The GE IS200VVIBH1CAB is a Vibration Monitor Board designed for the Mark VI turbine control system. This advanced component processes signals from up to 26 vibration probes to monitor turbine health and performance.

• Comprehensive Probe Support: Compatible with Bently Nevada probes including proximity, velocity, acceleration, seismic, and phase sensors
• High-Speed Data Processing: Samples at 4600 samples/second with precise peak-to-peak displacement/velocity calculations
• Flexible Operation Modes: Supports both simplex and Triple Modular Redundant (TMR) configurations
• Advanced Power Management: Supplies -28V DC to probes with regulation to -23 to -26V DC and short-circuit protection
• Configurable Signal Processing: Features wideband filters with adjustable poles and cutoff frequencies
• Comprehensive Diagnostics: Monitors hardware/software limits while ignoring DC components to prevent false trips
• Seamless Integration: Connects to VME racks via edge connectors with front-panel LEDs for troubleshooting
• Scalable Monitoring: Handles 26 probes via two TVIB boards for comprehensive rotor vibration, axial position, and eccentricity monitoring

Part of GE's Speedtronic technology, the IS200VVIBH1CAB digitizes vibration data and transmits it to the controller via the VME bus. In TMR mode, it utilizes a diode high-select circuit for redundancy, ensuring reliable turbine control in critical applications.
