Three Keywords: Servo Control Board, Turbine Control Module, Industrial Control Spare Part

Product Details:

The GE IS200VSVOH1BDC, material part number MRP643486, is a high-performance VSVO Servo Control Board developed for GE Speedtronic Mark VI turbine control systems. This industrial control spare part is the core control board for electro-hydraulic servo valve regulation. As a reliable Turbine Control Module, it supports up to four servo valve control channels, receives LVDT position feedback signals from fuel valves and steam control valves, and outputs high-precision current drive signals to servo actuators. It executes fast closed-loop position control algorithms to precisely adjust valve opening, regulating fuel and steam flow to stabilize turbine speed and load. It needs to cooperate with TSVO servo terminal boards to form a complete servo control loop for gas turbines and steam turbines.

The GE IS200VSVOH1BDC Servo Control Board adopts conformal coated PCB to resist dust, moisture and vibration in harsh power plant environments. It integrates a 40MHz 32-bit DSP processor, 16-bit current command output and 12-bit feedback acquisition circuit. It has VME64 bus interface and RS232 service port for configuration and data exchange with main controller. Channel-to-channel isolation and surge suppression circuits protect the board from transient voltage interference. The board supports simplex, dual and TMR redundant system architectures and VME rack mounting inside Mark VI control cabinet. Built-in channel diagnostic functions can detect LVDT sensor faults, open circuit and abnormal servo drive signals. It is widely used in power generation and oil & gas industries for gas turbine, steam turbine control system maintenance, spare part replacement and system retrofit.
