MeloAuto-Trusted PLC & DCS Parts Supplier
The GE IS200AEADH4A and GE IS200AEADH4ADA serve as reliable input terminal boards for exciter systems. These modules belong to the Mark VI series from General Electric. They provide termination points for field wiring from sensors and transducers. Consequently, these boards simplify connections to the exciter control system.

Functional Design and Signal Termination
The GE IS200AEADH4ADA connects directly to the exciter backplane of the cabinet. It accepts low-level analog signals from field sensors. Then, this board passes conditioned signals to the analog input module. Each channel includes a low-pass filter for noise rejection. Therefore, the IS200AEADH4A provides clean signals for accurate control calculations.
Installation and Compatibility Notes
You must tighten all terminal screws before powering up the system. The GE IS200AEADH4A fits exclusively into Mark VI series exciter cabinets. Always replace faulty units with identical GE board revisions. Additionally, verify the sensor wiring matches the terminal labels. This practice prevents signal reversal and measurement errors.
