The IS200EPCTG1A IS200EPCTG1AAA functions as an exciter contact terminal board for turbines. This printed circuit board belongs to the Mark VI Speedtronic series from General Electric. The IS200EPCTG1A serves as the standard version for contact termination. Its variant, the IS200EPCTG1AAA, includes a conformal coating for extra circuit protection. Both boards terminate exciter contact signals for steam and gas turbine generators.
Core Technical Specifications
This board provides multiple contact input channels for exciter status monitoring. You will also find output channels for contact control signals. The board stores minimal energy but uses capacitors for contact debouncing. Meanwhile, the backplane interface handles all power and data transfers.
