The IS200EISBH1A IS200EISBH1AAC functions as an exciter interface board for turbines. This printed circuit board belongs to the Mark VI Speedtronic series from General Electric. The IS200EISBH1A serves as the standard version for exciter signal interfacing. Its variant, the IS200EISBH1AAC, includes a conformal coating for enhanced circuit protection. Both boards interface excitation signals for steam and gas turbine generators.
Core Technical Specifications
This board provides multiple signal conditioning channels for exciter inputs. You will also find buffer circuits for signal isolation. The board stores minimal energy but uses capacitors for noise filtering. Meanwhile, the backplane interface handles all power and data transfers.
