Greetings, my problem is this.
I am interfacing a plc with a vfd. The problem I am having is that the vfd signal out is a 4-20ma loop and the plc card takes a 0-5 volt signal.
What could I use to convert a 4-20ma signal to a 0-5 volt one.
(I was thinking of a Fet and a battery and having the 4-20 control the voltage through put through the fet.)
Any suggestions welcome
Thank you,
Derek
