MTL4544B MTL4044 replacement original isolated barrier

MTL4544B REPEATER POWER SUPPLY 2-channel, 4/20mA, HART庐, 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.
