Description
ABB PM867K01 3BSE076355R1 High-Integrity Processor Unit
Product Introduction
The ABB PM867K01 3BSE076355R1 is a high-integrity processor unit for the ABB AC 800M controller platform used with System 800xA. It is designed for applications where conventional process control and high-integrity control functions must operate within a structured safety architecture. ABB specifies the PM867K01 at 133 MHz with 64 MB of memory and identifies it as a High Integrity controller. The processor is based on the MPC866 and delivers a stated performance of 0.09 ms for 1,000 Boolean operations.
The important distinction for procurement is that ABB PM867K01 3BSE076355R1 is not simply a higher-performance replacement for a standard AC 800M CPU. Its High Integrity capability is part of a defined architecture involving the PM867 processor, the SM812 safety module, and SIL-certified software. ABB documentation states that the PM867/SM812 combination can support High Integrity applications up to SIL 3 when configured according to the applicable safety manual. The PM867K01 package itself includes the PM867 CPU, TP830 baseplate, CEX-Bus and ModuleBus terminators, RCU-Link terminator, and memory-backup battery. It does not include a software license.
For existing AC 800M installations, ABB PM867K01 3BSE076355R1 should therefore be treated as a system-level controller component rather than an isolated CPU board. ABB lists built-in redundant Ethernet communication ports, while the PM867 baseplate also provides serial interfaces for controller-related functions. The documented package is compatible with 800xA 6.0.2 and later, making software and controller-version verification an important part of replacement planning.

Main Features and Engineering Considerations
1. High-Integrity Controller Architecture
The primary reason to specify the is its role in ABB’s AC 800M High Integrity architecture. ABB states that PM867 can be used with the SM812 module for High Integrity applications and that the resulting configuration can achieve SIL 3 certification when installed and configured in accordance with the safety documentation. The processor itself should not be treated as an independent SIL-rated controller simply because the catalog description says “SIL3.” The complete safety architecture, certified software, configuration, I/O, power arrangement, and application must satisfy the relevant safety requirements.
2. Package Contents Matter
The suffix K01 is important. ABB’s catalog defines as a processor-unit package containing the CPU and TP830 baseplate together with the required terminators and backup battery. It is not equivalent to purchasing only a loose CPU module. The K02 version is a different package containing two CPUs for redundant operation.
3. Ethernet and Serial Connectivity
The baseplate provides two RJ45 Ethernet ports for the Control Network. ABB’s data sheet also identifies two RJ45 serial ports, with COM3 providing RS-232C functionality and COM4 providing an isolated configuration-tool connection. This makes connector verification important when replacing an older AC 800M controller, particularly where cabinet wiring has been modified over several maintenance cycles.
4. Software Compatibility
ABB specifically states that is compatible with 800xA 6.0.2 and later. This is a procurement issue as much as a software issue. A physically correct controller can still create commissioning problems if the installed Control Builder, controller firmware, safety software, or application configuration is outside the supported combination. Check the existing engineering workstation and controller revision before ordering a replacement.
5. Redundancy Must Not Be Assumed
itself is listed as non-redundant. ABB separately identifies PM867K02 as the redundant High Integrity processor-unit package. If the existing installation uses controller redundancy, do not substitute a single K01 package based only on the fact that both use the processor. The package architecture and associated cables, baseplates, and configuration are different.
Application Scenarios
- High-integrity process control within ABB System 800xA
- Process plants requiring AC 800M High Integrity architecture
- Safety-related control applications using and SM812
- Oil and gas process control systems
- Chemical and petrochemical plants
- Power and utility process automation
- Existing AC 800M controller replacement and maintenance
- S800 High Integrity I/O control architectures
- Integrated business-critical and safety-related control environments where the certified ABB architecture is properly implemented
Engineer’s Guide: Field Pitfalls
Do not confuse with PM867K02. K01 is the single/non-redundant processor-unit package. K02 contains two CPUs and the associated redundancy hardware.
Do not treat “SIL 3” as a property of the CPU alone. The High Integrity solution depends on the SM812 safety module, certified software, correct system configuration, and the applicable safety lifecycle requirements.
Check the software baseline before installation. ABB specifies compatibility with 800xA 6.0.2 and later for this package. Firmware and Control Builder compatibility should be checked against the actual controller before removing the installed unit.
Verify the package contents. The K01 package includes TP830, TB850, TB807, TB852, and the backup battery. A supplier offering only a loose CPU should not automatically be represented as a complete package.
Check the battery condition. The package includes a lithium memory-backup battery. For stored spare inventory, inspect the battery condition and storage history before placing the unit into service.
Preserve the existing application configuration. A hardware replacement does not automatically reproduce the existing application, safety configuration, communication settings, or controller firmware. Back up the engineering project and verify the recovery procedure before a planned shutdown.
Frequently Asked Questions
What is ABB 3BSE076355R1?
It is an ABB AC 800M High Integrity processor-unit package. ABB specifies a 133 MHz processor with 64 MB memory and identifies article number 3BSE076355R1 as .
Is a PLC CPU?
Functionally, it is the processor/controller unit of the ABB AC 800M automation platform. It is more accurately described as an AC 800M High Integrity processor unit rather than a generic standalone PLC CPU.
Is SIL 3 rated?
ABB identifies the / High Integrity architecture as capable of SIL 3 certification when correctly configured. The should therefore not be considered an independently deployable SIL 3 safety controller without the required module, certified software, configuration, and safety-system requirements.
Does include the safety module?
No. ABB’s package includes the CPU, TP830 baseplate, terminators, and battery. The is a separate safety CPU module kit, article number 3BSE072270R1.
Does include a software license?
No. ABB explicitly lists the package as having no license included.
What is the difference between and PM867K02?
is the single processor-unit package. PM867K02 is the redundant package containing two CPUs plus the hardware required for the redundant arrangement.
What should be checked before purchasing a replacement?
Confirm the complete article number 3BSE076355R1, K01 package contents, installed 800xA version, controller firmware, application backup, arrangement, S800 High Integrity I/O configuration, communication interfaces, and cabinet/baseplate configuration. For safety applications, confirm the replacement against the approved system design rather than treating it as a simple like-for-like CPU swap.
Procurement Note
For procurement, specify the complete identification as ABB — 3BSE076355R1 — AC 800M High Integrity Processor Unit. Ask for confirmation that the supplied item is the K01 package rather than a bare CPU, and verify the included baseplate, terminators, and battery. ABB’s current documentation identifies the package as compatible with 800xA 6.0.2 and later.
For a plant replacement, the most important checks are exact article number, package configuration, controller firmware, 800xA/Control Builder version, configuration, application backup, and safety-system compatibility. Those checks matter more than simply confirming that the label says .
