Technical Specifications Module Type: VME‑based vibration transducer signal processing board Applicable System: GE Mark VIe Turbine Control System Input Signal Type: Vibration sensor analog signals Bus Interface: Mark VIe VME backplane bus Operating Power: Supplied via Mark VIe VME rack backplane Operating Temperature: ‑30 ℃ to +70 ℃ Storage Temperature: ‑40 ℃ to +85 ℃ Relative Humidity: 5%‑95%, non‑condensing Mechanical Dimension: Standard Mark VIe VME form‑factor plug‑in PCB board Certifications: CE, UL power generation industrial component compliance
Functional Features Multi‑channel vibration sensor signal reception and conditioning for Mark VIe VME control system. Calculates vibration amplitude and related measurement parameters of turbine rotating components. Transmits vibration measurement data and fault‑alarm status to main controller via VME backplane bus. Front‑edge LED indicators reflect signal‑channel validity and board operating status. Built‑in self‑diagnosis detects sensor signal loss and board internal hardware faults. Supports vibration‑related alarm and protection‑logic triggering for Mark VIe turbine equipment.
Application Scenarios Turbine bearing and shaft vibration signal processing inside Mark VIe control cabinet. Condition monitoring for power‑plant gas‑turbine and steam‑turbine rotating machinery. Spare‑part replacement for existing Mark VIe power‑plant control installations.
Structural Characteristics Standard VME‑form‑factor plug‑in PCB matching Mark VIe rack mechanical requirements. Front‑edge LED status indicator array for vibration‑channel and board condition display. Rear VME golden‑finger connector for VME bus communication and power supply access.
Working Principle Field vibration transducer analog signals are fed into board input channels. Signals pass through filter and conditioning circuits for noise suppression. On‑board hardware completes vibration‑value calculation. Measurement results and status flags are sent to main controller via VME backplane bus.
Installation Requirements Insert board into vibration‑monitor assigned VME slot of GE Mark VIe control rack. Complete rack protective grounding complying with GE power‑plant grounding specification. Field vibration sensor cables use dedicated shielded cables and separate routing from high‑voltage power cables.
