I/O and Expansion Capability

The PM866K01 supports connection with ABB automation components including:

ABB S800 I/O modules
PROFIBUS DP communication interfaces
Fieldbus communication modules
AC 800M communication modules
CEX-Bus expansion units

Typical applications include large-scale process control systems requiring distributed I/O and reliable controller operation.

Redundancy Capability

Although PM866K01 itself is a single processor package, it supports ABB controller redundancy architecture.

For redundant controller configurations:

Two PM866K01 units are paired.
Communication redundancy can include:
CPU redundancy
CEX-Bus redundancy
Control network redundancy
S800 I/O communication redundancy

The ABB redundant package is designated PM866K02 (3BSE050199R1).
