About the IS200VVIBH1CAB

The IS200VVIBH1CAB is a board component manufactured by General Electric as part of their Mark VI system. Released in the 1990s, the Mark VI serves as a steam and gas turbine management system under the “Speedtronic” family. It utilizes TMR (Triple Modular Redundant) architecture, which includes three independent control modules, power supplies, and communication networks (IONets). A simpler Simplex configuration is also available for smaller systems requiring less complexity.

Hardware Overview and Specifications

The IS200VVIBH1CAB functions as a Vibration Monitor Board within the Mark VI system. It processes signals from vibration probes connected to DVIB or TVIB terminal boards. These probes measure rotor axial position or eccentricity, differential expansion, and vibration. Compatible probe types include:

• Seismic

• Phase

• Proximity

• Acceleration

• Velocity

Additionally, Bently Nevada vibration monitoring equipment can be permanently connected to the TVIB board.

Key Hardware Features

• Component Density: The board is densely populated, including over fifty integrated circuits such as Xilinx Spartan XCS30 Field Programmable Gate Arrays (FPGAs).

• Memory: Contains SRAM and RAM chips.

• Components: Capacitors, resistors, inductors, and six connectors (including two backplanes) are mounted on both front and back surfaces.

• Faceplate: Marked with the board number and equipped with three LED indicators.

Installation and Maintenance

Please strictly follow manufacturer guidelines and procedures for installing or maintaining the IS200VVIBH1CAB. Installation manuals and datasheets, including the system control guide (GEH-6421), provide detailed instructions.

Additional Notes

This IS200VVIBH1CAB VME Vibration Board, despite being widely used, has limited online documentation. The detailed information here is derived from expert technician visual inspections, making this functional product number a useful reference for hardware and component specifications.

The product number itself encodes important device information, such as:

• IS200 series tag: Identifies the product as part of the Mark VI series and its GE domestic manufacturing origin.

• VVIB acronym: Denotes its role as a Vibration Board.

• Mark VI series grouping: Part of group one in the Mark VI lineup.

• PCB coating: Conformal protective layer applied to the PCB.

• Revisions: Reflects the triple revision history (functional and artwork).
