Dear customer, the MTL5000 range product model MTL5043 has been discontinued. The MTL5500 range MTL5544D is the replacement product for MTL5043.

MTL5043 barrier product specification:

MTL5043 REPEATER POWER SUPPLY dual output, 4/20mA, for 2-wire ‘smart’transmitters.

The MTL5043 provides a fully floating dc supply for engergising a conventional 2-wire 4/20mA ‘smart’ transmitter which is located in a hazardous area, and repeats the current in two floating circuits to drive two safe-area loads. HART is repeated through channel 1 only for bi-directional communication.

MTL5544D product specification:

MTL4544D – MTL5544D REPEATER POWER SUPPLY single channel, 4/20mA, HART® for 2- or 3-wire transmitters, two outputs

The MTLx544D provides a fully-floating dc supply for energising a conventional 2- or 3-wire 4/20mA transmitter located in a hazardous area, and repeats the current in other circuits to drive two safe-area loads. For HART 2-wire transmitters, the unit allows bi-directional transmission of digital communication signals superimposed on the 4/20mA loop current. Separately powered current sources, such as 4-wire transmitters, can be connected but will not support HART communication.
