Technical Specifications Module Type: Servo‑valve analog drive output board Applicable System: GE Mark VI Turbine Control System Output Signal Type: High‑precision analog servo drive signals 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 Generates high‑precision analog servo drive signals for turbine servo‑valve hardware. Receives digital valve‑position control commands from main controller via backplane bus. Interfaces with field servo‑valve actuators for fuel and steam valve closed‑loop control. Front‑edge LED indicators show board running status and signal‑channel condition. Built‑in hardware self‑diagnosis detects drive‑channel abnormality and reports fault flags.
Application Scenarios Servo‑valve drive output inside Mark VI gas‑turbine and steam‑turbine control cabinet. High‑precision valve position regulation for power‑plant turbine units. Spare‑part replacement for existing Mark VI power‑plant control installations.
Structural Characteristics Standard plug‑in PCB form factor matching Mark VI rack mechanical specification. Front‑edge LED status indicator group for board and channel status visualization. Rear golden‑finger connector for backplane bus communication and power supply. On‑board high‑precision analog servo drive and signal‑conditioning circuit. Locking hardware ensures vibration‑resistant fixation inside rack.
Working Principle Main controller transmits digital valve‑position command to board via backplane bus. On‑board circuit converts digital value into high‑precision analog servo drive signal to control field servo‑valve actuator. Servo‑loop related feedback signals are processed on‑board and relevant data is sent back to main controller. Diagnostic circuit continuously monitors drive‑channel integrity and hardware health.
Installation Requirements Insert board into designated servo‑output slot of GE Mark VI control rack. Complete rack protective grounding strictly following GE power‑plant grounding specification.
