IS200EISBH1A

The IS200EISBH1A is a GE EX2100 and EX2100e Excitation Interface Signal Board serving as the primary signal interface within the EX2100 excitation control panel. The EISB receives signals from field-side measurement boards — including DC feedback circuits in the excitation bridge area — via fiber-optic links that provide voltage isolation and noise immunity between the high-voltage SCR bridge environment and sensitive control electronics. This isolation is critical in excitation systems where high-voltage thyristor bridges operate in close proximity to measurement and control circuits. A failed IS200EISBH1A can disrupt multiple signal paths simultaneously, affecting excitation feedback, protection functions, and control loop performance. Powergenics repairs and supplies the IS200EISBH1A with a 3-year warranty. Call 800-861-9773.
