ABB PM861A 3BSE018157R1 Processor unit

ABB PM861A 3BSE018157R1 processor unit is a high-performance industrial automation processor. It uses a high-performance processor to quickly and accurately handle various control algorithms and data processing tasks to meet the needs of industrial automation and control systems. .

The processor unit's backplane is designed with two RJ45 Ethernet ports (CN1, CN2), allowing it to be easily connected to the control network. In addition, there are two RJ45 serial ports (COM3, COM4), one of which (COM3) is an RS-232C port with modem control signals, and the other (COM4) is isolated and used to connect the configuration tool. This design enables the PM861A processor unit to achieve efficient and stable data transmission and communication in industrial automation systems.

At the same time, the processor unit also supports CPU redundancy, which is the key to achieving high availability. It ensures the reliable operation of the CPU, CEX bus, communication interface and S800I/0. In addition, the processor unit also has industrial-grade reliability, uses high-quality electronic components and manufacturing processes, and can work stably in harsh industrial environments.
