Product introduction
MTL5544S REPEATER POWER SUPPLY
Description
MTL5544S REPEATER POWER SUPPLY MTL5544S
Description
MTL5544S REPEATER POWER SUPPLY MTL5544S
The MTL5544S 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. MTL5544S For smart transmitters, the unit allows bi-directional transmission of digital communication signals superimposed on the MTL5544S 4/20mA loop current. Alternatively, the MTL5544S 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.
