GE IS200VVIBH1CAB Vibration Monitor Board Mark VI

GE IS200VVIBH1CAB Vibration Monitor Board

Product Details:

The GE IS200VVIBH1CAB is a Vibration Monitor Board in the Mark VI turbine control system, processing signals from up to 26 vibration probes to monitor turbine health. Compatible with Bently Nevada probes (proximity, velocity, acceleration, seismic, phase), it digitizes vibration data and transmits it to the controller via the VME bus.

Operating in simplex or TMR modes, it supplies -28V DC to probes regulated to -23 to -26V DC with short-circuit protection and uses a diode high-select circuit in TMR for redundancy. It samples signals at up to 4600 samples/second, calculating peak-to-peak values for displacement/velocity in engineering units. Part of GE’s Speedtronic technology, it integrates with Mark VI’s TMR architecture for reliable turbine control.

Key Features:
Probe Compatibility: Supports diverse vibration probes and Keyphasor inputs for 1X/2X frequency analysis.

High-Speed Processing: Samples at 4600 samples/second, filtering data to derive peak-to-peak displacement/velocity metrics.

Redundancy Support: TMR configuration with -28V DC bus selection ensures fault tolerance; simplex mode offers streamlined operation.

Configurable Filtering: Wideband filters with adjustable poles and cutoff frequencies for signal conditioning.

Diagnostics: Monitors hardware/software limits, triggering alerts/trips for probe faults while ignoring DC components to avoid false trips.

Integration: Connects to VME racks via edge connectors; front-panel LEDs aid troubleshooting.

Scalability: Handles 26 probes via two TVIB boards, supporting rotor vibration, axial position, and eccentricity monitoring.
