ABB PM863K01, order code
3BSE088381R1, is a single High-Integrity (HI) processor for the AC 800M controller platform under ABB Ability System 800xA.
Running on a 96 MHz processor with 32MB total RAM, it delivers fast logic execution with 0.17ms processing time for 1000 boolean operations. When paired with SM812 safety co-processor, this unit achieves TÜV IEC 61508 certification up to SIL 3. It enables integrated deployment of general process control and safety-related logic within one controller hardware, simplifying system architecture for ESD and burner management applications.
Equipped with dual Ethernet ports and serial communication interfaces, it supports seamless connection to S800 I/O stations and upper monitoring systems. The package includes TP830 baseplate, bus terminators and memory backup battery. Compatible with System 800xA V6.1 and Control Builder Safe 3 or later versions.
Commonly used in chemical, power and oil & gas plants. The exact part number 3BSE088381R1 is maintained as critical spare for safety DCS cabinet maintenance and system expansion.
Many process sites require unified hardware to handle both regular regulation control and safety interlock tasks, and the ABB PM863K01 (3BSE088381R1) addresses this demand as a High-Integrity processor module.
Unlike standard AC800M controllers, the PM863 HI series supports safety certified program execution. Built-in comprehensive hardware self-diagnostics continuously monitor CPU operation, helping operators detect faults before triggering safety trips. It supports CPU redundant configuration with maximum 10ms switchover time to enhance system availability.
The complete part identifier 3BSE088381R1 represents the standard single processor package with all matching baseplate and termination accessories. Direct drop-in replacement avoids complicated cabinet modification during maintenance.
A large number of facilities with System 800xA safety control systems keep this model in spare inventory to minimise downtime for safety loop overhaul and emergency CPU replacement.
