PM864AK01 availability, lead time and order review
Send RFQProduct Introduction
PM864AK01 is the single-processor AC 800M kit built around the PM864A CPU. It includes the baseplate, bus terminators, RCU-Link terminator and memory-backup battery required for the processor unit.
Engineering note: ABB records PM864A as a Classic-lifecycle controller. Before migration, compare the 800xA release, redundancy pair, CEX-Bus and ModuleBus design—not only CPU speed and memory.

Compatibility & Replacement
Confirmed replacement. ABB lifecycle information identifies PM862K01 (3BSE076940R1) as the replacement type for PM864AK01.
Migration conditions. ABB states that PM858 and PM862 can be used from System 800xA 6.0.2 and that both processor modules in a redundant pair must be the same type. Treat migration as an engineered controller change.
Applications & Fault Scenarios
Redundant controller design
Supports a paired CPU arrangement where short switchover time protects continuous-process availability.
CPU will not reach normal state
Check 24 V supply, baseplate seating, bus terminators, firmware/project compatibility and retained diagnostic indications.
Redundancy unavailable
Confirm both CPUs are the same approved type, inspect RCU-Link hardware and compare primary/backup controller states.
Controller communication loss
Separate Ethernet, CEX-Bus and ModuleBus symptoms; one failed path should not be diagnosed as a total CPU failure without evidence.
Independent spare-parts support
Amikon can review the exact part number, installed system, quantity, destination and required date before quotation.
Pre-outage checkpoints
- Back up the control project and firmware record.
- Record primary/backup state and RCU-Link status.
- Inventory CEX-Bus modules and ModuleBus I/O clusters.
- Confirm 800xA release before any PM862 migration.

PM864AK01 FAQ
Should an ABB PM864AK01 enquiry state whether the controller is single or redundant?
Yes. State the installed AC 800M arrangement and whether the requirement concerns one processor or a redundant pair. Redundancy hardware must be reviewed as a complete configuration.
Does ABB PM864AK01 automatically mean that every base and accessory is included?
No. Kit contents are quotation-specific. Request a written list of the processor, baseplate and any additional included items before ordering.
Can current stock, condition and lead time for ABB PM864AK01 be confirmed from this page?
No. Stock, condition, inspection scope and lead time change by offer and must be confirmed in the live quotation for ABB PM864AK01.
What pre-shipment evidence can I request for ABB PM864AK01?
Request clear label, condition and serial-number photos plus the agreed inspection or testing record for ABB PM864AK01 before dispatch.
How should I submit an urgent shutdown requirement for ABB PM864AK01?
Send the exact part number, quantity, destination, required date, machine or system model and failure context. Priority routing starts after the ABB PM864AK01 identity is confirmed.
What DOA, return and warranty terms apply to ABB PM864AK01?
They are defined in the quotation. If ABB PM864AK01 arrives DOA or does not match the purchase order, report the serial number, label, packaging and fault evidence promptly for after-sales review.
