Description
Woodward PROTECH-GII 8237-2601
Technical Specifications
- Part Number: 8237-2601.
- Power Input: High Voltage / High Voltage (HV/HV) configuration.
- Relay Output: Voted trip relays utilizing a 2oo3 architecture.
- Response Time: 12 milliseconds.
Functional Features
- Fault Tolerance: Each module is fully fault-isolated; a failure in one does not affect the others.
- Configuration Copy: Utilizes the internal CAN network to seamlessly copy configuration files between modules.
- Alarm Relays: Includes individual alarm relays for system diagnostics.
Application Scenarios
Specifically engineered for large-scale steam turbines in power generation facilities requiring high-voltage power supplies and strict safety voting logic.
Performance Parameters
- PFH (Probability of dangerous Failure per Hour): 7.8E-8 /h.
- MTTF (Mean Time to Failure): > 54,000 years.
Material Composition
Industrial-grade electronics housed in a robust enclosure designed for high-voltage isolation and harsh industrial environments.
Structural Characteristics
Backplane-mounted triple module system with dedicated high-voltage power terminals and voted relay output terminals.
Working Principle
Operates on the 2oo3 principle where at least two of the three modules must agree on an overspeed condition to initiate a trip, balancing safety and operational availability.
Installation Requirements
Ensure high-voltage power connections are strictly isolated and properly torqued. Follow all high-voltage safety protocols during installation.
Precautions for Use
Only qualified high-voltage personnel should handle the installation and maintenance of this specific HV/HV variant. Always verify the power supply matches the HV/HV rating before energizing.
