Typical Use

Redundant Process Control

PM866AK02 can be used in continuous process applications where controller availability is an important design requirement. The paired processors can execute sequencing, interlocking, regulation and equipment-control functions within an engineered AC 800M redundancy configuration.

Plant Utility Automation

The package can control steam, cooling-water, compressed-air, water-treatment and other plant utility systems. Its application capacity allows several utility sections and execution tasks to be coordinated within the same controller project.

Large Distributed-I/O Systems

CEX-Bus and optical ModuleBus resources support installations with communication interfaces and geographically distributed I/O clusters. ABB specifies up to 84 ModuleBus I/O modules for a redundant PM866 configuration.

Production and Material-Handling Control

PM866AK02 can coordinate production sections, conveyors, equipment permissives and operating sequences where loss of the primary controller should initiate transfer to the redundant controller path.
