  • ​ENTRIES:Part Number GuideData SheetFAQ
  • This device is a kind of DC current isolation transducer, adopts the principle of electromagnetic/treble isolation, can sample the DC current, and isolated output 0-5V, 0-20mA or 4-20mA standard signals, electrical isolation between input and output, between power supply voltage and input output, and  completely linear relationship between output signal and input signal. With characteristics of high precision, rapid response, high voltage isolation, low temperature drift, wide working temperature range, easy installation, comply with international standards. Can be widely used in real-time monitoring/monitoring of DC voltage signals, field data collection in computer scene, industrial control, PLC measurement and control, and a variety of automatic control system.
