requirements for turbine protection.
Functional Features
- Overspeed Detection: Accurately monitors rotor speed to prevent catastrophic mechanical failure.
- Over-Acceleration Monitoring: Detects rapid increases in speed indicative of load rejection or control failure.
- Self-Diagnostics: Continuously monitors internal health and sensor integrity.
Application Scenarios
Deployed in industrial gas turbines, steam turbines, and mechanical drive applications requiring dedicated safety protection.
Performance Parameters
- Reliability: High Mean Time Between Dangerous Failures (MTTFd).
- Trip Response: Fast-acting relay outputs for immediate valve closure.
Material Composition
Ruggedized industrial components designed for continuous operation in demanding plant environments.
Structural Characteristics
Compact safety module with dedicated sensor inputs and relay outputs, designed for panel mounting.
Working Principle
Receives signals from speed sensors, compares them against predefined safety setpoints, and actuates trip relays when unsafe conditions are detected.
Installation Requirements
Install in a clean, climate-controlled control panel. Ensure proper separation between safety wiring and high-voltage power cables.
Precautions for Use
Perform regular proof testing as recommended by the safety manual to maintain the required Safety Integrity Level (SIL).
