The SB3042 provides a fully floating dc supply for energizing a conventional 2- or 3-wire 4/20mA transmitter located in the field and
repeats the current in another floating circuit to drive a control-station load. For smart 2-wire transmitters, the SB3042 allows bi-directional
HART communications signals superimposed on the 4/20mA signal.
