Features:
- PM858K01 is the 3BSE082895R1 processor package, using a 33 MHz MPC866 with 16 MB total RAM and 7.147 MB for the application.
- The controller supports the documented 1 electrical + 7 optical ModuleBus layout and communicates through 2 x 10 Mbit/s RJ45; project loading must remain within the stated controller limits.
- CPU redundancy is supported with a maximum 10 ms switchover; the redundant layout uses 7 optical clusters and the complete kit or matching partner hardware must be verified.
PM858K01 3BSE082895R1 is an ABB AC 800M processor unit built around the PM858 CPU. Its MPC866 runs at 33 MHz with 16 MB RAM and 7.147 MB available to the application. The documented package comprises one PM858 CPU with the required processor-unit base and termination items. It is a standard process-control CPU rather than a High Integrity safety processor. The 24 VDC processor supports up to 12 CEX-bus modules. Local I/O uses 1 electrical + 7 optical clusters in single operation and 7 optical in a redundant arrangement, subject to 96 / 84 I/O modules. Control Network communication is provided through 2 x 10 Mbit/s RJ45 using MMS and IAC. Selection must preserve 800xA 6.0.2 / Compact Control Builder 6.0.0-1 and later, the installed project, CPU generation, partner hardware and bus topology.
Before replacing PM858K01 3BSE082895R1, record the installed position, hardware revision, mounting or connector arrangement, paired assemblies and every applicable ABB service record. Compare the supplied unit with the original item and approved configuration, isolate all relevant energy sources, and follow the documented installation procedure. After installation, inspect every affected mechanical, electrical and communication interface and complete controlled functional checks before returning the equipment to service.
The PM858K01 3BSE082895R1 ABB Processor unit is listed as Active / Available from OEM. Current revision, availability and supplied scope are confirmed in the written quotation.

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.
The PM858K01 3BSE082895R1 package contains one PM858 CPU with the required processor-unit base and termination items. Check the order number and every supplied item because a bare CPU or a different K01 generation is not the same product scope.
Each PM858 CPU uses a 33 MHz MPC866 with 16 MB RAM and 7.147 MB application space. The 0.36 ms Boolean benchmark is not the complete process-loop response time.
The processor accepts up to 12 CEX-bus modules and uses 1 electrical + 7 optical clusters in single operation. The redundant layout is 7 optical; apply the 96 / 84 I/O modules limit and verify 800xA 6.0.2 / Compact Control Builder 6.0.0-1 and later.
