GE IS200VVIBH1CAC Vibration Monitor Board

Technical Specifications 

The IS200VVIBH1CAC is a GE printed circuit board manufactured for the Mark VI system.  The Mark VI was one of several management systems for gas and steam turbines released by GE under the “Speedtronic” name. The fact that this IS200VVIBH1CAC VME Monitor Board product's Mark VI Turbine Control System Series exists as one of the final-developed GE Speedtronic series greatly increases its overall market desirability. This IS200VVIBH1CAC VME Monitor Board printed circuit board product offering's Mark VI Series, as you can probably tell based off of its full extended product series title by itself, exists with a specific set of possible functional applications in gas, steam, and wind turbine-based product environments; this is a notable step up from the Mark V Series of previous industry-standard status as the Mark V Series' intended gas and steam turbine-based functional application range was expanded by the addition of the Mark VI Series' added wind turbine functional application.

Hardware Tips 

This IS200VVIBH1CAC VME Monitor Board device's base printed circuit board is afforded at least some protection through its conformal style of thin chemically-applied PCB protective coating. The IS200VVIBH1CAC digitizes these signals and sends them to the controller via the VME bus. Vibration probes are used for four protection functions, including: 
Vibration
Rotor Eccentricity
Differential Expansion
Rotor Axial Position
The IS200VVIBH1CAC includes a faceplate with three LED indicators. These are labeled as fail, status, and run. The faceplate connects to the surface of the PCB using three screws. The board has two backplane connectors that are labeled P1 and P2. The board has an additional four connectors. The board has several lines of inductor coils/beads located directly behind and parallel to the P2 backplane,  labeled L1 through L55. The board also carries various diodes, capacitors, and resistors. Components are located on both board surfaces. 

Installation

FAQ  技术常见问题解答

Q:What is the power source for the probes?
A；The probes are powered by -24 V dc obtained from the -28 V dc bus. Each probe supply is current-limited to ensure proper operation and prevent overload. The load per transducer is limited to 12 mA.

Q:How is the probe signal sampled?
A;The Vibration Monitor Board (VVIB) utilizes a 16-bit analog-to-digital converter (A/D converter) with 14-bit resolution for precise signal sampling. In fast scan mode (applicable for RPM ranging from 4,000 to 17,500), the sampling rate is 4,600 samples per second. For RPM less than 4,000, the sampling rate is 2,586 samples per second if nine or more probes are used. All inputs are simultaneously sampled within time windows of 160 ms, ensuring accurate data acquisition.

Q:What are the RPM limitations for utilizing vibration channels?
A:If the rated RPM exceeds 4,000 rpm, up to eight vibration channels can be used, while the remaining channels may be allocated for proximity or position measurements. However, if the rated RPM is less than 4,000, the system supports the use of all 16 vibration channels in addition to other probe functionalities.

Q:How accurate are the buffered outputs?
A:The buffered outputs maintain a high level of accuracy, with an amplitude accuracy of 0.1 percent when transmitting signals to the Bently Nevada 3500 vibration analysis system. This ensures precise and reliable vibration data for comprehensive system monitoring and analysis.
