Description
ABB PM866K01 3BSE050198R1 Process Controller for Industrial Automation
The PM866K01 3BSE050198R1 is a high-performance process controller designed by ABB for advanced automation systems, part of the AC800M Distributed Control System (DCS). Optimized for real-time monitoring and control in complex industrial environments, the PM866K01 supports a wide range of applications, including power generation, oil and gas, chemical processing, and water treatment.
1. Product Overview
The PM866K01 serves as the central processing unit (CPU) for ABB’s AC800M DCS, delivering 32-bit processing power and 128 MB RAM to handle up to 20,000 I/O points. It integrates Ethernet/IP, Profibus DP, and Modbus RTU protocols for seamless connectivity with field devices, HMIs, and third-party systems. With dual redundant power supply inputs (24 VDC/48 VDC) and -40°C to +70°C operating temperature range, it ensures continuous operation in extreme conditions.

6. Selection Recommendations
- System Compatibility: Pair with AC800M I/O modules (e.g., AI810K01) and 800xA HMI for full integration.
- Redundancy Needs: Choose PM866K01 redundant pairs for critical processes; use single controllers for non-critical applications.
- Environment: Opt for IP65-rated enclosures for outdoor or washdown areas.
- Scalability: Start with PM866K01 and expand I/O capacity via IMM100 communication modules.
7. Installation & Maintenance Notes
- Wiring: Use shielded cables for Profibus DP connections to minimize EMI interference.
- Cooling: Ensure adequate airflow (200–300 LFM) for continuous operation at high temperatures.
- Firmware: Update via ABB’s 800xA System Builder software to access advanced diagnostic tools.
- Safety: Disconnect power before replacing modules; wear ESD gloves to protect sensitive components.
