MAC022 Series

Solid Core CT, 4 to 20mA Output, 21mm Cable Diameter or Busbar 20 x 10mm

Multirange current transformers, with loop-powered 4…20mA output (also called “passive”), are innovative products which permit to get a current measurement directly on a PLC or an acquisition system, without interposition of separated transducers and without auxiliary power connections. The electronic circuits, to transduce the measure and to generate the output signal, are actually integrated in the transformer housing, together with a miniature switch used to select one of the available ranges , and are powered with the same wires of the output. This means great cost reductions, very simple wiring and a generally improved reliability
