1、 Introduction to the performance of current input isolation safety barrier at the detection end

Provide isolated working power supply to transmitters in hazardous areas, while detecting the current in the circuit, and output current or voltage signals to the safe area through isolated transmission. The three terminal isolation of input, output, and power supply has the advantages of fast response, low power consumption, and good temperature characteristics.
