The transformer-coupled isolation amplifier uses separate power supplies for the input and output stages, which are isolated by virtue of the individual transformer windings. This provides the input and output stages with decoupled ground or common returns. In addition, the modulator/demodulator transfers the measured signal across the barrier via other transformer windings for complete galvanic isolation between input and output.
