ABB System 800xA era hardware — PM8xx controllers, CI8xx communication, S800 I/O and TB8/TK8 connection units.
System 800xA is ABB's current-generation process automation platform, built around the AC800M controller (PM851, PM857, PM858, PM863 and related PM8xx references), CI8xx communication interfaces, and the S800 I/O family (AI8xx, DI8xx, DO8xx modules on TB8xx and TK8xx connection units). It is one of the most widely deployed DCS platforms in power, oil & gas, chemicals and minerals processing.
The product pages here document controller performance classes, I/O module channel specifications and communication interfaces from the original documentation. Because 800xA projects couple controller firmware to the engineering database, the sourcing notes highlight firmware-revision checks and module compatibility within the S800 mounting sequence.
