MTL4541B REPEATER POWER SUPPLY 

4/20mA, HART®, for 2- or 3-wire transmitters 

The MTL4541B 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 safe-area load. For HART 2-wire transmitters, the unit allows

bi-directional communications signals superimposed on the 4/20mA loop current.
