About the IS200VSVOH1BED
The IS200VSVOH1BED is a PCB component made by General Electric for their Mark VI system. The Mark VI was one of GE’s last gas/steam turbine management systems released as part of their long-running “Speedtronic” line, which began in the 1960s when the first Mark I system was sold. The Mark VI is a technologically advanced turbine management system that includes Ethernet communications capabilities. It has integrated software and hardware and includes an operator interface (also known as an HMI or Human Machine Interface) built around a PC with a Windows operating system. This IS200VSVOH1BED VME Servo Board printed circuit board product offering's greater Mark VI Turbine Control System Series, as it is known at length, has to be considered quite the significant functional upgrade upon the previously-developed Mark V Turbine Control System Series of more or less the same full extended series title, as the Mark VI Series added the alternative energy-focused wind turbine application onto the rudimentary gas and steam turbine-based settings seen with the previous rollout of the Mark V.
Hardware Tips and Specifications
The IS200VSVOH1BED functions within the Mark VI system as a Servo Control board. The board controls four electro/hydraulic servo valves that drive fuel or steam valves. The valve position is measured using LVDTs, or linear variable differential transformers. A loop control algorithm is run using the IS200VSVOH1BED board. The IS200VSVOH1BED includes a single-slot front faceplate. This faceplate includes information like the manufacturer’s logo and the board number. The faceplate also includes several components, like a cable connector (J5,) and three LED components (Run/Fail/Stat.) The IS200VSVOH1BED is populated with over seventy integrated circuits. The board has various capacitors and resistors on its surface. TP test points are located in several locations. The board also has four relays on its back edge (K1 through K4.) The board has six connectors beyond the J5 connector in the front panel. This includes two backplane connectors and four connectors made from conductive traces. This IS200VSVOH1BED device is actually not the originally-developed device of its specific GE Mark VI Series intended functional role; that would have to be deemed the IS200VSVOH1 parent PCB notably not utilizing this IS200VSVOH1BED product's full three-fold revision table.
More information about the diagnostics, specifications, operation, and components of the IS200VSVOH1BED can be found in GE publication GEH-6421. This publication also includes installation guidelines. Unfortunately, this original Mark VI Turbine Control System Series instructional document has largely been scrubbed from the internet after a series of copyright infringements were faced by GE in the years past the Mark VI Series' original release. With this being the deal, the IS200VSVOH1BED functional product number itself stands to be adopted as a supplemental source of IS200VSVOH1BED VME Servo Board hardware component and component specification information,as it actually codes for a series of relevant IS200VSVOH1BED device qualities through a series of consecutive functional naming elements as developed by GE. For example, this IS200VSVOH1BED VME Servo Board functional product number is started off through a standard inclusion of the dual-functional IS200 series tag that indicates both this IS200VSVOH1BED VME Servo Board device's normal Mark VI Series assembly version as well as its domestic original GE manufacture location. Some of the other relevant IS200VSVOH1BED VME Servo Board PCB qualities indicated in this fashion include its:
- VSVO functional product acronym
- Group one Mark VI Series product grouping
- Conformal PCB coating style
- Three-fold revision history
