ABB PM864AK01 (3BSE018161R2) – High‑performance AC 800M CPU for 800xA process automation

The ABB PM864AK01, order code 3BSE018161R2, is the PM864A CPU kit for the AC 800M controller family used in ABB 800xA systems. From my experience, it’s the go‑to option when a plant needs more processing headroom, tight cycle times, and robust redundancy. You might notice that it integrates neatly with S800/S900 I/O via communication modules, so there’s no need to rethink your I/O strategy when upgrading or replacing legacy PM8xx units.

Order Placement Process and Guarantees

• Warranty: 365 days
• Delivery: typically 1 week if in stock; no more than 1 month at the latest
• Payment: 50% advance payment; full payment prior to delivery
• Express options: FedEx, UPS, DHL

Key Features

• High‑speed AC 800M CPU (PM864A) – Designed for complex control strategies and larger I/O counts without stretching scan times.
• 800xA integration – Works with Control Builder M Professional and fits right into existing 800xA architectures.
• Redundancy‑ready – Typically supports CPU redundancy (with SM801 and appropriate modules) for high availability applications.
• Dual Ethernet for control network – In many cases, two 10/100 Mbps Ethernet ports are available for network segregation or RNRP‑based networks.
• No onboard field I/O – Clean separation of control and I/O; connect to S800/S900 I/O via communication interfaces.
• Industrial temperature range – Suitable for standard cabinet environments in most process plants.
• Lifecycle continuity – Common toolset, firmware strategy, and accessories help reduce commissioning risk.

Technical Specifications

Application Fields

The PM864AK01 is used across continuous and batch process industries where deterministic control and system uptime matter. Typical scenarios include:

• Oil & Gas – compressor stations, gas processing, pipeline control rooms
• Chemicals & Petrochem – reactor sequencing, utility balance, safety interlocks (with separate safety systems)
• Power & Water – boiler/HRSG control, desalination trains, water treatment
• Metals & Mining – grinding/flotation, material handling, drive coordination
• Pulp & Paper – machine sections, stock prep, steam and condensate systems

One thing I appreciate is how easily it drops into existing 800xA networks; in many cases you can preserve your I/O racks and just modernize the controller side to recover performance headroom.

Advantages & Value

• Reliability – Stable operation in 24/7 environments; redundancy options mitigate unplanned downtime.
• Compatibility – Works with existing S800/S900 I/O and ABB networking practices; no disruptive rewiring in most cases.
• Cost‑effective upgrades – Reuse cabinets, wiring, and tools; shorten FAT/SAT time and reduce shutdown windows.
• Lifecycle support – Firmware alignment with 800xA roadmaps keeps systems supportable longer.
• Procurement confidence – Traceable part code (3BSE018161R2) and consistent quality screening.

A maintenance lead at a petrochem site told us the swap from an older PM8xx took half a shift, mainly because all their S800 I/O stayed untouched and Control Builder M projects migrated cleanly.

Installation & Maintenance

• Cabinet & environment – Install in a ventilated control cabinet, 0–55 °C ambient, with filtered air and stable 24 V DC supply.
• Grounding & EMC – Use proper PE bonding, segregate power and signal wiring, and maintain cable shields as per ABB guidelines.
• Networking – For redundant networks, configure RNRP (where applicable) and separate control vs service VLANs to avoid broadcast storms.
• Redundancy setup – If using redundant CPUs, pair units with SM801 and match firmware versions; verify switchover timing during SAT.
• Routine care – Back up projects via Control Builder M, check event logs periodically, and schedule firmware updates that match your 800xA version matrix.
• Timekeeping – Enable NTP on the control network; replace the RTC backup battery at the interval specified by ABB (typically during planned outages).
• Cleaning – Light dust removal with dry air; avoid solvents. Maintain clearance around module vents.

Quality & Certifications

• CE compliant; UL listing and RoHS conformity typically available for AC 800M family
• Manufactured under ISO 9001 quality systems by ABB
• Factory testing and serialization for traceability
• Warranty: 12 months (365 days) from shipment

Note: Specific port counts and redundancy accessories can vary by kit revision and firmware. If you’re replacing a running PM864A, share the current firmware and 800xA version—matching these upfront typically avoids surprise rework.
