ABB PM866AK02 3BSE081637R1 Redundant Processor Unit
Manufacturer: ABB
Product Number: PM866AK02 (3BSE081637R1)
Category: Redundant Processor Unit
Architecture: Dual CPU
System Compatibility: ABB AC 800M automation system
Communication: CEX-bus
Application: Critical industrial applications requiring high-reliability redundant processing
Product Description
The ABB PM866AK02 3BSE081637R1 is a high-reliability redundant processor unit designed for the ABB AC 800M automation system. Engineered for critical industrial applications, the PM866AK02 features dual CPU architecture and advanced CEX-bus communication, ensuring continuous operation even during component failures. With a 133 MHz MPC 866 processor and 64 MB memory (51.389 MB available for applications), it delivers fast processing (1,000 boolean operations in 0.09 ms) and supports up to 96 I/O modules (single configuration) or 84 modules (redundant setup). The unit includes dual Ethernet ports (RJ45), RS-232C interfaces, and redundant power supply inputs, making it suitable for distributed control systems (DCS) in industries like energy, manufacturing, and infrastructure. Part of ABB’s AC 800M series, the PM866AK02 offers IP20 protection, CE/UL certification, and seamless integration with 800xA Control Builder software.
Product Parameters
| Parameter | Specification |
|---|---|
| Brand | ABB |
| Model | PM866AK02 3BSE081637R1 |
| Type | Redundant Processor Unit (AC 800M Series) |
| Processor | MPC 866, 133 MHz |
| Memory | 64 MB (51.389 MB application RAM) |
| Redundancy | Dual CPU, CEX-bus, and I/O support |
| Communication | Ethernet (10 Mbps), RS-232C (2 ports), Profibus DP |
| Power Supply | 24 V DC (19.2–30 V DC), 210/360 mA (typ/max) |
| Backup Battery | Lithium-ion (3.6 V) for memory retention |
| I/O Capacity | 96 modules (single) / 84 modules (redundant) |
| Cycle Time | Down to 1 ms (32 tasks per controller) |
| Protection Class | IP20 (dust/water-resistant without housing) |

Advantages and Characteristics
- High Availability: Redundant CPU architecture with <10 ms switchover time (IEC 61508-compliant for safety-critical systems).
- Flexible Connectivity: Dual Ethernet ports and segmented CEX-bus (BC810/BC820) for scalable I/O and communication.
- Industrial Hardening: Operates in -40°C to +70°C (storage) and 5–95% humidity (non-condensing), with G3 corrosion resistance (ISA 71.04).
- Energy Efficiency: Low power consumption (5.1 W typical, 8.6 W max) with redundant power input.
- Ease of Maintenance: Slide & Lock mechanism for quick DIN rail installation; remote diagnostics via HART/OPC.
- Certifications: ISA Secure certified for cybersecurity and marine compliance (DNV-GL, ABS, BV).
Application Fields and Application Cases
Industries: Power generation (coal/natural gas plants), oil & gas (refineries), water treatment, and automotive manufacturing.
Use Case:
Power Plant DCS: Installed in a 500 MW coal-fired plant, the PM866AK02 managed redundant control of boiler-turbine systems, achieving 99.99% uptime over 5 years. Its dual Ethernet ports and 1 ms cycle time minimized communication delays, reducing unplanned outages by 35%.
Competitor Comparison
Compared to similar redundant processors:
- Faster Redundancy Switchover: <10 ms (vs. 15–20 ms in legacy models).
- Higher I/O Density: 84 modules (redundant) vs. 60–70 modules in competing products.
- Enhanced Cybersecurity: ISA Secure certification (vs. basic security in standard units).
- Longer Warranty: 3-year standard (vs. 1–2 years industry average).
Selection Suggestions
- Redundancy Needs: Choose the PM866AK02 for systems requiring 24/7 operation (e.g., power plants); opt for single CPU models (e.g., PM866A) for non-critical applications.
- Communication Protocols: Ensure compatibility with existing networks (Ethernet, Profibus DP).
- Environment: Verify temperature range (+5°C to +55°C operating) and corrosion resistance (G3) for harsh environments.
- Scalability: Plan for future I/O expansion (max 96 modules in single mode).
- Software: Use ABB 800xA Control Builder for configuration and redundancy setup.
Precautions
- Power Stability: Maintain 19.2–30 V DC input; avoid voltage spikes (surge protection recommended).
- Heat Management: Ensure adequate airflow (IP20 requires external enclosure in dusty/wet environments).
- Redundancy Configuration: Follow ABB’s guidelines for dual CPU synchronization (CNCP protocol).
- Battery Replacement: Replace lithium-ion batteries every 5 years (part no. 4943013-6) to prevent memory loss.
- EMI Shielding: Use shielded cables for Ethernet/serial connections in high-noise areas.
- Firmware Updates: Regularly update firmware (via Com 4 port) to patch security vulnerabilities.
