Galvanic isolation removes the ground-loop currents from data lines; hence, the impressed noise voltage that affects the
signal also is eliminated. Common-mode noise can be removed completely and many forms of radiated noise can be
reduced to negligible limits using this technique.
It is highly recommended for use in high-noise environments.
