Technical Specifications Module Type: Multi‑channel analog input conditioning board Applicable System: GE Mark VI Turbine Control System Input Signal Type: Industry standard analog transducer 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 analog input reception for field process transducer signals. On‑board signal filtering and galvanic isolation improves noise immunity. Analog‑to‑digital conversion for field analog variables. Transmits digitalized process data to main controller over backplane bus. Front‑edge LED indicators display channel and board running status. Built‑in self‑diagnosis detects open‑circuit, over‑range and hardware faults.
Application Scenarios Field analog process signal acquisition inside Mark VI turbine control cabinet. Pressure, flow and temperature signal measurement for power‑plant turbine units. Spare‑part replacement for existing Mark VI power‑plant control installations.
Structural Characteristics Standard plug‑in PCB structure matching Mark VI rack mechanical specification. Front‑edge LED status indicator array for channel status indication. Rear golden‑finger connector for backplane data communication and power supply. On‑board isolation, filtering and analog‑to‑digital conversion circuitry. Locking hardware for vibration‑resistant fixation inside rack.
Working Principle Field analog transducer signals feed into board input channels. Signals pass through filter and isolation circuits before analog‑to‑digital conversion. Digital measurement values are sent to main controller via backplane bus.
Installation Requirements Insert board into target slot of GE Mark VI standard control rack. Carry out rack protective grounding strictly following GE power‑plant grounding specification. Field analog wiring employs shielded cables and keeps separation distance from high‑voltage cables. Confirm transducer signal type matches channel configuration before power‑on. Cabinet ambient temperature and humidity must stay within rated range without condensation.
