4-20mA Current Loop isolator deign

[masoud1234]

hi all
I want to design a circuit that has an input of 4-20 mA(loop power) and 4-20 mA output with input and output isolation

You could achieve that using www.vishay.com/docs/83622/il300.pdf

How do I design a circuit 4-20 mA loop power with IL300
input 4-20ma loop power
output 4-20ma isolat
thanks

I believe that this is your task, I'm not going to provide you a ready circuit, I have just pointed you to a component you can use to achieve what you want.

Check the datasheet example and modify it to your needs.
