Loop Powered Current Transducer

Loop Powered Current Transducer Infographic

The QI-50-I is a Loop Powered Current transducer that provides a two-wire 4-20mA loop powered output. The QI-50I is designed to detect the True RMS value of the AC or DC current. It is DIP Switch selectable for either 0-25A or 0-50A full scale. The resolution is 12 Bit with an accuracy of 0.5%.
The 3000 Vac isolation between the input and the signal output eliminates the effects of all ground loops. It allows the use of the converter in heavy environmental conditions found in industrial applications. The current transformer can be mounted on a DIN Rail strip.
