MTL4544AS CURRENT REPEATER Brand New with Good Discount 

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

The MTLx544 provides fully-floating dc supplies for energising two conventional 2-wire 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 smart transmitters, the unit allows bi-directional

transmission of digital communication signals superimposed on the 4/20mA loop current. Alternatively, the MTLx544S acts as a current

sink for a safe-area connection rather than driving a current into the load. Separately powered current sources, such as 4-wire transmitters,

can be connected but will not support HART communication.
