ABB PM857K02 3BSE088386R1 Redundant Processor Unit HI — AC 800M High Integrity
PM857K02 is ABB's redundant High Integrity processor package for the AC 800M platform. The ABB configuration combines two PM857K01 Safety Processor units with the TK850 CEX-bus expansion cable and TK851 RCU-Link cable. For purchasing and replacement checks, use the complete article number 3BSE088386R1.
PM857K02 at a glance
PM857K02 belongs to ABB's AC 800M High Integrity range and is identified as a Redundant Processor Unit HI. The K02 ordering reference is significant because it describes the redundant package rather than a single processor unit.
The package is built from two PM857K01 Safety Processor units and includes the cables specified by ABB for the package. The High Integrity configuration must be engineered in accordance with the applicable ABB safety documentation.
When searching for a PM857K02 pdf, the complete reference 3BSE088386R1 should be retained alongside the model designation.

Check the installed High Integrity configuration first
ABB-stated environment
Part-number distinction
The K02 package structure
The package contents are particularly relevant when matching a spare against an installed controller or purchasing record. Confirm the complete ABB article number rather than ordering only by the PM857 family name.
Where PM857K02 enters the maintenance search
High Integrity controller
Used in ABB AC 800M High Integrity configurations where the redundant PM857 processor arrangement is part of the engineered safety system.
Redundant processor replacement
Customers may search the exact article when an installed PM857K02 package requires a spare and the single PM857K01 must not be confused with the complete K02 package.
Processor or redundancy fault
Controller hardware or redundancy-related faults can become a maintenance priority because an affected safety-control installation may require controlled intervention before normal operation can continue.
