GE IS200VVIBH1A

Key Specifications

Advantages & Distinctive Features

• Comprehensive Vibration Monitoring: Supports all major sensor types (proximity probes, accelerometers, velocity sensors)—eliminates separate dedicated vibration monitors.

• High-Speed Simultaneous Sampling: Up to 20 kHz per channel ensures accurate capture of high-frequency vibration components—critical for early fault detection.

• Integrated Protection Logic: On-board alarm and trip level processing ensures deterministic trip response for over-vibration events.

• Programmable Signal Conditioning: Per-channel gain, offset, and filtering allow optimization for different sensor types and installation conditions.

• Non-Volatile Fault Logging: 500 events with timestamps enable post-event analysis and predictive maintenance.

• Built-in Self-Test: Continuous sensor health monitoring (bias voltage, open/short detection) prevents false trips.

• Shaft Position Monitoring: Thrust bearing wear detection and axial position monitoring.

• I/O Net Integration: Seamless communication with processor boards via redundant Ethernet links.

• Hot-Swappable: Supports removal and replacement without powering down the rack.

• Direct Retrofit: Replaces older VVIB series boards.

Application Fields

• Gas Turbines: Bearing vibration, shaft displacement monitoring

• Steam Turbines: Bearing and casing vibration, thrust position monitoring

• Compressors: Centrifugal and axial compressor vibration for surge protection

• Generators: Stator end-winding and bearing vibration

• Pumps: Critical feedwater and boiler circulation pump vibration

• Fans and Blowers: ID/FD fan bearing vibration

• Wind Turbines: Main bearing and gearbox vibration

Comparison with Competitors

The GE IS200VVIBH1A offers superior channel density, sensor compatibility, sample rate, and integrated protection compared to competitors—making it the ideal solution for comprehensive machinery protection in a single VME slot.

Selection Guidelines

• When to choose: Any Mark VIe application requiring vibration monitoring and protection—gas turbines, steam turbines, compressors, generators, or critical pumps.

• Sensor Selection: Verify field sensors are compatible. Proximity probes require ±24 VDC power supply; accelerometers may need IEPE excitation (2–10 mA, programmable).

• Filtering Configuration: Program low-pass filters per channel to reject high-frequency noise while preserving relevant vibration frequencies.

• Alarm/Trip Level Setting: Configure alert and danger levels per API 670 guidelines—start with 50% of sensor range for alert, 80% for danger.

• Compatibility: Fits all Mark VIe VME64x racks. Requires processor board (VPRO series) with I/O Net connectivity and ControlST v6.0 or higher.

Operational Precautions

1. Wiring: Follow GE wiring diagrams (GEH-6860)—correct polarity and shield grounding essential. Use shielded twisted-pair cables; ground shield at terminal board only.

2. Sensor Bias Voltage Check: For proximity probes, verify bias voltage within specified range (–24 V to –4 V) via Toolbox ST—out-of-range indicates sensor or cable fault.

3. Calibration: Factory calibrated—verify vibration amplitude against known reference during commissioning for critical protection channels.

4. Alarm/Trip Testing: Perform simulated vibration tests (function generator or manual barring) to verify alarm and trip logic.

5. LED Diagnostics: Green = normal; Amber = alert; Red = danger/trip. Review fault logs for detailed event analysis.

6. Fault Log: Access 500-event log via Toolbox ST for post-event analysis.

7. Hot-Swap: Remove/insert slowly under power—processor auto-recognizes new module.

8. Spare Stock: Maintain at least one spare GE IS200VVIBH1A per 3–4 active racks.

9. Annual Verification: Verify each channel against known vibration reference during outages; compare baseline data.

10. Filter Setting Review: Review filter settings annually—adjust if new vibration frequencies appear.

11. Firmware Updates: Ensure the GE IS200VVIBH1A is in “standby” mode during updates.

12. ESD: Handle by edges only with grounded wrist strap.
