Q-Bus Backplane Bus
Exclusive parallel internal bus adapted to Mark V triple-redundant R/S/T rack, responsible for real-time data exchange between the board and master CPU for protection signal uploading and command transmission.
Point-to-point Parallel Hardware Bus
High-speed hardwire connection with internal flame detection and interlock boards through edge connectors.
RS232 Serial Protocol
Onboard debugging port only for local offline calibration, PROM writing and equipment troubleshooting, unavailable for long-distance field transmission.

Gas Turbine Sets in Thermal Power Plants
Mounted inside Mark V triple-redundant cabinets of GE Frame 7 heavy-duty gas turbine generators. It acquires pulse signals from magnetic speed sensors to track rotor speed during startup, load regulation and load shedding. It activates fuel cutoff and emergency shutdown within 8ms upon overspeed to guard against rotor and blade damage, extensively used in large domestic combined-cycle power plants.
Steam Turbine ETS Protection in Conventional Power Plants
It monitors rotational speed independently from the main CPU, and links with flame detection and shaft vibration signals for interlock protection. It swiftly shuts steam intake valves during grid disconnection to prevent turbine runaway and stabilize grid operation.
Drive Turbines for Petrochemical Compressors
Deployed on turbines driving large gas compressors in refineries and gas pipeline stations. It delivers overspeed and flame-out interlock protection; isolated hardwired trip circuits avert communication faults and reduce risks of gas leakage and explosion.
Turbine Control on Offshore Oil & Gas Platforms
Applicable to offshore turbine power units. Its temperature tolerance and vibration resistance fit humid, salt-laden cabinet surroundings, providing real-time speed monitoring and emergency protection to sustain steady power supply for offshore production devices.
Steam Turbines for Waste Incineration Power Plants
It collaborates with temperature and pressure interlock signals to execute overspeed protection under abnormal boiler exhaust status, safeguarding generating equipment and maintaining steady operation of environmental facilities.
Equipment Overhaul and System Renovation
It acts as universal replacement spare parts for outdated Mark V control systems in aging power and chemical plants. Board replacement and safety upgrade with this module effectively lift the safety redundancy of old turbine control systems.
