General Electric IS42yPVIBH1B Unsafe vibration monitoring
The IS420PVIBH1B is a GE Mark VIe series PVIB type non-safety vibration monitoring I/O module, adapted for vibration/key phase/speed signal acquisition in turbines and rotating machinery. It features 4-channel vibration + key phase processing, a 24-bit ADC, and redundant IONet communication, making it a core component of Mark VIe rotating machinery condition monitoring.
Core Performance:
Signal Acquisition Capabilities
Channel Configuration: 4 vibration inputs (ICP/IEPE accelerometer) + 1 key phase/speed input, with electrical isolation between channels; a single channel failure does not affect other channels.
Signal Processing: 24-bit ADC, sampling rate up to 128kHz, supports FFT spectrum/time domain analysis, adapted for turbine shaft vibration, bearing vibration, and speed monitoring.
Diagnostics: Channel-level signal integrity monitoring, LED indicators for module/channel status, ControlST remote diagnostics, and rapid fault location.
Power Supply and Communication Characteristics
Power Supply: 24-28VDC redundant input, hot-swappable design, maintenance without interrupting system operation.
Communication: Dual 100M full-duplex Ethernet (IONet redundancy), compatible with Mark VIe TMR/DCS, seamless switching in case of link failure.
Expansion: Supports terminal block expansion, suitable for large-scale vibration signal acquisition scenarios.
Safety and Environmental Characteristics
Certifications: Class 1 Div 2/ATEX explosion-proof, suitable for deployment in hazardous areas.
Environment: Operating temperature -30℃ to 65℃, vibration/shock resistant, adaptable to harsh industrial environments.
Protection: Overvoltage/reverse connection protection, fault isolation, preventing system failure propagation.
