ABB 3BSE018100R1 PM860K01

The ABB PM860K01 (3BSE018100R1) is a Processor Unit Kit for the ABB AC 800M controller platform within the System 800xA automation environment. It is designed to provide the central processing function for industrial process-control applications. ABB documentation identifies the product as a processor unit kit and indicates that it is no longer for sale. 

Core Functions

PM860K01 performs the central control and processing functions of an AC 800M controller, including:

• Execution of control applications and automation logic
• Real-time processing of process data
• Communication with I/O and control-system components
• Support for modular AC 800M system configurations
• Connection to CEX-bus and ModuleBus architectures
• Program and configuration storage through the controller's memory/CompactFlash interface

The PM860 processor uses an MPC860 processor architecture. Available technical documentation specifies 24 V DC nominal power supply, with an operating range of approximately 19.2–30 V DC. 

Design Features

The PM860K01 is supplied as a complete processor-unit package rather than simply as an individual CPU board. According to ABB's product documentation, the package includes the processor, baseplate, bus terminators, memory-backup battery, and power plug. 

Its modular design makes it suitable for integration into AC 800M control architectures where reliable processor operation and communication with distributed I/O are required.

Hardware Composition

The standard PM860K01 package contains:

These components are explicitly listed in ABB's product documentation for 3BSE018100R1. 

Typical Applications

PM860K01 can be used in industrial automation and process-control installations based on ABB AC 800M, including:

• Power generation and distribution
• Oil and gas processing
• Chemical and petrochemical plants
• Water and wastewater treatment
• Pulp and paper production
• Manufacturing and process industries
• Existing System 800xA installations requiring replacement processor hardware

Maintenance Considerations

Because PM860K01 / 3BSE018100R1 is listed by ABB as no longer for sale, it is particularly relevant as a replacement or maintenance spare for existing AC 800M installations. 

When sourcing a replacement, verify the complete kit contents and part number. The backup battery should also be checked as part of preventive maintenance, especially for long-installed systems.

Overall Evaluation

The ABB PM860K01 3BSE018100R1 is a complete AC 800M Processor Unit Kit, combining the PM860 CPU with the required TP830 baseplate, CEX-bus and ModuleBus terminators, backup battery, and power connector. Its primary value today is as a maintenance and replacement component for existing ABB AC 800M / System 800xA installations, particularly where the original processor configuration must be maintained.
