Protection of HMI Panels Against Overvoltages

Protection of HMI Panels from Overvoltages; One of the most important components of our automation and production systems is the HMI, i.e., Human Machine Interface. Thanks to HMI Panels, process operations can be carried out in a much more understandable and easier way. HMI (Human Machine Interface) provides communication between the automation system and the user. The HMI panel transmits the commands received from the user to the automation system and displays the data received from the automation system on its screen. HMI Panels can be considered as powerful microcomputers hosting an operating system. Monitoring, managing, diagnosing, and controlling take place thanks to HMI panels.

Why Should HMI Panels Be Protected from Overvoltages?

HMI Panels are mandatory for the uninterrupted continuation of automation and production. Often in facilities, it can be difficult to restart the automation system because the software inside cannot be accessed in case of HMI Panel malfunctions. Preparing SCADA or HMI diagrams on existing automation systems is very troublesome and time-consuming. Therefore, it is necessary to protect our HMI systems without damage.

Since HMI Panels operate on an electronic system, they are devices with low Up protection levels that are easily affected by sudden overvoltage impulses. Therefore, it is not possible to protect these devices without cascaded protection. Our protection logic is to minimize the impulses that may come to the system by protecting from the main panel to the final HMI Panel power supply.

• Main Panel: Type 1+2+3 LV Surge Arrester (Parallel to the panel, to be connected with 16 mm cable)
• Sub-Distribution Panel: Type 2+3 LV Surge Arrester (Parallel to the panel, to be connected with 6mm cable)
• HMI Panel Power Supply Protection Type 3 Surge Arrester Generally used as 24 V DC

HMI Panels are systems that are developing further and becoming more sensitive with Industry 4.0. It is obvious that these systems will be used much more in production and processes in the future. As Yılkomer, it is the protection of your HMI Panels and panels, which are an important part of automation systems, with LV surge arresters.
