Application Area

Typical Use

Redundant Process Control

PM867K02 is suitable for continuous process units where controller availability is an important design requirement. Its synchronized processor pair provides primary and backup operation with a specified maximum switch-over time of 10 ms.

High Integrity Control Architectures

The processor pair can form part of an ABB High Integrity system when combined with the appropriate SM812 configuration and software. The complete design must follow ABB’s applicable engineering and safety instructions.

Critical Equipment Interlocking

The controller can execute permissives, equipment sequencing and coordinated shutdown logic for critical plant assets. Redundant processing reduces dependence on a single CPU, while the final response still depends on communication and I/O architecture.

Redundant Distributed S800 I/O

PM867K02 supports up to seven optical ModuleBus clusters in a redundant CPU configuration. It can accommodate a maximum of 84 redundant ModuleBus I/O modules, subject to project topology and scan-time requirements.
