About the IS200VVIBH1CAC
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 and Specifications
The IS200VVIBH1CAC functions as a Vibration Monitor board. This PCB processes vibration probe signals from the DVIB or TVIB terminal boards. These probes connect directly to the terminal board. Up to fourteen probes can connect to a board. This IS200VVIBH1CAC VME Monitor Board PCB is actually not the originally-developed product of its specific GE Mark product series functionality, as that would in fact have to be considered the IS200VVIBH1 parent VME Monitor Board notably not utilizing any one of this IS200VVIBH1CAC VME Monitor Board product's three total significant product revisions. As you probably have been able to guess based off of its basic GE-formulated product description, this IS200VVIBH1CAC VME Monitor Board device was developed with VME Rack installation specifically in mind, as is further proven by the existence of a metallic installation faceplate on the side of this IS200VVIBH1CAC VME Monitor Board product's base PCB. 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 terminal boards that connect to the IS200VVIBH1CAC support Seismic, Proximitor, Velomitor, and Accelerometer probes of the type furnished by Bently Nevada. In both Simplex or TMR mode power for these probes originate from the IS200VVIBH1CAC board. 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. Integrated circuits (over fifty,) include a Xilinx Spartan field-programmable gate array (FPGA,) as well as several types of RAM and SRAM chips. Technical support for this component was provided by GE. Please refer to the MKVI Control System Guide for more information, including alarms, fault codes, and a list of possible causes.
