About the IS200EDCFG1B
Exciter DC Feedback Board IS200EDCFG1B is part of the Excitation Controller series produced by General Electric Company USA. This model is connected to a DC shunt which provides the output feedback. The IS200EDCFG1B board is part of the high voltage interface system. This model is also part of the I/O terminal boards, and this board mainly controls the DC outputs and feedback, as well as current voltages.
The field voltage feedback circuit of the EDCF model provides a total of seven settings on the selector, these settings scale down the bridge voltage, but this all depends on the application that the bridge is set to. The fiber-optic cables that are connected to the IS200EDCFG1B model provide an isolated voltage between the EISB board and the EDCF board, along with high noise immunity.
The field current feedback from your IS200EDCFG1B model is measured across the DC shunt that is located at the SCR bridge. When the field current is running as it should it will generate a low-level signal, that has a maximum value of 500 MV, which will be the input to a different amplifier.
The best manual to use when using the IS200EDCFG1B model is the GEH-6632 EX2100 Excitation Control User’s Guide, information regarding the EDCF model can be found on pages fifty and sixty-four.
