ABB DI820 module

The ABB DI820 is a module with a variety of functions and features.

First, the module is mainly used for voltage conversion, where the switching regulator uses inductance to temporarily store energy. The size of the inductor is usually large, so you need to arrange enough space for it when laying out the printed circuit board (PCB). This switching regulator quickly switches the current between two different paths to provide a stable voltage output.

Second, the DI820 module supports redundant installation of the AC800M central unit, which means that two central unit modules can be installed to work in parallel. One as the primary device and the other as the secondary device. If the main central unit module fails, the second module automatically takes over and performs the task, thus ensuring the continuity and stability of the system.

In addition, the module has network redundancy and is based on ABB's Residual Network Routing Protocol (RNRP). The protocol is designed to quickly detect network failures and immediately redirect traffic to another route, ensuring continuous transmission of data. This network redundancy requires two independent IP networks: the primary network and the secondary network.

In terms of safety, the DI820 module also has a Voltage Protection class (Up) to protect power system arresters and information system protectors from overvoltages.

In general, the ABB DI820 module provides reliable support for industrial automation and control systems with its stable voltage conversion, central unit redundancy and network redundancy.
