MTL5544/MTL5544s - Repeater Power supply

Analogue Input modules
The analogue input (AI) modules support 2-wire or 3-wire 4/20mA or HART transmitters located in
a hazardous area; repeating the current in other circuits to drive safe-area loads.
MTL5544/MTL5544s - Repeater Power supply
Two channel, for 4/20mA HART® for 2- or 3-wire transmitters
The MTL5544 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 HART transmitters, the unit allows bi-directional transmission
of digital communication signals superimposed on the 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. Seperately powered current sources, such as 4-wire transmitters, can be connected but will
not support HART communication.
