Hi, this is my first post as Im a newbie please understand my lack of electronics knowledge!
I have a proportinal valve which requires a 200-800mA control signal the drive card for this valve doesnt exist any more so I have to make something. I want to control this with a 4-20mA output from a PLC. So the proposed circuit would amplify a 4-20mA input and give a 200-800mA output proporionaly. Any help with this would be great! thanks
