Description
Product Overview
The ABB PM860AK01 3BSE066495R1 is a processor unit package in the AC 800M controller family, designed for industrial automation applications requiring programmable control, communication with operator and supervisory systems, and coordination of distributed I/O. ABB specifies an MPC860 processor running at 48 MHz, with 16 MB of memory. The package is non-redundant, so it should not be treated as a redundant controller pair or as a high-integrity safety controller.
The controller’s baseplate provides two RJ45 Ethernet ports for the control network and two serial interfaces. COM3 supports RS-232C communication with modem-control signals, while COM4 is isolated and intended for connection to a configuration tool. The controller supports AC 800M engineering environments, including System 800xA Control Builder and Compact Control Builder. Its documented configuration also supports communication modules on the CEX bus and local or optical ModuleBus I/O expansion, subject to the controller’s capacity limits and installed configuration.
When sourcing the ABB PM860AK01 3BSE066495R1, confirm whether the purchase includes the complete processor unit package or only the CPU. ABB’s package description includes the PM860A CPU, TP830 baseplate, TB850 CEX-bus terminator, TB807 ModuleBus terminator, and memory-backup battery; a software license is not included. Before replacing an installed controller, verify the engineering software version, firmware compatibility, application memory requirements, network addresses, serial-port assignments, and connected CEX-bus modules. The controller is non-redundant, so maintenance planning should account for the effect of removing it from service. For used stock, request actual-unit photographs and test records, and confirm that the included accessories match the order description.
Product Introduction
The ABB PM860AK01 3BSE066495R1 is a 48 MHz AC 800M processor unit with 16 MB memory, two Ethernet channels, and two RS-232C interfaces. It is supplied as a defined controller package with the baseplate and bus termination accessories.
For replacement planning, check firmware and Control Builder compatibility, application memory usage, connected I/O, and network settings before installation. The non-redundant design should also be considered when scheduling a controller outage.

Frequently Asked Questions
Q1. What is the ABB 3BSE066495R1 used for?
It is an AC 800M processor unit used to execute control applications and communicate with connected I/O and control-network devices in supported industrial automation systems.
Q2. Does the package include the baseplate and bus terminators?
ABB’s documented package includes the PM860A CPU, TP830 baseplate, TB850 CEX-bus terminator, TB807 ModuleBus terminator, and a memory-backup battery. Confirm the contents of the specific item being supplied.
Q3. Is a redundant controller?
No. ABB specifies as non-redundant. Do not assume it provides automatic processor failover.
Q4. Which engineering software is supported?
ABB documents configuration through System 800xA Control Builder or Compact Control Builder. Confirm the exact software release and controller firmware compatibility for the installed system.
Q5. Can be replaced directly with PM862K01?
Not without a compatibility review. The PM862K01 has different processor and memory specifications, and ABB documents specific engineering-software prerequisites for that model. Check the application, firmware, and system release before changing controller types.
Q6. Does the package include a software license?
No. ABB’s package description explicitly states that no license is included. Confirm separate license requirements with the site’s system administrator or engineering documentation.
Q7. What should be checked before ordering a used or refurbished unit?
Verify the full order number, CPU and baseplate identity, package accessories, physical condition, and available test records. Also establish whether the application can be restored and whether firmware and engineering-tool versions are compatible before scheduling the replacement.
