GE IS200VTURH1BAA Mark VI Primary Trip Board

The GE IS200VTURH1BAA is a turbine-specific primary trip board in the Mark VI Speedtronic system, critical for gas, steam, and wind turbine safety and control.

• Oversees turbine speed measurement with primary overspeed protection
• Manages automatic generator synchronization
• Controls main breaker operation
• Monitors shaft voltage and current
• In gas turbines, manages 8 Geiger Mueller flame detectors linked to TRPG

• Safety & Protection: Measures speed for overspeed trips, controls 3 trip relays, and monitors flame detectors/shaft parameters to prevent hazards
• Synchronization: Enables auto/manual generator synchronization with voltage and speed checks, using relays for safe breaker closure
• Redundancy Support: Works in TMR and simplex setups, ensuring reliability via redundant trip mechanisms
• Versatile Monitoring: Integrates voltage sensors and flame detectors for gas turbine-specific safety
• Easy Installation: Mounts in VME racks with lever-seated connectors and captive screws; front-panel LEDs aid diagnostics

Compatible with simplex and TMR systems, it controls 3 primary overspeed trip relays on TRPG, triggering emergency solenoids. It integrates generator/bus voltage sensors with 1,500V isolation, supporting 1,000ft wiring. Synchronization modes ensure safe breaker operation, with relays K25/K25A/K25P coordinating checks.
