Compatibilities between some S800 Module
We are preparing to purchase some spare parts for our ABB AC800F DCS, and we're looking for some informations regarding compatibility between some S800 modules:
CI840 and CI840A-eA
DO820 and DO820-eA
AO845 and AO845A-eA
Thanx for helping.
I think that are technically the same modules, when first belongs to 800xA product group and the second one is for Compact product (essential...).
The difference is the module color - first is almost white, the second one is grey.
I heard this different types in coding of the modules will not be used in the future
