The IS200EMCSG1AAB is a small board with few components. It functions as a Conduction Sensor and has four conduction sensors built into the front half of the board.
The IS200EDEXG1A board receives power from the ESPM module, the power that should be received from that module should be 24 VDC; the EDEX module will then turn the power received into 125 VDC.
