MTL4541T Repeater power supply 4/20mA, 2- or 3-wire transmitters using long field lines
MTL4541T 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 HART 2-wire transmitters, the unit allows bi-directional communications signals superimposed on the 4/20mA loop current. Separately powered current sources, such as 4-wire transmitters, can be connected but will not support HART communication. The reduced maximum open-circuit voltage permits the use of longer field lines compared to MTL4541.
