ABB AC 800M Controller Hardware
A redundant PM863 processor package for ABB AC 800M High Integrity applications, with the CPU pair and specified RCU/CEX interconnection cables.
ABB PM863K02, article 3BSE088382R1, is a redundant High Integrity processor package for AC 800M safety applications. The kit supplies two PM863K01 processors and the specified interconnection cables; SM812, SIL-certified software and the applicable ABB Safety Manual remain required for the approved safety solution.
| Model / article number | PM863K02 / 3BSE088382R1 |
|---|---|
| Package configuration | Redundant High Integrity processor kit |
| High Integrity | Yes |
| Processor type / clock | MPC866 / 96 MHz |
| Memory | 32 MB |
| Redundant switch-over | Maximum 10 ms |
| Power supply | 24 VDC; permitted range 19.2–30 VDC |
The PM863 is intended for High Integrity controller use. ABB identifies PM863 with SM812 for SIL 1–2 supervision and for the diverse 1oo2 architecture used in SIL 3 applications. The required certified software and project rules remain part of the safety lifecycle.
Do not commission, modify or replace safety hardware from part-number similarity alone. Validate the approved hardware set, SM812 arrangement, software release, safety application, proof-test requirements and change-control records against the ABB Safety Manual.
| Official package contents | 2 × PM863K01 safety processor units; 1 × TK850 CEX-Bus expansion cable; 1 × TK851 RCU-Link cable |
|---|---|
| Processor redundancy link | TK851 RCU-Link cable |
| CEX-Bus connection | Both CPUs connect to the same CEX-Bus through TK850 or through BC810/BC820 |
| S800 I/O in redundant configuration | Optical ModuleBus through two TB840 units |
| Electrical ModuleBus with redundant CPUs | Not used |
| SM812 safety module | Required for High Integrity safety functionality; ordered/configured separately according to the approved design |
During a processor change, preserve the documented primary/backup roles, cable routing, hardware positions and safety-project baseline. After installation, use ABB procedures for firmware, application download and redundancy verification.
Used where the approved AC 800M High Integrity BOM identifies this redundant processor package. Procurement records should include the safety project and release baseline.
Inspect TK851, both processor states, firmware alignment and redundant project configuration before removing hardware.
Treat safety-module or certified-application indications through the ABB Safety Manual and site safety procedures; do not bypass them for production.

| Dimensions per processor (W × H × D) | 119 × 186 × 135 mm |
| TÜV approval | Yes |
| Operating temperature | 0 to +55 °C (+32 to +131 °F) |
Commercial supply support, separate from ABB technical documentation.
Documented receiving and packing checks for High Integrity spares.
Part number and visible condition reviewed.
Available testing stated on the quotation.
Protective packing and prompt issue review.
Terms confirmed before the order is placed.
These part numbers are independent purchasing references only. They are not replacements for the product on this page. Compatibility and stock must be confirmed separately for each item.
No. Certified safety functionality requires the approved SM812 arrangement, SIL-certified software and configuration under the ABB Safety Manual.
The official package contains two PM863K01 processor units, one TK850 CEX-Bus cable and one TK851 RCU-Link cable.
Use optical ModuleBus through two TB840 units in the redundant configuration; the built-in electrical ModuleBus is not used.
ABB specifies a maximum of 10 ms for the redundant processor configuration.
No. Hardware, firmware, certified application, proof-test and site approval records must follow the governing ABB safety documentation and plant procedures.
Provide the part number, quantity, destination, required date, machine/system model, System 800xA and safety-software releases, SM812 details and nameplate photos.
For a faster technical and commercial check, send the installed-part details before the requested ship date.
