It allows you to configure nominal voltage and current values ​​to protect the connected load from either low voltage or current, or high voltage and current. All information is displayed through a human-machine interface consisting of a 16x2 LCD screen with an I2C expander and a three-button arrangement that allows you to configure the system, modify nominal values, manually turn off the load, and restart the system. The main advantage of this system is the ability to modify and adapt it to the user's needs, as commercial motor guards are stand-alone systems, meaning they cannot send their information to a computer system and operate in isolation. We can, for example, send valuable data to a SCADA system, monitor remotely via the internet, graph variables in real time—the possibilities are endless. I hope this information is useful to you.
