EEx d to EEx ia interface?

[cludwig]

All,
Sorry, to post two threads in a row... Is there a ready built and certified interface box for connecting an EEx d (flameproof) certified HART system to a EEx ia (intrinsically safe) system? I would either need a box with 4 zener barriers, or maybe just 1. (4 sensors on 1 loop or 4 sensors on 4 loops). The interface box must be EEx d certified.

I'm sure other guys have encountered this problem before. I am just hoping to save some time by finding a pre-built kit.

Thank you,
Chris.
