The use of more and more LED lamps in commercial and residential properties is already in full swing. The resulting inrush currents and additional strong inductive loads challenge our high-quality relays again and again.

To meet the increasing demands, we have decided to replace the changeover relays in our devices with new relays with higher quality contact material. With the upgrade the relays can now handle currents up to 80A for 5ms compared to the previous 30A. You can find the improved relays in every IO-Server 3G and IO-Extension 3G from now on.

The universal actuator on the other hand does not need this upgrade, because the switch-on moment of the relays happens gently exactly at the zero crossing.

Have fun with the installation!
