Key Features

1. Multi-Probe Vibration Signal Processing
   • Simultaneously processes signals from up to 14 vibration probes, supporting four core mechanical protection functions: Vibration, Rotor Eccentricity, Differential Expansion, and Rotor Axial Position.
   • Compatible with Bently Nevada’s Seismic, Proximitor, Velomitor, and Accelerometer probes, ensuring seamless integration with industry-standard sensing equipment.
2. High-Precision Signal Digitization & Transmission
   • Converts analog vibration signals into high-resolution digital data for accurate analysis by the Mark VI controller.
   • Transmits digital data to the main controller via the VME bus with high-speed and high-reliability communication, avoiding data loss or distortion.
3. Simplex & TMR Redundancy Support
   • Operates in both Simplex (single-channel) and TMR (Triple Modular Redundant) modes, adapting to different system reliability requirements.
   • Supplies power to connected probes in both modes, simplifying system wiring and reducing external power supply dependencies.
4. Robust Industrial Design & Diagnostics
   • Compact VME form factor for easy installation in standard industrial control cabinets.
   • Wide operating temperature range and ruggedized components ensure stable performance in harsh power plant environments.
   • On-board LED indicators (Fail, Status, Run) enable real-time monitoring of board status and fault conditions, facilitating quick on-site troubleshooting.
5. Critical Mechanical Protection
   • Provides early warning and protection against abnormal mechanical conditions, preventing catastrophic failures and unplanned downtime of turbines and rotating machinery.
   • Enables condition-based maintenance by continuously monitoring mechanical health, optimizing maintenance schedules and reducing operational costs.

Application Scenarios
