The AC 800M controller is a family of rail-mounted modules, consisting of CPUs, communication modules, power supply modules and various accessories. There are 7 CPUs to choose from, ranging from medium processor power and low cost to high processor power and support for full redundancy.

The rich function block library includes several types of control loops, including advanced control and auto- tune capabilities as well as integration for ABB drives and motors. The controller communication by means of Ethernet includes on board RNRP redundancy along with a broad set of communication modules to connect to third-party devices. A superior redundancy concept allows for fast switch-over times and topologically separated CPU-modules. Several CPU modules are available, varying in terms of processing power, memory size and redundancy support. Priority controlled, time-based tasks allow the highest stability in even complex control tasks.

The 800M is an extremely powerful controller which is an integral part of the ABB 800xA platform and can also be used in conjunction with ABB CompactHMI and other third-party HMI’s.
