ABB PM864AK01 is a high-performance processor module for AC800M controller and 800xA DCS platform. It supports redundancy operation, executes real-time control logic, and manages I/O signals and network communication for medium and large process control systems.

PM refers to processor module. 864 indicates the performance grade. A stands for hardware revision. K means the module is capable of redundancy configuration. 01 is the code for product variant.

This module adopts a 32-bit PowerPC processor with a clock speed of 533 MHz. It is equipped with 512 MB battery-backed SDRAM and 256 MB Flash memory. It can support up to 4096 I/O points. The execution time for each Boolean instruction is 0.15 µs. The rated operating voltage is 24 V DC with an operating range from 19.2 V DC to 30 V DC. The typical power consumption is 6.9 W and the maximum power consumption is 11.4 W. The operating temperature ranges from 5 °C to 55 °C. The storage temperature ranges from -40 °C to 70 °C. The relative humidity is 5 % to 95 % without condensation. The protection class is IP20 and the overall weight is about 1.2 kg.

It has two 10/100 Mbps Ethernet ports which support PROFINET, Modbus TCP and OPC UA protocols. It is fitted with one RS-232 port and one isolated RS-485 port. A dedicated interface is provided for redundancy synchronization. It is compatible with CEX-Bus, ModuleBus and RCU-Link system buses. A CompactFlash slot is reserved for program and data storage.

It runs IEC 61131-3 compliant control programs in real time. It realizes 1:1 hot standby redundancy and bumpless switchover. It completes high-speed I/O scanning and closed-loop control tasks. It integrates diagnosis and fault recording functions for routine maintenance. It enables data exchange with upper management systems via industrial network. It supports a variety of professional control function libraries for different industrial demands.

It is widely applied in process industries including power, chemical, oil and gas, pulp and paper. It is suitable for control systems that require high operational availability. It can be used for medium voltage drive control and overall plant automation. It is also applicable to the renovation and upgrade of legacy control systems.

Mount the module on the DIN rail of AC800M rack and ensure reliable grounding and sufficient ventilation. Use shielded cables for communication wiring and comply with EMC requirements. Check the backup battery regularly to avoid data loss during power interruption. Inspect status indicators and system logs periodically, and update firmware with professional configuration software. Connect the dedicated synchronization link when configuring two modules for redundancy. Take anti-static protection measures during installation and replacement to prevent component damage.
