Product Description
The IS200VCCCH1BBC model is marketed as a Discrete Input Output printed circuit board. As a Discrete Input Output board or DIO for short, it will control up to four contact relay outputs as well as termination boards depending on the rack that the model has been installed, the typical installation area for the VCCC board is a VME Rack. The chosen VME rack for this device will have twenty-one or thirteen slots. The inputs and outputs are used with this DIO board vary, the typical digital inputs used for this board are in the range of forty-eight while the digital outputs are in the range of twenty-four. The DIOs must be divided between two termination boards.
There are a variety of components that make up the IS200VCCCH1BBC board which include but are not limited to capacitors, resistors, DC power supplies, and test points. On the back edge of the board, there are different connector types, these connector types are vertical pin connectors and backplane connectors. If you are holding the VCCC board with the faceplate facing you, you will notice that there is a daughterboard located in the upper right-hand corner.
Integrated chips also make up a main portion of the IS200VCCCH1BBC board. There are sixty of these chips which are labeled SRAM, FGPA, and CMOS static RAM, just to name a few. There are also two plugs that are used to cable two other terminal boards in the Mark VI System. The two boards that are cabled to the VCCC model are the TRLY and TBCI boards. Please note that the two boards cabled to the VCCC model are referred to as barrier-type termination boards in the GER-4193A Speedtronic Mark VI Turbine Control System Manual.
