Hi,

Does anyone know of a HART communications bridge device that couples bi-directional HART communications between two different 4-20 mA current loops? Meaning, no DC signal coupling between the two loops, transformer isolation with bidectional gain in a single packaged device would nice for me.

Thanks,

So it's HART in and HART out? I think that makes it a repeater, not a bridge. If I'm reading you right, the handy thing about that is that it doesn't have to be HART specific. Any 4-20mA bi-directional repeater with sufficient bandwidth will do the job. That said, I don't know of any off the top of my head, but I'm sure they exist.
