Re: [foxboro] HART on I/A -- thoughts?

Doesn't look like it.  Rather, I'm guessing Foxboro found it deficient at 
installation number 2 or 3 and so came up with an extra balun module that 
performs the isolation by brute force and extra rack space.  You need 2 of 
them for an 8-input HART AI card.

Rather than some electronics types solely designing these things, they 
need to get some of us users involved.  I still think that the first plant 
I/E guy that goes and starts a DCS company will make a killing...

Re: [foxboro] HART on I/A -- thoughts?






So, is there an galvanically isolated HART input card?  Cause, uhh, I 
didn't realize that this was just group isolated, and that kind of 
sucks.  See I was hoping to avoid, "is usually only found to be 
deficient at installation and is a pain to fix."

Just wondering.
