About the IS200VCCCH1BBC
The IS200VCCCH1BBC model is marketed as a Discrete Input Output printed circuit board. This PCB exists as a member of the trusted manufacturer General Electrics' child company, GE Industrial Systems, as part of their Mark VI Speedtronic series of automated drive components. Unlike earlier legacy series in the GE Industrial Systems Mark IV or Mark V series, the Mark VI Speedtronic series is still being manufactured by General Electric today, and is not considered a legacy component product. The VCCC works in close proximity with the related VCMI component board; passing input voltages through optical isolators and transferring their signals over the VME backplane to this aforementioned VCMI part. The IS200VCCCH1BBC part, while revised with functional revisions rated at B and an artwork revision of C; still carries the functional acronym VCCC and may oftentimes be simplified to this moniker in industry circles. This IS200VCCCH1BBC Discrete I/O Board product's greater Mark VI Turbine Control System Series is generally very much valued on relevant promotional industrial markets, purely for the fact that it exists as one of General Electric's final-developed Mark product series to exhibit the patented Speedtronic control system technology across a range of differing product offerings.
Hardware Tips and Specifications
As a Discrete Input Output board or DIO for short, the VCCC board will control up to four contact relay outputs as well as termination boards depending on the rack that the model has been installed. In addition to these contact relay outputs, the VCCC accepts 48 discrete outputs and controls 24 relay outputs. This increased number of relays present on the base plate of the VCCC increase its total overall size, necessitating configuration as a double width module. 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. This assembly's VME backplane is where the VCCC takes signals passed through optical isolators to the VCMI, where they will be sent on to the controller. This process is supported through contact inputs featuring noise suppression circuitry designed to curb voltage surge or high frequency noise. 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. This daughterboard, although sometimes revised or replaced, can be defined as the TRLYH1B daughterboard, and houses twelve magnetic plug-in relays.
Another additional visual feature of the IS200 VCCC is the Discrete Input/Output Board's three LEDs on the front faceplate labeled run, status, and fail. The face plate's RUN led flashed green to indicate a normal drive assembly running condition. VCCC's FAIL led glows solid red when a functional failure of the VCCC within the greater drive assembly is detected. The final LED is usually a non-factor, but displays a steady orange color when a diagnostic alarm condition is discovered by the IS200VCCCH1BBC. 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 aforementioned TRLY PCB and the TICI component board. 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.
