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.
3BSE088386R1 Redundant Processor Unit HI 96 MHz 32 MB Max. 128 I/O signals
01 / Overview
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.

High Integrity controller environment
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.
05 / Application & Fault Search
Where PM857K02 enters the maintenance search
01 / SAFETY CONTROL
High Integrity controller
Used in ABB AC 800M High Integrity configurations where the redundant PM857 processor arrangement is part of the engineered safety system.
02 / SPARE MATCH
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.
03 / DOWNTIME
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.
06 / Delivery & Warranty
Order terms, kept simple
Part-number check PM857K02 / 3BSE088386R1 checked against the quotation request.
Inspection Available test or inspection information is confirmed according to the actual unit supplied.
Packaging Packaging and unit condition are confirmed before shipment.
DOA / Warranty DOA handling and warranty coverage follow the agreed quotation and order terms.
07 / FAQ & RFQ
PM857K02 ordering questions
What is included with ABB PM857K02?
ABB identifies PM857K02 as a redundant package containing 2 pcs PM857K01 Safety Processor units, 1 TK850 CEX-bus expansion cable and 1 TK851 RCU-Link cable.
Is PM857K02 the same as two separately ordered PM857K01 units?
The K02 ordering reference represents ABB's defined redundant package. For a spare-parts purchase, confirm the required article number rather than assuming that two PM857K01 units constitute an interchangeable order.
Which 800xA environment is listed for PM857K02?
ABB documentation identifies compatibility with 800xA 6.1 and Control Builder Safe 3 and onwards. The actual installed software and High Integrity configuration should be checked before replacement.
What should I send when requesting a PM857K02 quotation?
Send the complete article number 3BSE088386R1, required quantity, destination, required date and the installed machine/system model. This helps verify the correct spare configuration before quotation.
Can PM863K02 be used as a direct replacement for PM857K02?
No automatic substitution should be assumed. PM863K02 is a different ABB redundant High Integrity processor package. The installed controller, software environment and approved configuration must be checked before considering any replacement.
