The ABB PM645B (3BSE010535R1) is a high - performance processor module serving as the core control unit of ABB Advant AC160 and Advant OCS controllers, engineered for medium - to - large - scale industrial process control scenarios demanding high reliability and real - time performance. It features a powerful CPU architecture, supporting redundant configuration to maximize system availability, and integrates multiple industrial communication interfaces for seamless connection with I/O modules, operator stations, and third - party devices. The module operates on 24VDC ±10% power supply, with a wide operating temperature range of - 25°C to +70°C and IP20 front protection, ensuring stable operation in harsh industrial environments with strong vibration and electromagnetic interference. It supports up to 200 control loops, making it suitable for process control applications in industries like petrochemicals, power generation, and water treatment, and is a key component for ensuring the stability and reliability of industrial automation systems.

The PM645B 3BSE010535R1 is equipped with a high - speed processor that can handle complex control algorithms, supporting up to 200 control loops to meet the requirements of medium - to - large - scale industrial processes. It supports redundant configuration, allowing two modules to work in hot standby mode. When a fault occurs in the main module, the standby module can switch over in less than 10ms, ensuring uninterrupted system operation. The module has a built - in memory backup battery to prevent data loss during power outages, and integrates hardware fault self - diagnosis function, which can monitor the status of CPU, memory, and communication interfaces in real time and report faults promptly. It also supports online programming and debugging, facilitating on - site maintenance and reducing downtime.
