The PM861AK02 and PM861A01 are redundant processor units belonging to the PM861 family, which typically feature a 32-bit RISC(Reduced Instruction set computer) architecture and are equipped with 16 MB of RAM to support real-time multitasking. Redundant processors are designed to provide high reliability and fault tolerance in the system, and if one processor unit fails, another redundant processor unit immediately takes over, ensuring continuous operation of the system. This design enables the system to cope with hardware failures without interrupting business, thus improving the availability and stability of the system.

In addition, the PM861AK02 and PM861AK01 processor units also have error detection and error correction functions to detect and correct errors in the system to further improve system reliability, and they also support a variety of communication interfaces, such as interfaces. Ethernet interface and Rs 232c interface. To facilitate connection and communication with other devices or networks

Collectively, the W861AK02 and PW61AK0 redundant processor units are high-performance, highly reliable processor units for industrial control automation and test applications that require high availability and troubleshooting
