Description
Product Overview
PM867K01 (3BSE076355R1) is a single high integrity SIL3 certified processor unit for ABB AC 800M controller platform under System 800xA DCS. It executes safety and process control logic complying with IEC 61508, designed for safety instrumented applications. This package includes PM867 CPU, TP830 baseplate, terminators and memory backup lithium battery. It only supports ABB 800xA version 6.0.2 and above; PM867K01 is non-redundant single CPU variant, while PM867K02 is the redundant pair versionABB Group.

Key Features
- SIL3 High Integrity Safety Controller: Certified for safety functions, suitable for ESD, BMS and safety interlock control, separate from standard process controllerseero.
- Dual Redundant Ethernet Ports: Supports RNRP for network redundancy, communication with 800xA operator stations, historians and peer controllers.
- Comprehensive Built-in Diagnostics: Continuous monitoring of CPU, memory, bus and I/O communications, with fault logging and alarm reporting for safety function integrity.
- IEC 61131-3 Programming: Supports standard control languages including Function Block Diagram, Ladder Diagram and Structured Text for safety logic development.
- ModuleBus Interface: Connects to S800 series I/O modules for analog/digital signal acquisition and safety output control.
- Backup Lithium Battery: Preserves RAM application variables during temporary power loss; battery replacement required on scheduled maintenance cycle.
- Non-redundant Single Unit Package: PM867K01 is one standalone HI CPU assembly; select PM867K02 if hot standby redundant CPU pair is needed.
Applications
- Power plant boiler protection, turbine auxiliary safety interlock systems
- Petrochemical emergency shutdown (ESD) safety instrumented systems
- Chemical plant burner management (BMS) and fire & gas safety control
- Refinery process safety control cabinets
- Combined safety + basic process control for critical industrial assets
Installation & Maintenance Notes
- ESD protection is mandatory during CPU module handling.
- Lockout-tagout rack power before removing or inserting processor assembly.
- Backup safety application project and parameters in Compact Control Builder before spare replacement.
- Check lithium battery status periodically; low battery triggers diagnostic warning and risk of data loss upon power outage.
- Verify firmware revision compatibility with existing 800xA system version (minimum 6.0.2).
- Separate Ethernet/ModuleBus signal cables away from high-current power wiring to reduce EMI interference.
- After replacement, download safety application and perform full SIF (Safety Instrumented Function) loop test per safety manual.
- Confirm full part number PM867K01 / 3BSE076355R1 when ordering spare; do not confuse with redundant PM867K02.
FAQ
Q: What is the difference between PM867K01 and PM867K02? A: PM867K01 = single non-redundant SIL3 processor set. PM867K02 = complete hot-standby redundant pair with two CPUs, baseplates and interconnection cables for bumpless failover.
Q: Can PM867K01 run safety and normal process control together? A: Yes, it is High Integrity controller designed for safety functions; configuration must strictly follow ABB safety manual and IEC61508 lifecycle requirements.
