The MTL4541P 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 circuit to drive a safearea load. For HART 2-wire transmitters, the unit allows bi-directional communications signals superimposed on the 4/20mA signal. The MTL4541P is a higher power version of the MTL4541B, usable for all gas groups provided that the field equipment is suitably certified.
