Features:
- ABB lists the K02 package as two PM864AK01 units with TK850 and TK851 cables, so the complete redundant-kit identity must be distinguished from the single-processor 3BSE018161R1 package.
- The 96 MHz MPC862 and 32 MB RAM are per-CPU specifications; 23.522 MB is available for applications and the documented 0.15 ms benchmark covers 1000 Boolean operations.
- Redundancy supports the stated maximum 10 ms switchover and optical ModuleBus arrangement, while CEX-bus and Control Network connections must remain matched to the installed control-system configuration.
PM864AK02 3BSE018164R1 is the redundant processor kit built around two PM864A CPUs in ABB's AC 800M family. The manufacturer catalog specifies two PM864AK01 processor units plus a TK850 CEX-bus expansion cable and a TK851 RCU-Link cable. Each CPU uses a 96 MHz MPC862 processor with 32 MB RAM and 23.522 MB available for application programs and data. Redundant operation provides a documented maximum switchover time of 10 ms while retaining the per-controller processing and memory limits. The modular architecture connects Control Network Ethernet, CEX-bus communication modules and the optical ModuleBus I/O arrangement appropriate to a redundant pair. The controller is not a High Integrity safety CPU. PM864A is identified as Classic in the cited ABB outline; that historical phase designation does not by itself establish current discontinuation or a drop-in successor. Exact replacement selection therefore includes both CPU identities, controller software and the installed interconnection and I/O design.

The ABB PM864AK02 3BSE018164R1 is supported by Moore Automated for exact-item replacement and spare-part enquiries.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
3BSE018164R1 identifies PM864AK02, whereas 3BSE018161R1 identifies the PM864AK01 single-unit package. Check both PM864A labels and the documented TK850/TK851 interconnection scope when verifying a redundant-kit offer.
Each 96 MHz PM864A CPU has 32 MB RAM and 23.522 MB application space. A redundant pair runs within the per-controller resource limits; it is not a 64 MB shared-memory controller. Compare task load and communication demand with the installed application.
Use the redundant optical ModuleBus configuration and its 84-module limit. The CEX-bus supports up to 12 communication modules. Check interface compatibility and power budgets, and retain the documented Control Network and interconnection arrangement.
