The MTL5541 provides a fully-floating dc supply for energising a
conventional 2- or 3-wire 4/20mA transmitter which is located in a
hazardous area, and repeats the current in another floating circuit to
drive a safe-area load. For smart 2-wire transmitters, the unit allows
bi-directional communications signals superimposed on the 4/20mA
signal.
