High-Performance SIL3-Capable Processor for Safety-Critical & Redundant Control Applications

Brand: ABB

Product Family: AC 800M / System 800xA

Model Numbers: PM863K01 (3BSE088381R1) , PM863K02 (3BSE088382R1)

Product Type: High-Integrity (HI) Controller / Redundant Processor Unit

Product Overview

The ABB PM863K01 and PM863K02 are powerful, high-performance controller units belonging to the ABB AC 800M series, designed for integration into the ABB Ability™ System 800xA Distributed Control System (DCS).

As the central processing core of an automation station, the PM863 series combines robust real-time control with High-Integrity (HI) functionality. This unique capability allows a single controller to handle both standard process automation and safety-critical tasks (up to SIL 3) without sacrificing performance . The key distinction between the two models lies in their configuration: the PM863K01 is a single-processor unit, while the PM863K02 is a factory-assembled redundant package containing two PM863K01 units, cables, and mounting hardware for high-availability applications .

Key Features & Differentiators

High-Integrity (HI) Architecture

The PM863 is certified to IEC 61508 SIL 3 by TÜV. By adding an SM812 safety module and SIL-certified software, the controller can run safety logic and standard control logic on the same hardware platform, reducing complexity and cost for Emergency Shutdown Systems (ESD) and Burner Management Systems (BMS) .

Flexible Redundancy Support (PM863K02)

For mission-critical processes requiring maximum uptime, the PM863K02 package provides a complete 1:1 redundant CPU solution .

Package Includes: 2x PM863K01 units, 1x TK850 CEX-Bus cable, 1x TK851 RCU-Link cable .

Redundancy Scope: Supports CPU, CEX-Bus, communication interfaces, and S800 I/O .

Robust Communication Interfaces

The controller base plate is equipped with versatile connectivity options for modern industrial networks :

CN1 & CN2: Two RJ45 Ethernet ports for connection to the dual-redundant Control Network.

COM3: RS-232C serial port with modem control signals.

COM4: Isolated serial port for configuration tool connection.

Modular & Rugged Design

Designed for harsh industrial environments, the PM863 offers a compact footprint (119mm x 186mm x 135mm) with an IP20 protection class, allowing easy DIN-rail mounting and integration into existing S800 I/O chassis .
