This isolated barrier is used for intrinsic safety applications. It drives SMART I/P converters, electrical valves, and positioners in hazardous areas.
Digital signals are superimposed on the analog values at the field or control side and are transferred bi-directionally.
Current transferred across the DC/DC converter is repeated at terminals 1 and 2.
