Description
🔹 Product Introduction
The ABB PM861AK01, part number 3BSE018157R1, is a processor unit for the ABB AC 800M programmable controller family. It is designed for industrial process automation and distributed control applications, supporting execution of control logic, communication with compatible system components, and coordination of connected I/O modules.
The PM861A controller supports redundant and non-redundant configurations depending on the system design and installed hardware. It is used in applications such as power generation, manufacturing, chemical processing, and other continuous-process industries. Configuration and replacement work should follow the applicable ABB engineering documentation.
Before installation, verify the CPU hardware revision, firmware compatibility, controller configuration, communication interfaces, and installed Control Builder software version. Confirm the complete kit contents because the PM861AK01 designation may refer to a package that differs from the PM861A processor alone.
