The Qi-50-I is a Loop Powered Current transducer that provides a 2 wire 4-20 mA loop powered output. It is designed to detect the TRMS value of the AC or DC current. It is DIP Switch selectable for either 0-25 A, or 0-50 A full scale. The resolution is 12 Bit with an accuracy of 0.5%. The 3000 Vac isolation between input and the signal output eliminates the effects of all ground loops and 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. The Baud-rate and address can be set by DIP switches.
