Product Introduction
The PM865K02 CPU module comes fully equipped for high-availability automation systems. Included in the package are the CPU unit itself plus redundancy components, enabling seamless deployment into dual-CPU control architectures. With twice the RAM of many mid-level modules (64 MB) and sub-millisecond processing, it delivers both power and reliability.
This redundancy-ready configuration makes life easier for engineering teams: fewer additional purchases, fewer integration steps, and more assurance that the control system won’t let them down. Its design accommodates ABB’s S800 I/O, CI extensions, and fieldbus systems, giving it broad compatibility.
