ABB PM864AK01 3BSE018161R1 AC 800M High-Performance Redundant CPU Module

Order Code: 3BSE018161R1

Product ID: PM864AK01

Brand: ABB

Product Family: AC 800M / System 800xA

Type: Central Processing Unit (CPU) / Controller Module

Product Overview

The ABB PM864AK01 (3BSE018161R1) is a high-performance central processing unit (CPU) module designed as the core brain for the ABB AC 800M controller series and the ABB Ability™ System 800xA Distributed Control System (DCS).

Engineered for mission-critical process automation, this processor unit provides the deterministic control and computational power required for large-scale industrial operations. Unlike standard PLCs, the PM864AK01 is built for high availability, featuring native support for 1:1 hardware redundancy. In a redundant pair configuration, two units operate in hot-standby mode, achieving bumpless failover with switchover times typically under 100ms to ensure uninterrupted production.

Key Features & SEO Keywords

1:1 Hardware Redundancy (Hot-Standby): Supports dedicated fiber-optic synchronization links. If the primary CPU fails, the backup takes over automatically with no process disruption.

High-Performance Processing: Powered by a 32-bit PowerPC architecture (PowerPC 604e or 750 series) running at frequencies up to 800 MHz or higher, handling complex logic and floating-point operations.

Large Memory Capacity: Equipped with substantial RAM (ranging from 32MB to 512MB depending on configuration) and Flash memory for extensive application code and data logging.

Extensive Communication Interfaces: Features multiple Ethernet ports (10/100/1000 Mbps) for control networks, RS-232C/RS-485 serial ports for Modbus RTU, and ModuleBus/CEX bus for I/O expansion.

System 800xA Integration: Natively compatible with ABB Control Builder M engineering software and the 800xA ecosystem, enabling vertical integration from field devices to MES/ERP.

Industrial Grade Reliability: Wide operating temperature range (-25°C to +70°C), robust EMC immunity, and IP20 protection for DIN rail installation.

Applications & Use Cases

The ABB PM864AK01 is the standard choice for industries requiring high availability and complex regulatory control:

Oil, Gas & Chemicals: Reactor control, FCC units, pipeline monitoring, and emergency shutdown (ESD) logic solving.

Power Generation: Unit DCS for coal, gas, or combined cycle power plants (Boiler-Turbine coordination).

Pharmaceuticals & Biotech: Batch process control (ISA S88) and critical environmental monitoring.

Metals & Mining: Rolling mill automation and material handling systems.

Water & Wastewater: Large-scale pumping station scheduling and treatment plant SCADA.

Why Choose the ABB PM864AK01?

If you are upgrading a legacy ABB system or building a new redundant control architecture, the PM864AK01 offers a balance of legacy compatibility and modern performance.

Installation & Redundancy Configuration

Hot-Swap Capability: The module supports online replacement in redundant configurations. If a fault occurs, the healthy CPU takes over, allowing the faulty unit to be replaced without shutting down the plant.

Wiring & Safety:

Base Plate: Must be mounted on a TP830 base.

Sync Cable: For redundancy, a dedicated fiber optic cable must connect the two CPU modules.

Battery: Ensure the backup battery (4943013-6) is installed to retain the real-time clock and retentive variables during power loss
