ABB PM861AK02 3BSE018160R1 Redundant processor unit

ABB PM861AK02 3BSE018160R1 Redundant processor unit is a high performance, high reliability central processing unit (CPU), widely used in industrial automation and control systems. Here are some of the key features and functions of this redundant processor unit:

Redundant design: The processor unit is redundant and contains two PM861A processors and two TP830 docks for higher system availability and fault tolerance. When the main processor fails, the standby processor can immediately take over the work, thus ensuring the continuous operation of the system.

Connection ports: The base plate of the processor unit has two RJ45 Ethernet ports (CN1, CN2) and two RJ45 serial ports (COM3, COM4) for connecting to the control network. One of the serial ports (COM3) is the RS-232C port with the modem control signal, while the other port (COM4) is isolated and used to connect to the configuration tool.

Real-time clock and storage capabilities: The processor unit also includes a real-time clock, RAM memory, LED indicators, INIT buttons, and CompactFlash interfaces for a variety of control and monitoring needs.

High reliability: Through the redundant configuration and backup mechanism, the processor unit can effectively reduce the risk of service interruption or quality degradation caused by partial system faults, and improve the overall system performance and reliability.

In summary, the ABB PM861AK02 3BSE018160R1 redundant processor unit is a powerful and reliable central processing unit suitable for a wide range of industrial automation and control systems.
