GE IS200TPROH1BCB | TPRO Turbine Protection Relay Output Board |

Core Functionality
Special relay terminal board for unit safety tripping, connected to VPRO protection processor card, outputs safety circuit signals such as emergency stop, fuel trip, overspeed protection, etc., drives the trip solenoid valve, and cuts off the actuator.
8 independent Form-C (SPDT) single pole double throw relay output channels; Each circuit is equipped with relay contact read back diagnosis to detect coil fault, contact adhesion and circuit break. TMR the third mock examination redundant architecture supports fault channel isolation to avoid false tripping and rejection risks.
Onboard MOV surge suppression, EMI filtering, PCB triple protection coating, suitable for strong electromagnetic and vibration cabinet environments in power plants.
Front end spring clamping terminal block for on-site cable connection; Interboard IDC cables are interconnected with VPRO processor cards.
Hot swapping is not supported, maintenance and replacement must be performed with power off; Static sensitive devices require anti-static grounding during disassembly and assembly.
