The GE IS200VSVOH1BED is a cutting-edge printed circuit board (PCB) designed for use in General Electric's Mark VI system. As part of GE's renowned Speedtronic series, which dates back to the 1960s, the Mark VI represents the pinnacle of turbine management systems. This advanced system is used for gas and steam turbines and boasts integrated hardware and software capabilities, including Ethernet communication and a user-friendly Human-Machine Interface (HMI) built on a Windows-based platform.
Key Functions of the IS200VSVOH1BED
At the heart of the Mark VI system, the IS200VSVOH1BED serves as a Servo Control Board. Its primary role is to manage four electro/hydraulic servo valves that regulate the movement of fuel or steam valves. This process ensures precise control over turbine operations. The board utilizes Linear Variable Differential Transformers (LVDTs) to measure valve positions accurately, allowing a loop control algorithm to execute smoothly and efficiently.
Physical Features and Design
The IS200VSVOH1BED features a compact single-slot front faceplate, which includes essential identification details such as the GE logo and the board number. The faceplate also hosts key components, including:
- A J5 cable connector for external connectivity.
- Three LED indicators (Run, Fail, and Stat) that provide operational status.
The PCB itself is densely populated, boasting over 70 integrated circuits, capacitors, and resistors that enable its robust functionality. Test points (TPs) strategically positioned across the board simplify diagnostics and maintenance. Notable hardware elements include four relays (K1 through K4) along the back edge and six connectors, comprising two backplane connectors and four conductive trace connectors.
