This device is treble isolated DC voltage isolation transducer, adopts the principle of optoelectronic isolation to detect the DC voltage signals. Output linear 0~5V, 0~20mA or 4~20mA standard signals after isolation, this product implements a complete isolation between input and output, input and auxiliary power, auxiliary power and output. And with advantages of high precision, rapid response, high voltage isolation, low temperature drift, easy for installation, comply with international standards. Can be widely used in field data collection in computer scene, industrial control, PLC measurement and control, and a variety of automatic control system.
