ABB AC 800M Control Module

The ABB AC 800M control module is a module for industrial automation control systems with a variety of functions and features.

First, the module is equipped with a processor and RAM memory, as well as a real-time clock, LED indicator light, INIT button and secure digital interface. It can communicate via two RJ45 Ethernet ports (CN1, CN2) and one RJ45 serial port (COM4) for connecting to the control network. The COM4 port is isolated and used for configuration tools.

Second, the AC 800M control module supports CPU redundancy for higher availability (CPU, CEX bus, communication interface, and S800 I/O). The Communication Extension Bus (CEX bus) is used to extend the on-board communication port with a communication interface unit, while making it possible to use redundant communication interfaces on the CEX bus. Each PM891 is equipped with a unique Ethernet address that provides a hardware identity for the device.

In addition, the AC 800M control module also has some other features, such as microprocessor and RAM memory, real-time clock, LED indicator light and so on. At the same time, it also supports a variety of different configuration and extension methods, can meet the needs of different users.

In general, ABB AC 800M control module is a powerful and reliable industrial automation control system module, which has a wide range of application prospects.
