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. 

Frequently Asked Questions about IS200EDCFG1B

The IS200EDCFG1B board has a P1 connector. What are the pin descriptions for this connector?

The P1 connector has two pins. Pin one if a field current and voltage shunt feedback positive connection, note that the entry side of the DC shunt is also the SCR Bridge Positive. Pin two is a field current shunt feedback return connector. 

There are ten jumpers on the IS200EDCFG1B board. What are the descriptions of the JP3 and JP7 jumpers?

The JP3 jumper is labeled as 400 PPT V with the description being bridge voltage scale jumper, insert for PPT voltage of 400 VRMS. The JP7 jumper is labeled as POF HCS with the description being the type of fiber-optic cable for Current Feedback Output, POF stands for plastic optic fiber for ten meters of distance and HSC stands for hard-clad silica fiber for ninety meters of distance. 

If three redundant EDCF boards gave been installed can the exciter continue running if one board has failed?

Yes! If only one board has failed the exciter can continue running, but it should be noted that due to the high voltages the failed EDCF board cannot be replaced while online. 

The IS200EDCFG1B board has an E1 connector what is the description for this connector?

The E1 connector is only one pin and is described as a field voltage feedback negative connection.
