MTL5544D
MTL4544D – MTL5544D
REPEATER POWER SUPPLY
single channel, 4/20mA, HART®
for 2- or 3-wire transmitters, two outputs
The MTLx544D 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.
