Product Description

The IS200VCMIH2B is a component created by GE for the Mark VI system.  The Mark VI is a gas/steam turbine management system released by General Electric as part of their “Speedtronic” line.  This line of turbine management systems began with the Mark I in the 1960s and continued on through the release of the Mark VI and Mark VIe, which occurred decades later.  The Mark VI is usually powered by a 125 Vdc battery system but can be powered by a 120/240 vac source using a power converter with a transformer to rectify this source to 125 Vdc.  The MKVI is designed for operation within an air-cooled equipment room.

The IS200VCMIH2B is mounted in slot one of the Central Control Module.  This PCB allows internal communications to occur within I/O cards located within the card rack and also within other Control Modules or Protection Modules.  

The IS200VCMIH2B has a front faceplate attached.  This faceplate has multiple components mounted into its surface.  This includes three DIN connectors that are labeled IONet1 through IONet3.  The faceplate has one reset switch and one 9-pin male serial connector. The board also has multiple LED indicators.  This includes a set of three LEDs at the top and bottom of the faceplate, a set of eight LEDs toward the middle, and another set of six LEDs below these.  

The IS200VCMIH2B includes two backplane connectors.  The board has two vertical pin connectors, including a ribbon connector. The board has several connectors made up of conductive traces.  The board has three transformers, several transistors, and over fifty integrated circuits, including two field programmable gate arrays. The board includes resistors, diodes, and capacitors.  These components are located on both surfaces of the board.
