About the IS200EACFG1A
The Exciter AC Feedback Board under the part number IS200EACFG1A is part of the EX2100 Series manufactured by General Electric Company. This specific model is a G1 version of the IS200EACFG modules. The G1 version of this module can support an individual three-phase input voltage and will have a nominal range of 480 VRMS with a positive twenty percent at fifty to sixty hertz.
The IS200EACFG1A module is also labeled within the EX2100 Series as an input/output terminal board. The module also handles most of the bridge AC voltage and current feedback as it measures the exciter power potential transformer (PPT) AC voltage supply. There are three transformers contained within the board that will measure voltage for three phases. The IS200EACFG1A can connect to an EBKP backplane model. When connecting the IS200EACFG1A and EBKP backplane boards a cable no longer than ninety millimeters in length will connect the boards. The three screw connectors which are labeled TB1, TB2, and TB3, on the IS200EACFG1A model are strictly used for voltage inputs.
On the IS200EACFG1A there are three 9-pin connectors which are J504, J509, and J514, the connectors are used for the cables which will connect the EBKP backplanes for the EMIO boards.
