IS200VSVOH1B Board assembly
The IS200VSVOH1B is a powerful VME servo control board that provides important support for the stable operation of gas turbine control systems by providing accurate servo control, position feedback, system communication and fault diagnosis functions.
The IS200VSVOH1B is a VME servo control board manufactured by General Electric (GE) for use in gas turbine control systems, particularly in the Mark VI control system. The main functions of the control board include:
Servo control: The IS200VSVOH1B acts as a servo control board to drive the fuel/steam valve by controlling the electro-hydraulic servo valve to achieve precise control of the gas turbine or other related equipment.
Position feedback: The board receives position feedback signals from a linear variable differential transformer (LVDT) to monitor and control the precise position of valves or other moving parts.
LVDT excitation: The IS200VSVOH1B provides the excitation signals required by the LVDT to ensure that the LVDT can function properly and produce accurate position feedback signals.
Pulse rate flow input: The board may also accept pulse rate flow input signals, which may be used to measure fluid flow or other related parameters to support more complex control strategies.
System communication: As part of the Mark VI control system, IS200VSVOH1B communicates with other system components to exchange data and control instructions, ensuring the coordinated operation of the entire system.
Fault diagnosis and protection: The control board may also have fault diagnosis and protection functions to detect abnormal conditions in the system, such as overcurrent, overvoltage, overheating, etc., and take appropriate measures to protect the system and equipment from damage.
Configuration and monitoring: The IS200VSVOH1B can be configured and monitored using the software tool provided by GE, allowing users to adjust control parameters as required, and view system status and control effects in real time on the operator interface.
