The IS200VTURH1BAA is a VME-bus Turbine Specific Primary Trip Board designed for the Mark VI Speedtronic control system architecture. Functioning as a critical hardware-level protection asset, this board interfaces directly within the control rack to process primary turbine protection parameters, including shaft overspeed, acceleration, and emergency manual trips.
Relay Output Controls for Emergency Shutdown
Dual Flame Detector Signal Processing Channels
Direct Integration into VME Rack Enclosures
The board is equipped with specialized input channels to receive raw pulses from magnetic pickups (active or passive speed sensors). It continuously monitors turbine shaft rotation to compute exact speed values independent of the main controller processors. Additionally,it processes synchronous status inputs from generator circuit breakers, fluid pressure switches, and vibration monitoring interlocks.
The IS200VTURH1BAA executes embedded overspeed detection algorithms and hardware-level vote logic (such as two-out-of-three matrix configurations). Upon detecting any violation of pre-programmed trip limits or receiving external emergency shutdown commands, the board immediately de-energizes its onboard electro-mechanical trip relays, venting hydraulic fluid to shut off fuel or steam valves.

Thermal Power Generation
Monitors shaft speed of primary steam turbine generators in coal or gas-fired power plants, directly de-energizing emergency trip systems (ETS) to close main stop valves during sudden load rejection or overspeed.
Nuclear Power Industry
Provides safety-compliant primary trip protection for high/low-pressure main steam turbines and high-power reactor feedwater pump turbines in the conventional island of nuclear power plants.
Petrochemical & Refining
Used for emergency safety shutdown protection of driving turbines for large cracked gas compressors and rich gas compressors in million-ton ethylene plants or refineries.
Coal Chemical Industry
Monitors large air separation turbine compressor units and syngas compressor units in coal-to-liquids or coal-to-methanol plants to prevent turbine runaway overspeed.
Iron & Steel Metallurgy
Utilized for speed monitoring and two-out-of-three trip voting on blast furnace Top Gas Recovery Turbine (TRT) power generation units and blast furnace blower-driving turbines.
Seawater Desalination
Provides overspeed safety control for high-pressure steam driving turbines or large high-pressure pump shafts acting as primary power sources in large thermal or membrane desalination plants.
Completely isolate and power down the system before inserting, removing, or wiring the module within the VME rack; live operation is strictly prohibited to prevent electronic component damage. During commissioning and maintenance, configure the over-speed trip and flame monitoring channel parameters strictly according to the Mark VI control manuals, and ensure that field sensor cable shields are correctly grounded to suppress electrical noise interference.
Technical notes
The IS200VTURH1BAA features dedicated diagnostic LEDs on its front panel to indicate communication status (TX/RX), card health status (OK), and active trip conditions. Through the VME backplane, the board transmits real-time speed data, hardware self-test diagnostic codes, and trip sequence event logs to the central HMI for troubleshooting and chronological fault analysis.
