MTL5541 MTL Repeater Power Supply Better than 15µA 1.58 cm x 10.98 cm x 12.36 cm

MTL5541 MTL Instruments Repeater Power Supply

The MTL5541 provides a fully-floating dc supply for energising a conventional 2- or 3-wire 4/20mA transmitter, which is located in a hazardous area, and repeats the current in another floating circuit to drive a safe-area load. For HART 2-wire transmitters, the unit allows bi-directional communications signals superimposed on the 4/20mA loop current.
