Panelview Touchscreen - Ex ia (Intrinsically Safe)

[matt6 0]

Hi, Just wondering if anyone could help me out? I was talking to another engineer at site and he was saying he heard that there was an Allen-Bradley Panelview screen which could be installed within a Distribution and Control Box (DCB) / Load Centre (essentially a Ex d (Flameproof) enclosure) which has touchscreen capabilities. The DCB is located in the hazardous zone and is therefore explosion protected. He couldn't remember who told him of this and after looking on Rockwell's website I'm out of answers. My question is, is this even possible? The screen would need to be mounted within the Ex d (Flameproof) enclosure behind a viewing window and touch screen sensor would be mounted externally on the viewing window and have to be Ex ia (Intrinsically Safe). The application is within an underground coal mine in NSW, Australia. Thanks in advance.
