MTL3041 REPEATER POWER SUPPLY, 4/20mA for 2-wire transmitters.

The MTL3041 provides a fully-floating dc supply for energising a 2- Load wire, 4/20mA transmitter in a hazardous area, and repeats the current accurately in another floating circuit to drive a load in the safe area. The 17.5V output (at 20mA) is more than sufficient for all normal transmitter loops, and the fact that it floats allows the field cables to be earthed, either intentionally or in error. The isolation of the safe-area circuit from the 24V dc supply allows systems to be wired without difficulty so as to eliminate measurement errors due to voltage drops in shared cables, and solves the problem of feeding control computers connected independently to earth as is sometimes demanded by their makers. The transformer-coupled circuit of the

MTL3041 chops the 4/20mA current directly, eliminating the need for any ‘high-stability’ resistors and ensuring extremely high long-term as well as short-term stability. For applications involving ‘smart’transmitters, use the MTL3046B.
