S900 CI920 compatibility

Hello,

I would like to know if I´m working in classified area ATEX zone 2, can I use CI920A type S (for hazardous area ATEX zone 1 and zone 2) with I/O modules type B (for hazardous area ATEX zone 2 only), for exemple DX910B ?

Regards

As per the manual---

Do not mix components of different types. All components (termination unit, power units, Communication Interfaces and I/O modules) must be of the same type.

Yes, i have read this in the manual too, but in spite of that information, i would like to know if it is possible to comunicate one type with another.

mixing up the components may lead to certification issues. Therefore, my advise is that you shall contact sales / presales personnel in your region to take it up with product management. By the way, may I know, why do you intend to mix it ? Have you bought items wrongly or you want to utilize available hardware with you ?

I have bought wrong CI920 for this area, all I/O cards are type B.

I did check with product management and as per their reply, From functional (i.e. from SW) point of view, the mixed combination (‘S’ system CI920A combined with ‘B’ system CI920A) should work. But a mix (even if the zone 1 equipment would be used for zone 2 installations) would lead to confusion and it would be potential source of hazard and not the least is prohibited by the certification document. It might be that an certified expert might find a way to get the combination certified for zone 2 applications, but this would mean effort, documentation and the willingness of the Ex-expert at site to accept, i.e. approve such a consideration.
In short, as stated earlier, it's not supported by Product Management.
