Technical Specifications Module Type: Discrete binary output drive board Applicable System: GE Mark VI Turbine Control System Output Signal Type: Conditioned discrete on‑off 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 Multi‑channel discrete binary output to drive field relays and solenoid actuators. Electrical isolation between control internal circuit and field load side. Receives control commands from main controller through backplane bus. Front‑edge LED indicators display real‑time output channel on‑off status. Built‑in hardware self‑diagnosis monitors board circuit health and reports faults. Supports turbine auxiliary equipment control and safety interlock output actions.
Application Scenarios Auxiliary actuator driving for gas‑turbine and steam‑turbine control system. Interlock and protection logic output inside Mark VI turbine control cabinet. Spare‑part replacement for legacy Mark VI power‑plant control installations.
Structural Characteristics Standard plug‑in PCB structure compatible with Mark VI rack mechanical requirements. Front‑edge LED array for output channel status indication. Rear golden‑finger connector for backplane bus communication and power supply.
Working Principle Main controller sends discrete control commands to this board via backplane bus. Internal drive circuit activates corresponding output channel according to command. Isolation barrier separates field load circuit from control system internal circuit.
Installation Requirements Install board into appropriate slot of GE Mark VI standard control rack. Complete rack protective grounding complying with GE power‑plant grounding specification. Field load wiring must match channel rated voltage and current parameters.
