About the IS200VSVAH1ADD
This card connects to two terminal boards (TSVAs.) These boards control up to four electro-hydraulic servo valves that start the steam/fuel valves. They provide TMR (triple modular redundancy) control for retrofit applications if three-coil servo valves are not present. The IS200VSVAH1ADD has a faceplate with components mounted into it, including three LED indicators. The LEDs are green, red, and yellow. The faceplate has three cable connectors that are labeled “J5,” “J7,” and “J8.” The IS200VSVAH1ADD is built with four relays. It has too:
- two backplanes (P1 and P2)
- multiple integrated circuits
- field-programmable gate arrays
- digital signal processors.
- transistors, TP test points, diodes, resistors, and capacitors
- an internal sample rate of 200Hz
- a pulse rate accuracy of 0.05%
- 16-bit resolution at a 50 Hz frame rate
- multiple ferrite beads to minimize high-frequency noise
IS200VSVAH1ADD Number Researched
While some Mark VI models have abundant documentation on how they will function in the Mark VI system and alongside other models, such as the TSVA terminal boards in the IS200VSVAH1ADD models case, information for the VSVA models is difficult to find. It would be best to contact General Electric directly to see if they have information on this model, which would now be considered outdated. This IS200VSVAH1ADD PCB's IS200VSVAH1ADD functional product number starts off with a standard inclusion of th dually-functional IS200 series tag explaining this IS200VSVAH1ADD device's normal Mark VI Series assembly as well as its domestic original location of GE manufacture. This is not the only IS200VSVAH1ADD Board hardware trait exposed through this medium, with others existing such as the:
- Conformal PCB coating style
- Group one Mark VI Series grouping
- Three-fold revision table (full table)
