2. Compatibility & Expandability

Same-brand Compatibility

ABB AI845 matches ABB AC800M DCS rack system. Site technicians install multiple ABB AI845 on system backplane to expand analog collecting points during facility reform. ABB AI845 plugs into standard rack slots and connects directly with ABB CPU and related base modules without auxiliary adapters. Dial code setup on module surface helps ABB AI845 coordinate with original ABB field sensors on production sites.

Cross-brand Compatibility

DCS exclusive bus structure blocks direct hardware connection of ABB AI845 to non-ABB control units. Additional protocol conversion modules are required to link ABB AI845 with PLC products from Siemens and Schneider. Global universal analog signal criteria allow ABB AI845 to access most third-party industrial transmitters with no inner circuit change.
