Key Features

1. Multi-Channel Precision Monitoring: Simultaneously processes 14 vibration/position inputs for comprehensive machinery health coverage.
2. High-Speed Signal Digitization: 16-bit ADCs and 4,600 SPS sampling deliver accurate, real-time data for vibration analysis.
3. Wide Sensor Compatibility: Supports proximity, acceleration, velocity, and displacement sensors for diverse monitoring needs.
4. Integrated Signal Conditioning: Onboard amplification, filtering, and noise reduction ensure clean data in harsh electrical environments.
5. TMR Redundancy Ready: Designed for simplex, dual, or triple-redundant Mark VI systems to eliminate single points of failure.
6. Real-Time Diagnostics & Alarming: Continuously monitors board and sensor health; triggers alerts for fault conditions (e.g., probe failure, signal overload).
7. VME Bus Mastering: Efficiently transmits digitized data to the Mark VI controller via the VME backplane for system-wide analysis.
8. Compact & Rugged Build: 6U VME form factor, conformal coating, and industrial-grade components ensure reliability in high-vibration, dusty, or humid environments.
9. Seamless Mark VI Integration: Plugs directly into Mark VI VME racks; compatible with native diagnostics and HMI tools for centralized monitoring.
10. Predictive Maintenance Enablement: Provides data for trend analysis, spectrum analysis, and fault pattern recognition (e.g., imbalance, misalignment, bearing wear).
