Yeah, I decided to use an "Arduino" 10MT "PLC" board as my I/O extender since it comes with optically isolated inputs, 4-20mA analog input and a 24VDC power input, all of which I can use. At the improbable price of $22.75!
- nick__m 3y agoThank you, I did not know about those PLC, it's incredible what you can obtain for that price.
