Overview
Distribution power signal isolator, the circuit obtains power energy from the signal output end, isolates and converts the two-wire 4~20mA current signal at the input end into a 4~20mA current signal to the two-wire interface at the output end.
This product does not require an independent power supply, and the input and output are isolated.
