MTL Safety Barriers Repeater Power Supply MTL5042 

Description

The MTL5042 provides a fully-floating dc supply for energising a conventional 2- or 3-wire  /20mA transmitter which is located in a hazardous area, and repeats the current in another floating circuit to drive a safe-area load. For smart 2-wire transmitters, the unit allows bi-directional communications signals superimposed on the 4/20mA signal.
