GE IS200TREGH1BEC Emergency Trip Terminal Board for Mark VIe Turbine

The GE IS200TREGH1BEC is an Emergency Trip Terminal Board, a critical safety component in GE's Mark VIe gas turbine control system. This board manages emergency trip solenoids to ensure rapid safety responses during critical scenarios like overspeed or emergencies.

• Emergency Trip Control: Manages three trip solenoids for rapid shutdown of fuel/steam valves through coordinated power distribution with the TRPG board.
• Redundant Relay Logic: Nine relays in three voting groups ensure reliable solenoid control, with the I/O controller managing overspeed protection and emergency stops.
• Power Management: Supplies 125V DC to solenoids with current suppression via MOV and uses 28V DC from the controller for relay coils.
• Diagnostic Monitoring: Tracks 125V DC feeder integrity, fuse conditions, and connections to proactively identify issues.
• Economizing Relays: KE1-3 relays reduce post-energization current load while maintaining solenoid readiness.
• Mark VIe Integration: Seamlessly integrates into the series' safety architecture with redundant, controlled emergency responses.
