Features:
- 96 MHz PM864A processing with 32 MB RAM and 23.522 MB available for application execution
- 2 integrated Ethernet channels plus support for 12 CEX-Bus communication modules in the documented controller layout
- Redundant CPU operation with maximum 10 ms switch-over and maximum 96 non-redundant or 84 redundant i/o modules through the verified ModuleBus arrangement
ABB identifies PM864AK01 3BSE018161R1 as a 96 MHz PM864A processor unit in the AC 800M controller family. It provides 32 MB RAM, including 23.522 MB available for the application, and uses the MPC862 processor architecture documented by ABB. The unit supports 2 Ethernet channels, up to 12 CEX-Bus communication modules and maximum 96 non-redundant or 84 redundant i/o modules. CPU redundancy and a maximum 10 ms switch-over are supported in a correctly engineered pair. Selection must be based on the complete 3BSE018161R1 article number, CPU type, control-software version and installed bus configuration.
Technical values are taken from ABB AC 800M controller and processor-unit documentation. Final compatibility is confirmed against article number 3BSE018161R1, the installed controller nameplate and the project hardware configuration.
The ABB PM864AK01 3BSE018161R1 AC 800M processor unit is supported by Moore Automated for verified industrial replacement and spare-part requirements.

PM864A Processing Profile
The PM864A CPU runs at 96 MHz with 32 MB RAM and supports the documented AC 800M control and communication workload.
Redundant Pair Requirements
Both processor units in a redundant pair must match the approved hardware and software configuration; verify the RCU-Link and switch-over design.
Classic-to-New Controller Review
For a new installation, ABB directs users toward PM866AK01; confirm software, memory, interfaces and migration scope before replacement.
