Technical Specifications Module Type: Auxiliary signal conditioning I/O board Applicable System: GE Mark VI Turbine Control System Signal Type: Auxiliary discrete and analog auxiliary interface signals Backplane Interface: Mark VI internal backplane bus Operating Power: Powered by 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 Conditions multiple auxiliary field input and output signals for turbine auxiliary devices. Realizes level conversion and signal isolation between field side and control backplane. Routes auxiliary status feedback and control commands between field devices and main controller. On‑board diagnostic circuit monitors signal channel status and hardware health. Front‑edge LED indicators show channel operating and fault status. Supports system‑wide auxiliary interlock logic signal transmission.
Application Scenarios Auxiliary equipment signal interface inside Mark VI turbine control cabinet. Signal collection and command output for turbine auxiliary systems. Retrofit and spare‑part replacement for existing power‑plant Mark VI installations.
Structural Characteristics Standard plug‑in PCB structure for Mark VI rack slot installation. Front‑mounted LED status indicator array. Rear golden‑finger connector for backplane bus communication and power supply. On‑board signal conditioning, isolation and protection components.
Working Principle Field auxiliary signals arrive at board external terminals. On‑board circuits conduct filtering, isolation and level adjustment. Processed signals are transferred to main controller via backplane bus. Control commands from main controller pass through backplane to this board, converted to suitable signal levels for field auxiliary equipment driving. Built‑in diagnostics continuously monitor channel integrity.
Installation Requirements Insert board into specified slot of Mark VI standard control rack. Implement full protective grounding according to GE power‑plant grounding specification. Field signal cables use shielded cables and keep distance from high‑voltage power cables.
