Description

ABB PM861AK02 AC800M series redundant controller

Hardware composition: The CPU board includes a microprocessor, 16M RAM memory, real-time clock, LED indicator light, INIT button and CompactFlash interface, providing data processing and control capabilities for the system. The base plate has two RJ45 Ethernet ports (CN1, CN2) and two RJ45 serial ports (COM3, COM4) for connecting to the control network. Among them, COM3 is the RS-232C port with a modem control signal, and COM4 is isolated and used for connecting configuration tools.
Redundancy function: Supports CPU redundant systems. By configuring dual cpus, it enhances the availability and reliability of the system, ensuring that when one CPU fails, the other can continue to operate, maintaining the normal operation of the system and reducing downtime.

Communication capability: It is equipped with multiple communication interfaces and can communicate and exchange data with other devices and systems through Ethernet ports and serial ports. It supports multiple communication protocols and can be conveniently integrated into different industrial networks.
Protection and security level: The module density ranges from 4 points to 32 points. Each module has an IP20 protection level and a security level of Class I and 2/ZONE 2, and can work stably in a certain industrial environment to ensure system security.
Functional features: It may also have on-site side diagnosis, electronic fuse or isolated input/output functions, etc. It can be used in conjunction with actuators such as stepper motors to receive signals from stepper drivers and control stepper motors to rotate at a fixed Angle in the set direction, achieving precise control.

Overall, the PM861AK02 is applicable to fields such as industrial automation and power system control. With its redundant design, powerful communication capabilities, and multiple functional features, it provides highly reliable and high-performance control solutions for industrial control systems
