Product Introduction

PM861AK01 is the single-processor AC 800M kit based on the PM861A CPU. The package includes the TP830 baseplate, CEX-Bus, ModuleBus and RCU-Link terminators, plus a memory-backup battery.

Engineering note: ABB records PM861A as a Classic-lifecycle controller with replacement available. Migration must preserve controller release, redundancy pairing and the engineered I/O/communication architecture.

Compatibility & Replacement

Lifecycle status. ABB lists PM861AK01 as a Classic-lifecycle CPU with replacement available and identifies PM858 among the newer controller series for PM861A/PM864A migration.

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. Confirm the exact replacement package in the ABB lifecycle plan for the installed project.

Applications & Fault Scenarios

01

AC 800M process control

Executes control applications and manages local, optical and CEX-Bus resources in an AC 800M controller station.

02

Redundant controller service

Supports paired CPUs where loss of the primary processor should transfer control to the healthy partner.

03

CPU remains in fault or stop

Capture LEDs and controller diagnostics, then check power, firmware/project compatibility, baseplate and bus termination.

04

Backup CPU unavailable

Verify both processors are the same approved type and inspect RCU-Link hardware and redundancy synchronization.

05

Intermittent I/O or network alarms

Separate CPU, Ethernet, CEX-Bus and ModuleBus symptoms before replacing the processor; each path has its own diagnostics.

AMIKON SUPPORT

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 project and firmware record.
  • Record primary/backup state and RCU-Link status.
  • Inventory CEX-Bus modules and ModuleBus I/O.
  • Confirm the ABB lifecycle migration package for this project.

PM861AK01 FAQ

What must be checked when buying ABB PM861AK01 for a redundant CPU pair?
Confirm that both processors in the redundant pair are the same approved type and review the installed RCU-Link and project context against ABB documentation.
Can ABB PM861AK01 be ordered by processor family name alone?
No. Use the full PM861AK01 identity, article information and installed AC 800M configuration; closely related processor variants should not be treated as interchangeable.
Can current stock, condition and lead time for ABB PM861AK01 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 PM861AK01.
What pre-shipment evidence can I request for ABB PM861AK01?
Request clear label, condition and serial-number photos plus the agreed inspection or testing record for ABB PM861AK01 before dispatch.
How should I submit an urgent shutdown requirement for ABB PM861AK01?
Send the exact part number, quantity, destination, required date, machine or system model and failure context. Priority routing starts after the ABB PM861AK01 identity is confirmed.
What DOA, return and warranty terms apply to ABB PM861AK01?
They are defined in the quotation. If ABB PM861AK01 arrives DOA or does not match the purchase order, report the serial number, label, packaging and fault evidence promptly for after-sales review.
