Technical Specifications Module Type: Multi‑channel vibration transducer signal processing board Applicable System: GE Mark VI Turbine Control System Input Signal Type: Vibration sensor analog 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 Receives and conditions multi‑channel bearing and shaft vibration sensor signals. Calculates vibration amplitude and related measurement parameters. Transmits vibration measurement data and alarm status to main controller via backplane bus. Front‑edge LED indicators reflect channel signal validity and board operating status. Built‑in self‑diagnosis detects sensor signal loss and board internal hardware faults. Supports vibration‑level alarm and protection‑logic triggering for turbine units.
Application Scenarios Turbine bearing and shaft vibration signal processing inside Mark VI control cabinet. Condition monitoring for power‑plant gas‑turbine and steam‑turbine rotating machinery. Spare‑part replacement for legacy Mark VI power‑plant control hardware.
Structural Characteristics Standard plug‑in PCB structure compatible with Mark VI rack slots. Front‑edge LED indicator array for vibration‑channel and board status display. Rear golden‑finger connector for backplane bus communication and power supply. On‑board vibration signal filtering, conditioning and measurement circuit. Locking assembly for anti‑vibration mechanical fixation inside rack.
Working Principle Vibration transducer analog signals enter board input channels. Signals pass through specialized filter and conditioning circuits. On‑board hardware computes vibration amplitude values. Measurement results and status flags are transmitted to main controller via backplane bus.
Installation Requirements Insert board into vibration‑monitor designated slot of GE Mark VI control rack. Carry out rack protective grounding complying with GE power‑plant grounding specification. Field vibration sensor cables must use dedicated shielded cables and keep away from high‑voltage power cables.
