MTL4541B Repeater Power Supply 4/20Ma, Hart®, For 2- Or 3-Wire Transmitters
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 signal.
MTL4541B is MTL4041B replacement.
