Product Description

The PM851K01 (3BSE018168R1) serves as a high-performance central processing unit within the ABB AC 800M controller family. It is designed to execute complex control strategies, manage industrial communication protocols, and interface seamlessly with the S800 I/O system.

The “K01” designation indicates a complete kit version, typically including the processor unit, baseplate, and required mounting components for immediate DIN-rail installation.

Equipped with integrated Ethernet ports and serial interfaces, the PM851K01 supports industrial communication protocols such as MMS and PROFINET (via configuration and system integration). The rugged aluminum enclosure functions as a passive heat sink, eliminating the need for forced-air cooling in standard industrial environments and enhancing long-term reliability.

Technical Specifications

Application Scenarios

The PM851K01 is widely deployed within System 800xA environments for mid-range automation tasks, including:

  • Water and wastewater treatment control

  • Industrial HVAC and building automation

  • Secondary process control in petrochemical plants

  • Utility and energy distribution subsystems

It provides reliable real-time logic execution for systems that require solid performance without full CPU redundancy.

Functional Comparison

Compared to the PM860 series, the PM851K01 offers a cost-effective entry solution for applications that do not require controller redundancy.

While it maintains full compatibility with Control Builder M and the AC 800M firmware architecture, it is optimized for:

  • Lower I/O counts

  • Moderate communication loads

  • Less memory-intensive control strategies

For high-availability or redundant CPU architectures, the PM86x series is recommended.
