GE IS200EDCFG1BAA Exciter DC Feedback Board

The IS200EDCFG1BAA Exciter Dc Feedback Board (EDCF) is used in the EX2100 Excitation Control. It measures field current and field voltage at the SCR bridge, and interfaces to the EISB board in the control panel over a high-speed fiber-optic link. The fiber-optics provides voltage isolation between the two boards, and high noise immunity. Two fibers are used, one for each signal. There are two types of fibers which can be used for different distances, as follows:

• Plastic type fiber for distances up to 10 m 

• Hard clad silica type for distances up to 90 m
