PM866K02 Central Controller

ABB PM866K02 Central Controller

Product Overview:
ABB PM866K02 is a high-performance redundant controller belonging to the ABB AC800M series. It is designed specifically for complex industrial automation systems, with high reliability, powerful processing capabilities, and flexible scalability, suitable for industrial scenarios that require extremely high system availability.

Main features and advantages
Redundancy design: Supports CPU redundancy, communication redundancy, and power redundancy. In the event of a main controller failure, it can seamlessly switch to a backup controller to ensure continuous system operation.
High performance processing capability: equipped with multi-core processors, with a main frequency of 133MHz, supporting multitasking parallel processing, and task cycles as low as 1ms, meeting high-speed control requirements.
Flexible communication and expansion: Built in 2 Ethernet interfaces (supporting redundant configuration), 2 RS232C interfaces, and Modbus expansion interfaces, compatible with multiple communication protocols (such as Modbus, PROFIBUS DP, OPC UA).
High reliability and safety: Industrial grade components are used, certified with IP20 protection level, and can operate stably in the temperature range of -20 ℃ to+60 ℃, adapting to harsh industrial environments.
Programming and configuration support: Use Control Builder M programming software, support IEC 61131-3 standard language (such as ladder diagrams, structured text), simplify complex control logic development.
