GE IS200TTURH1CFD Turbine Terminal Board in stock

GE IS200TTURH1CFD is a conformal coated turbine primary trip terminal board for GE Speedtronic Mark VIe turbine control system. It serves as the main relay termination interface between PTUR I/O processor pack and field protection devices, collecting overspeed, flame detection and emergency stop discrete signals, and executing voted primary trip commands through onboard safety relays.

This board adopts TMR triple modular redundant compatible design, equipped with barrier terminal blocks and surge suppression circuit. The conformal coating protects PCB against moisture and corrosive gas, widely used for gas turbine and steam turbine main fuel trip, generator breaker protection loops, and is a critical spare part for power plant Mark VIe protection cabinets.
