GE IS200VVIBH1A PCB board
GE IS200VVIBH1A
1. Overview
The GE IS200VVIBH1A is a printed circuit board (PCB) manufactured by General Electric (GE) for its Mark VI system, belonging to the Speedtronic series of gas and steam turbine management systems. As a VME Vibration Card, it is primarily designed to monitor and process vibration signals generated by rotating machinery.
2. Structure and Composition
Core Functional Unit: Equipped with a vibration signal processing circuit, which is responsible for processing vibration probe signals transmitted from DVIB/TVIB terminal boards.
On-board Components: Integrated with a full range of electronic components including inductors, capacitors, resistors, and integrated circuits such as SRAM, RAM, and Xilinx Spartan FPGA.
Indicator Lights: Three LED indicators are mounted on the board, separately indicating Run status, Fault status, and System Status.
Connection Mode: Vibration probes are directly connected to DVIB or TVIB terminal boards, with power supplied by the IS200VVIBH1A PCB. The collected vibration signals are digitized on the VVIB board and then transmitted to the controller via the VME bus.

Note: Newer derivative models of IS200VVIBH1A (such as IS200VVIBH1C) have officially published specifications including dimensions (233mm×165mm×45mm), weight (approximately 1.2kg), and environmental parameters (humidity: 5%～95% non-condensing, vibration: 5g RMS, etc.). However, there is no official unified parameter table publicly released for the standard IS200VVIBH1A model. All above parameters are sourced from verified public search results.
4. Product Features
Professional Vibration Monitoring: It monitors shaft vibration, proximity and proximity reference of turbines and other rotating machinery, effectively identifying early wear and tear to prevent costly unplanned downtime.
High-Reliability Design: Featuring a robust and durable board structure, it can adapt to harsh and complex industrial operating environments with strong environmental tolerance.
Multi-Probe Compatibility: Supports mainstream vibration sensor types including proximity sensors, velocity meters, seismometers and accelerometers, with wide application adaptability.
Full Digital Processing: All analog probe signals are digitized on-board and stably transmitted to the controller through the VME bus, ensuring high signal accuracy and anti-interference performance.
Flexible Configuration: The vibration input channels can be flexibly configured as 4 or 8 channels according to actual industrial monitoring requirements.
5. Application Fields
The IS200VVIBH1A vibration monitoring card is widely applied in industrial rotating equipment monitoring scenarios, mainly including:
- Core vibration monitoring for gas turbines and steam turbines in Mark VI control systems
- Vibration level monitoring for auxiliary rotating machinery such as compressors, fans and pumps
- Condition monitoring and fault diagnosis of large-scale rotating equipment in power plants, petrochemical and other heavy industrial fields
6. Installation and Maintenance
Installation Method: As a standard VME bus board, it is installed on the VME backplane of the Mark VI system, and realizes data interaction with processor cards, I/O modules and other system components via the VME bus.
Probe Wiring Specification: Vibration probes are directly wired to DVIB/TVIB terminal boards, and the entire probe system is powered by the IS200VVIBH1A PCB board.
Diagnosis and Maintenance: The Mark VI system is equipped with built-in hardware and software diagnostic functions. The three on-board LED indicators (Run/Fault/Status) support real-time and quick judgment of the board’s operating status, facilitating daily inspection and fault troubleshooting.
