MTL5544D Repeater Power Supply

MTL5544D Repeater Power Supply, single channel, 4/20mA, HART for 2- or 3-wire transmitters, two outputs. The MTL5544D provides a fully-floating dc supply for energising a conventional 2- or 3-wire 4/20mA transmitter located in a hazardous area, and repeats the current in other circuits to drive two safe-area loads. For HART 2-wire transmitters, the unit allows bi-directional transmission of digital communication 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. Widely used in oil & gas, petrochemical, power generation, and process industries, the MTL5544D delivers reliable signal isolation and intrinsic safety protection for critical industrial applications.
