  • This device is an isolation transducer of power frequency signal detection. Using the optocoupler isolation and convert the input frequency signal into a linear output of 0 ~ 5V, 0 ~ 20mA, 4 ~ 20mA and other standard signals. This product uses two isolation methods that the input and output are isolated from the power supply. A variety range of input and output can be option, and built-in function switch free to choose. The product is simple to install, can be widely used in communications, electricity, railways, industrial control and other fields.
