Every now and then, you get asked a question that humbles you and makes you realize just how much more you've got to learn! I was just asked one of those questions... here it is?
"Does the attached Digital Output module supply the output you are expecting on your Input module?"
This is a contractor asking me if a new module they will be supplying in their new system will work with my 1756-IB16 modules to provide some DI's for us.
The "attached" as he calls it is attached. The .pdf doc refers to several different output types starting with CURRENT SINKING and so on...
My answer is ... only way I've ever wired these modules is dry contacts where it's looking at its own DC coming back. Please pass down any wisdom you may have.
