ABB PM867K01 PM867K02 AC 800M High-Integrity Process Controllers SIL3

Order Codes: 3BSE076355R1 (PM867K01) / 3BSE081638R1 (PM867K02)

Brand: ABB

Product Family: AC 800M High-Integrity

Type: Redundant Processor Unit / Safety Controller

Product Overview

The ABB PM867K01 and PM867K02 are high-performance process controller units belonging to the AC 800M High-Integrity series. Designed for mission-critical Distributed Control Systems (DCS) such as ABB System 800xA, these controllers combine complex process control with functional safety.

By pairing the PM867 with an SM812 safety module, the system achieves IEC 61508 SIL3 certification . This allows the PM867 to run standard control logic and safety logic on the same hardware platform without compromising integrity, making it the ideal solution for industries requiring high availability and fail-safe operations.

The key difference between the two models is that PM867K02 includes the necessary hardware and licenses for CPU redundancy (Redundancy Package), whereas PM867K01 is typically sold as a single (non-redundant) unit or as part of a redundant pair .

Redundancy & High-Integrity Configuration

Why choose PM867K02?

The PM867K02 is specifically packaged for redundant applications. It includes components required to set up a 1oo1 or 1oo2 architecture . If one CPU fails, the system automatically switches to the backup unit, ensuring continuous process availability.

High-Integrity (SIL3) Setup:

To activate the safety functionality, the PM867 must be combined with an SM812 module . This setup provides intelligent supervision of the controller during non-SIL and SIL1-3 operations, forming a 1oo2 diverse structure for the highest safety levels .

Applications & Use Cases

The ABB PM867 series is widely used in industries requiring both complex automation and stringent safety oversight:

Oil & Gas: Emergency Shutdown Systems (ESD) and Fire & Gas (F&G) systems.

Power Generation: Turbine control and boiler safety management.

Chemicals & Petrochemicals: Batch process control and high-pressure reactor safety.

Pharmaceuticals: Critical process control requiring audit trails and data integrity.

Metallurgy: Furnace control systems requiring high availability.

Installation & Maintenance

Installation:

The PM867 mounts onto a dedicated base plate (e.g., TP830). For redundant setups, specific RCU-Link cables (TK851) and CEX-bus cables (TK850) are required to synchronize the two CPU units .

Maintenance:

The controller features LED status indicators (Power, Run, Fault, Comm) for real-time diagnostics . It supports remote diagnostics via the 800xA system. In redundant mode, the faulty unit can be replaced via hot-swap without shutting down the process.
