The IS200GGXIG1A IS200GGXIG1AED functions as a generator excitation interface board. This printed circuit board belongs to the Mark VI Speedtronic series from General Electric. The IS200GGXIG1A serves as the standard version for excitation control signals. Its variant, the IS200GGXIG1AED, includes a conformal coating for extra circuit protection. Both boards manage generator excitation for steam and gas turbine systems.
Core Technical Specifications
This board provides multiple analog input channels for excitation feedback. You will also find output channels for exciter field control. The board stores minimal energy but uses capacitors for signal filtering. Meanwhile, the backplane interface handles all power and data transfers.
