Product Overview
When process uptime is non-negotiable, the ABB PM860AK01 Industrial Automation Module delivers the processing power and connectivity your control system demands. Built on the proven MPC860 processor running at 48 MHz, this CPU board integrates microprocessor, RAM memory, real-time clock, LED indicators, INIT push button, and a CompactFlash interface—all in a compact, DIN-rail mountable package.
The base plate of the ABB PM860AK01 provides two RJ45 Ethernet ports (CN1, CN2) for Control Network connection and two RJ45 serial ports (COM3, COM4). COM3 is an RS-232C port with modem control signals; COM4 is isolated for configuration tool connection. A unique Ethernet address on the TP830 base plate gives every CPU a hardware identity, simplifying asset tracking and network management.

Industry Applications
The ABB PM860AK01 excels in continuous process industries such as oil & gas, power, and chemical plants, where reliable control is critical. Its fast cycle times (down to 1 ms) and 32 tasks per controller make it ideal for high-speed discrete and batch control.
In a typical application, the PM860AK01 serves as the main controller for a distributed control system (DCS), managing multiple I/O clusters (up to 96 I/O modules on Modulebus) and communicating with supervisory systems via Ethernet. Its redundancy support (optional) and redundant power supply status input enhance system availability.
Installation & Setup
Mount the ABB PM860AK01 on a standard DIN rail using the unique slide & lock mechanism. Ensure the base plate (TP830) is correctly attached and the Ethernet address label is visible for identification. Connect the Control Network to CN1 and CN2 using RJ45 cables. For configuration, connect a service tool to COM4 (isolated RS-232C). Power the module with 24 V DC (19.2-30 V DC) and verify the power consumption does not exceed 300 mA typical. The module is IP20 rated, so install it in a clean, dry environment or within an appropriate cabinet.
Maintenance & Reliability
Routine maintenance is minimal. Periodically inspect the DIN rail mounting and ensure the ventilation slots are free from dust. Check the built-in lithium backup battery (3.6 V) annually and replace it if the real-time clock drifts. The module's robust design, with 100 ppm clock stability and G3 corrosion protection, ensures long service life in harsh environments.
Selection Guide
When purchasing the ABB PM860AK01, verify the article number 3BSE066495R1 to ensure you receive the correct revision. Confirm your system's compatibility with ABB 800xA (version 5.1 FP4 or later) and check the required number of I/O modules (max 96). For redundant configurations, note that this specific unit does not support redundancy; choose a redundant-capable model if needed.
