About the IS200VAOCH1A
The IS200VAOCH1A is an Analog Output board marketed by General Electric as part of their Mark VI IS200 series. The Mark VI Series that this IS200VAOCH1A Analog Output Board device belongs to has to be considered quite the stark functional upgrade upon the previous industry-standard Mark V Turbine Control System Series of essentially the exact same full extended product series title, as the Mark V Series' established gas and steam possible functional environments were expanded to include the alternative energy-focused wind turbine functional setting with the rollout of the Mark VI Series specifically. With this being the case, this IS200VAOCH1A Analog Output Board's greater Mark VI Turbine Control System Series is also separately held in high esteem on relevant promotional industrial markets given its nature as one of General Electric's final-developed Mark GE product series to make use of the patented Speedtronic control system technology first seen with the release of the Mark I Series way back in 1969.
Hardware Tips and Specifications
This board controls 16 analog 20mA outputs wired to analog terminal boards like the DTAO board or the TBAO board. The VAOC board accepts digital values through the VME backplane via the VCMI board, then converts them to analog output currents. The currents are sent to one of the terminal boards for measurement and then are returned to the VAOC for control. The user must note the IS200VAOCH1A is an earlier-generation board that supports a lower resistance. This board supports a load resistance of up to 500 Ω at the end of 1000 feet of #18 wire. According to the IS200VAOCH1A Analog Output Board original instructional manual materials made available for your viewing convenience to our manuals tab above, this IS200VAOCH1A Analog Output Board product comes with a General Electric-specified set of installation procedures and related hardware details. For starters, this IS200VAOCH1A Analog Output Board device offers sixteen total analog outputs, as mentioned above. Each one of these outputs is made available in one of two total terminal output blocks, with each of these terminal blocks being held down by two screws. Each one of these terminal blocks has twenty-four total terminals per each block, with the terminals accepting the number twelve style of AWG wires available. This IS200VAOCH1A Analog Output Board product is not the originally-developed PCB of its specific GE Mark VI Series functionality, as that would have to be considered the IS200VAOCH1 Parent Analog Output Board notably not utilizing this IS200VAOCH1A Analog Output Board device's sole A-rated functional product revision.
Attached to the front edge of the IS200VAOCH1A is a narrow single-slot faceplate. The faceplate has three components built into its surface: a green LED (RUN,) a red LED (FAIL,) and an orange LED (STATUS.) The board surface includes two backplane connectors along with connectors designed with conductive dots and traces. There are sixteen relays located on the board surface, along with dozens of integrated circuits. These circuits include FPGAs (field programmable gate arrays,) oscillating chips, and SRAM chips. The board has various resistors, diodes, and capacitors. One feature of the IS200VAOCH1A model is that it is equipped with noise suppression circuitry, the noise suppression circuitry is used to protect against high-frequency and surge noise mounted within the terminal board. The cables needed to wire them model have molded plugs that will connect the terminal board, such as the TBAO to the VME rack where the VAOC processor board is located.
