MTL 5500 Intrinsically Safe Isolators MTL5544
MTL4544/S – MTL5544/S REPEATER POWER SUPPLY 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.
