IS200VVIBH1B

Product Description

The IS200VVIBH1B is a GE Mark VI board component, designed to fit into a GE Mark VI system.  The Mark VI is one of several gas and steam turbine management systems created and released by General Electric under the “Speedtronic” name.  The Mark VI, being the second-to-last of these systems, is also one of the most technologically advanced, and includes such features as Ethernet communication capabilities, a PC-based HMI (human-machine interface) and onboard diagnostics built into both the software and into the hardware.  HMIs and controls have optional time synchronization available using Global Positioning Satellite receivers.

The IS200VVIBH1B is a Vibration Monitor card designed to process vibration probe signals from TVIB/DVIB terminal boards.  Up to fourteen of these probes connect directly to the terminal boards and are powered by the IS200VVIBH1B. These probes are used for protection functions such as differential expansion, vibration, rotor eccentricity, and rotor axial position.  More information on how probes are set up and their use may be found in GE publication GEH-6421 (Mark VI Turbine Control System Guide.)

The IS200VVIBH1B is a single PCB component attached to a faceplate.  The faceplate attaches via three screw connections and is populated with three LED indicators.  The LEDs are labeled “run,” “fail,” and “status.” There are no other components mounted into the faceplate.

The board surface of the IS200VVIBH1B is populated by inductor coils (beads) marked L1 through L55.  The board has resistors and capacitors that appear on the front and rear surface of the board. Integrated circuits include field programmable gate arrays (Xilinx Spartan Xcs30,) and various types of RAM and SRAM chips.
