The IS200EDEXG1A IS200EDEXG1ABA functions as an exciter excitation control board. This printed circuit board belongs to the Mark VI Speedtronic series from General Electric. The IS200EDEXG1A serves as the standard version for excitation regulation. Its variant, the IS200EDEXG1ABA, includes a conformal coating for enhanced circuit protection. Both boards control excitation levels for steam and gas turbine generators.
Core Technical Specifications
This board provides multiple analog input channels for voltage and current feedback. You will also find control output channels for exciter regulation. The board stores minimal energy but uses capacitors for signal conditioning. Meanwhile, the backplane interface handles all power and data transfers.
