GE IS200EDFFH1A IS200EDFFH1ABA DC Feedback Board

The GE IS200EDFFH1A and GE IS200EDFFH1ABA function as dedicated DC fanned feedback boards for exciter systems. These modules belong to the Mark VI series from General Electric. They monitor and report DC voltage levels from multiple power sources. Consequently, these boards provide critical feedback for exciter control and protection.

Functional Design and Feedback Monitoring

The GE IS200EDFFH1ABA connects directly to the exciter backplane of the cabinet. It accepts DC voltage inputs from field power supplies. Then, this board scales and filters each signal for accurate measurement. Each channel includes a precision voltage divider for high input impedance. Therefore, the IS200EDFFH1A provides reliable feedback without loading the monitored circuit.

Installation and Compatibility Notes

You must verify voltage ratings before connecting to this feedback board. The GE IS200EDFFH1A fits exclusively into Mark VI series exciter cabinets. Always replace faulty units with identical GE board revisions. Additionally, check the scaling factors against your system configuration. This practice ensures correct voltage readings on the main controller.
