Review ABB PM860AK01 capabilities, redundancy limits and AC 800M context. Compare controller families and prepare an accurate replacement-parts enquiry.
Editorial update · 3 September 2026 · Moore Automated
Compare the exact CPU.
Not just the family name.
PM860AK01 belongs to ABB’s AC 800M range. Its own capabilities—not features offered by other CPUs—must guide selection and replacement.

PM860AK01: the model-level facts
ABB’s hardware selector identifies PM860AK01 / 3BSE066495R1 as an AC 800M controller product. It lists a 48 MHz processor, 16 MB memory and Control Builder engineering support. Memory figures carry software-version conditions in the manufacturer’s record, so usable application capacity should be checked against the installed version and project.
This distinction matters when replacing a controller or comparing proposals. A requirement for redundant processing or a safety-related controller cannot be satisfied simply by choosing a product from the same family. Start from the application requirements and verify the exact candidate before discussing price or availability.
Compare architectures before specifications
AC 800M and the older Advant controller families should not be treated as one flat list of interchangeable CPUs. A useful comparison asks which engineering environment, I/O, networks and application records the plant already uses. Avoid comparing unsupported maximum I/O or memory numbers across unrelated configurations.
| Controller context | What to establish | Replacement implication |
|---|---|---|
| AC 800M | Exact CPU, Control Builder environment, installed I/O, communications and software version. | Select by model-level capabilities and documented compatibility. Family membership alone is insufficient. |
| Advant Controller 31 | Full controller reference, installed expansion arrangement, engineering tools and application backup. | Assess the existing architecture; do not assume an AC 800M unit is a direct replacement. |
| Advant Controller 110 / 160 | Installed platform, application requirements, interfaces and supported engineering workflow. | Define whether the task is an exact spare or a separately engineered migration. |
| Advant Controller 250 | Complete installed-system documentation and model-specific support information. | Determine a documented integration or migration route before selecting alternative hardware. |
A replacement review that goes beyond the CPU
Hardware fit
Confirm the complete order reference, revision, base or mounting arrangement, included accessories, communications and I/O context. Ask what is included in the quoted kit rather than assuming its contents.
Engineering fit
Check application and firmware compatibility, engineering access, licenses, backup quality and restore requirements. Include any required application conversion or configuration work.
Operational fit
Define the maintenance window, approved test scope, acceptance criteria and recovery plan. Installation decisions must follow the site’s engineering and safety procedures.
Procurement fit
Obtain actual-unit identification, declared condition, available inspection evidence and written delivery and warranty terms. A catalogue entry is not a stock reservation.

Keep the enquiry unambiguous
If the requirement is PM860AK01, state 3BSE066495R1 and provide the installed label and revision. If alternatives are acceptable, state the engineering requirements separately and require approval before substitution.
Link the component choice to lifecycle planning
A controller can be technically suitable yet difficult to recover quickly if the application backup, tools or compatible accessories are missing. Review the component and the recovery process together. For installed legacy systems, the Advant OCS maintenance and migration guide provides a broader assessment framework.
Do not infer a production-stop date from the controller’s age or a supplier’s inventory position. Obtain the relevant manufacturer lifecycle notice for the exact hardware and software scope. Compare a confirmed spare-parts route with the engineering and commissioning effort of any proposed migration, including the remaining operational life of the plant.
Frequently asked questions
01Does ABB PM860AK01 support CPU redundancy?
No. ABB’s model-specific hardware selector lists CPU redundancy as “No.” Capabilities of other AC 800M CPUs must not be applied to PM860AK01.
02Is PM860AK01 a High Integrity controller?
ABB’s hardware selector marks High Integrity as “No” for this model. Do not select it for a requirement merely because a different AC 800M product offers that capability.
03Are PM860A and PM860AK01 identical purchasing descriptions?
The processor designation and an ordering-kit reference are not sufficient substitutes for a complete quotation. Confirm the exact article number and the included components against the requirement.
04Can PM860AK01 directly replace an Advant Controller 31 or 110/160?
Do not assume a direct replacement. Different controller architectures can require application, I/O, network and engineering changes that must be evaluated as a migration.
05What should a controller comparison include besides memory?
Include required functionality, redundancy, I/O and network compatibility, software and engineering tools, recovery capability and the scope of commissioning work.
06What should I send to request PM860AK01?
Send the complete reference, installed label and revision, quantity, required condition, included-accessory requirements, destination and delivery date. Identify any mandatory inspection or documentation scope.
