relay

can you have multipe relay stages,and each subsequently able to handle more power?

What are the four generally recognized parts of a PLC?

The hardware required to interface a PLC with a 4-20mA loop as an input?

Sounds like a school assignment to me...

hunter1,

When you were an even younger lad, did that cute little girl next door ever take you behind the woodshed and whisper in your ear: I'll show you mine if you show me yours first?
