The IS200DSVOH1A IS200DSVOH1ABA functions as a servo valve output board for turbines. This printed circuit board belongs to the Mark VI Speedtronic series from General Electric. The IS200DSVOH1A serves as the standard version for servo valve control. Its variant, the IS200DSVOH1ABA, includes a conformal coating for enhanced circuit protection. Both boards control servo valve outputs for steam and gas turbine systems.
Core Technical Specifications
This board provides multiple servo valve output channels for precise positioning. You will also find feedback input channels for position verification. The board stores minimal energy but uses capacitors for signal smoothing. Meanwhile, the backplane interface handles all power and data transfers.
