Automatic switchover with maximum transfer time of approximately 10 ms

These features make it suitable for high-availability applications.

Lifecycle Status

ABB classifies PM864AK01 as a Classic AC 800M controller. Documentation indicates that for new installations, ABB recommends the newer PM866AK01 platform, while PM864AK01 and PM864AK01-EA are primarily supplied for maintenance, repair, and capacity upgrades of existing systems.

Typical Applications
Power generation
Oil & Gas
Petrochemical plants
Water and wastewater treatment
Pulp & paper mills
Mining and metallurgy
Pharmaceutical manufacturing
Continuous process industries

The PM864AK01-EA remains one of the most widely deployed AC 800M controllers in existing ABB 800xA systems due to its strong balance of processing performance, memory capacity, and redundancy support.
