IS200VTURH1BAC Functional Description 

The Primary Turbine Protection Board IS200VTURH1BAC General Electric serves as a critical Primary Turbine Protection Board within the Mark VI control system, specifically designed to monitor and manage turbine overspeed protection. This sophisticated board controls three primary overspeed trip relays located on terminal boards, with trip signals processed through either the VTUR or VPRO modules before activating emergency solenoids via TRPG. In TMR (Triple Modular Redundant) systems, all nine magnetic relays engage, while simplex configurations utilize only three, ensuring flexibility across different operational requirements.

Engineered for precision, the IS200VTURH1BAC General Electric Turbine Specific Primary Trip Board  supports MPU pulse rates ranging from 2 Hz to 20 kHz with an accuracy of 0.05%, crucial for real-time turbine speed monitoring. The board interfaces with TRPG, TRPL, TREG, and TRPS terminal boards, while its 20 V DC (HI) and 6 V DC (LO) contact voltage sensing ensures reliable fault detection. Additionally, Turbine Control IS200VTURH1BAC General Electric facilitates automatic generator synchronization and main breaker control, working in tandem with the TTUR module for permissive synchronization relays.

The GE IS200VTURH1BAC Primary Turbine Protection Card is compatible with both simplex and TMR architectures, adapting to varying redundancy needs. In simplex mode, it processes four pulse rate signals for turbine speed measurement, while also monitoring shaft voltages and currents via brush pickups. Its integration with the turbine controller and excitation system enables seamless voltage regulation, while high-voltage alarms and circuit integrity tests enhance system diagnostics, as documented in GEH-6421 (Mark VI System Guide).

Widely deployed in gas and steam turbine systems, the IS200VTURH1BAC Mark Vi Vme Turbine Control Board ensures fail-safe operation through redundant trip pathways and real-time monitoring. Its ability to trigger emergency solenoid activation via TRPG relays makes it indispensable in preventing catastrophic overspeed events. With its proven reliability in power generation automation, this board remains a cornerstone of GE’s Mark VI protection systems, balancing high-speed accuracy with robust safety protocols.
