PRODUCT INFORMATION
Product Overview
The General Electric IS200VSVOH1B is a VSVO Servo Control Board designed for Mark VI turbine control systems. It acts as an electro-hydraulic interface to drive fuel and steam valves across turbine installations. The board directly controls up to four electro-hydraulic servo valves. It provides position loop control, LVDT excitation, and LVDT position feedback. Additionally, the assembly processes pulse rate flow inputs for turbine valve positioning.
Engineers can deploy the IS200VSVOH1B in Simplex or Triple Modular Redundant control architectures. The board mounts in a single slot and includes front-panel diagnostic light-emitting diodes. A green RUN LED indicates normal operation. A red FAIL LED signals hardware faults. An orange STATUS LED illuminates during an active alarm condition. Six onboard connectors provide backplane routing and trace connections for field signals.
