Description
GE IS200TRPGH1B
Technical Specifications: Features high-capacity, force-guided safety relays with redundant contact configurations. Monitored by the system’s diagnostic circuits for contact welding, coil failures, and mechanical binding. Rated for high inrush currents typical of solenoid valves.
Functional Features: De-energizes to trip (fail-safe design). Opens fuel valves, closes stop valves, and trips generator breakers when the turbine protection logic detects unsafe conditions. Contacts are continuously monitored for integrity.
Application Scenarios: Installed in the core safety loop of all GE Mark VI turbine control systems to protect personnel and equipment from catastrophic failure. Required by international safety standards for turbine protection.
Performance Parameters: Extremely fast response time (< 10ms) and high mechanical/electrical endurance. Contacts are rated for high inrush currents and feature positive-guided technology to ensure simultaneous opening of all normally-open contacts.
Material Composition & Structural Characteristics: Utilizes positive-guided relay technology to ensure normally-open and normally-closed contacts never close simultaneously. Housed in a robust, vibration-resistant package with conformal coating.
Installation Requirements: Wiring must adhere to strict safety standards. Redundant trip paths should be physically separated to prevent common-mode failures. Use dedicated wiring for trip circuits, separate from control wiring.
Usage Precautions: This board is part of a safety-rated system. Never bypass, modify, or test this board outside of approved maintenance procedures. Any suspected failure requires immediate system evaluation and potential turbine shutdown. Only qualified personnel should service this board.
