RCV420: Implementation on RCV420

Hi Ryan,

Attached below is a pdf file with a presentation covering 4-20mA Current Transmitter basics.  The presentation provides the contrast between the 2-wire and 3-wire transmitters.

In addition, below there is a blog series that discusses the 4-wire configuration:

Hello Luis

Thanks for the detailed explanation. It really solve my questions. 

There're 2 photos and is it suitable for voltage output & circuit output sensor?

Thank you for the big help
