  • This product is a single-phase passive signal isolator, no external auxiliary power supply. The use of electromagnetic isolation principle, can isolated transmit DC 4 ~ 20mA signal of the input end to the output end for proportional. The input and output of the product are completely isolated from each other, and the output signal is linearly related to the input signal. It is widely used in signal isolation of a variety of 4-20mA current signal output end, reducer the various interference in site, Improve system reliability, can be applied to a variety of complex industrial site.
