The IS200EPDMG1B IS200EPDMG1BAA functions as an exciter protection board for turbines. This printed circuit board belongs to the Mark VI Speedtronic series from General Electric. The IS200EPDMG1B serves as the standard version for exciter protection circuits. Its variant, the IS200EPDMG1BAA, includes a conformal coating for enhanced circuit protection. Both boards manage exciter protection functions for steam and gas turbine generators.
Core Technical Specifications
This board provides multiple protection input channels for exciter monitoring. You will also find trip output channels for emergency shutdown. The board stores minimal energy but uses capacitors for signal filtering. Meanwhile, the backplane interface handles all power and data transfers.
