ABB PM866K01 (3BSE050198R1) AC 800M Redundant Processor Unit for Industrial Process Control

Product Description

The ABB PM866K01 (Ordering Number: 3BSE050198R1) is a factory-integrated high-performance redundant processor unit designed exclusively for the ABB AC 800M controller platform, part of the ABB 800xA industrial automation system. As the core processing component for critical process control applications, this rugged processor unit features a high-speed control-optimized CPU, 64 MB RAM+51 MB Flash memory (with CompactFlash expansion slot), dual 10/100Base-TX Ethernet ports for control network redundancy, dual serial (RS-232C) ports for configuration and diagnostics, CEX-Bus/ModuleBus/RCPU-Link support for I/O expansion and controller redundancy, and 24 VDC isolated power input. Certified for -40°C to +70°C wide-temperature operation, IP20 front-panel protection, industrial-grade EMI/RFI shielding, and hot-swap compatibility, it delivers uninterrupted control for power generation, oil & gas, chemical processing, and manufacturing industries requiring SIL-compliant, fault-tolerant process automation.

Key Functions

The PM866K01 redundant processor unit delivers mission-critical process control with these core features: High-performance control processing for complex IEC 61131-3 logic (LD/FBD/SFC/IL/ST), advanced PID, and APC algorithms; Full controller-level redundancy (CPU, CEX-Bus, Ethernet networks, and I/O buses) for zero-downtime failover; Dual 10/100 Ethernet ports for redundant control network connectivity; CompactFlash slot for program backup, data logging, and firmware upgrades; Isolated 24 VDC power input with overvoltage/overcurrent protection; Hot-swap compatible design for module replacement without system shutdown; Built-in diagnostics, LED status indicators, and INIT pushbutton for troubleshooting; Support for Profibus-DP, Modbus TCP/IP, and other industrial protocols via expansion modules, ensuring seamless integration with intelligent field devices and third-party systems.

Application Scenarios

The ABB PM866K01 (3BSE050198R1) is optimized for critical process control applications requiring redundant, fault-tolerant performance, including: Oil & gas upstream/midstream processing plants with HART/Foundation Fieldbus intelligent devices; Chemical and petrochemical refineries with SIL 2/3 safety instrumented systems (SIS); Power generation facilities (thermal, hydro, nuclear) with turbine/boiler control and plant-wide automation; Water/wastewater treatment plants with SCADA integration and process optimization; Pharmaceutical manufacturing with batch control and FDA-compliant data logging; Retrofit projects for legacy ABB AC 800M/800xA systems upgrading to redundant processor configurations for increased availability.
