The "IC T4L-LED-DK Module" has been designed to integrate low-voltage push-buttons of the LAURITZ KNUDSEN Denmark series into the digitalSTROM system. The module has integrated the dS features (yellow / gray) of the SW-TKM200 terminal. The extra-low voltage for the buttons connected via a ribbon cable is provided by the T4L-LED-DK module. Also on board is the power supply for the LEDs. This allows 4-way push-button elements to perform up to 16 functions in the dS. The low voltage side is galvanically isolated from the mains with> 2KV. The module is installed in the concealed / switch box. With dimensions of 41 x 41 mm and h = 27mm, it fits into the typical small standard cans in Denmark. Delivery is without button top.
