MRC022 TRMS Current Transformer with integrated Transducers hole Ø22 Selectable input 5÷30A with passive output 4-20 mA (2 wires technology) TRMS 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, which permit 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. The electronic circuits are powered with the same wires of the output. This means a great costs reduction, a very simple wiring and a generally improved reliability.
