MTL4544B REPEATER POWER SUPPLY

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

The MTL4544B provides fully-floating dc supplies for energising two conventional 2- or 3-wire 4/20mA or HART transmitters located in a

hazardous area, and repeats the current in other circuits to drive two safe-area loads. For HART transmitters, the unit allows bi-directional

transmission of digital communication signals superimposed on the 4/20mA signal so that the transmitter can be interrogated either from

the operator station or by a hand-held communicator.
