Technical Specifications Module Type: Turbine governor regulator signal interface board Applicable System: GE Mark VI Turbine Control System Signal Type: Actuator command output and position feedback input Backplane Interface: Mark VI internal backplane bus Operating Power: Supplied via Mark VI rack backplane Operating Temperature: ‑30 ℃ to +70 ℃ Storage Temperature: ‑40 ℃ to +85 ℃ Relative Humidity: 5%‑95%, non‑condensing Mechanical Dimension: Standard Mark VI plug‑in PCB board Certifications: CE, UL power generation industrial component compliance
Functional Features Interfaces with turbine hydraulic fuel regulating actuator for closed‑loop governor control. Conditions control command signals sent to field hydraulic governor hardware. Receives and processes actuator position feedback signals from field side. Transmits command and feedback data between field actuator and main controller via backplane bus. Front‑edge LED indicators show board operating state and signal channel status.
Application Scenarios Fuel governor closed‑loop control signal interface inside Mark VI turbine control cabinet. Hydraulic actuator command and feedback processing for power‑plant gas‑turbine and steam‑turbine units.
Structural Characteristics Standard plug‑in PCB form factor matching Mark VI rack specification. Front‑edge LED status indicator group for board and channel condition display. Rear golden‑finger connector for backplane bus communication and power supply.
Working Principle Main controller sends fuel‑regulation command value to board via backplane bus. On‑board circuit converts digital command into suitable analog drive signal for field hydraulic actuator. Position feedback signal returned from actuator enters this board, undergoes conditioning and conversion, and feedback measurement value is sent back to main controller through backplane bus to close regulation loop.
Installation Requirements Insert board into designated governor‑interface slot of Mark VI control rack. Strictly implement rack protective grounding following GE power‑plant grounding specification. Field actuator signal cables adopt shielded twisted‑pair cables and separate routing from high‑voltage power cables.
