The ABB PM865K01 (3BSE031151R1) is a High Integrity Processor Unit designed for the AC 800M controller platform within the ABB System 800xA environment. This unit is engineered for safety-critical process automation applications requiring high availability, deterministic control, and functional safety compliance. The processor is built around a 96 MHz PowerPC-based microprocessor, supported by 32 MB of RAM and 2 MB of Flash PROM for firmware storage.
Features
- High Integrity (HI) CPU capable of SIL 3 safety applications when used with compatible safety modules.
- Redundant controller architecture support for hot-standby configurations via RCU-Link.
- Integrated communication interfaces including two RJ45 Ethernet ports and two serial ports (COM3/COM4).
- CEX-Bus support for up to 12 communication modules, including PROFIBUS DP, Modbus TCP, and IEC 61850.
- Includes essential hardware kit: PM865 CPU, TP830 baseplate, TB850, TB807, and TB852 terminators.
Applications
- Chemical and material processing for continuous control loops.
- Water and wastewater management including pump station and filtration control.
- High-speed machinery coordination in packaging and textile industries.
- Material handling systems requiring cross-system synchronization via Ethernet.

Installation Guidelines
- Ensure the system is powered down before inserting or removing the processor module from the baseplate.
- Mount the TP830 baseplate securely to the DIN rail; ensure proper grounding to the cabinet chassis.
- Use shielded twisted-pair cabling for Ethernet connections to minimize EMI interference.
- Maintain adequate ventilation around the controller to ensure operating temperatures remain within the 0 to 55 degC range.
- For redundant configurations, ensure the RCU-Link cable (TK851) is correctly seated between the two PM865 units.
- Follow all specific safety manual instructions when configuring for SIL 3 functional safety.
