The 'IC T4L-LED module' is designed for integrating low-voltage buttons into the digitalSTROM system. The button series (e.g. 4-way button from the JUNG 4224 TSM series) is used in the A, CD and LS switch ranges. Both the button voltage and the external LED supply are provided by the T4L-LED. The module has the dS functional features of the SW-TKM 200 terminal. This means that 4-way button elements can perform up to 16 functions in the dS system. The line voltage for the connected buttons is provided by the T4L-LED module with 13 V DC and a current of approx. 11 mA. For service and commissioning, each line is equipped with an internal LED (circuit board) that lights up when the button is closed. There are 2 connection variants available for the external LEDs on the JUNG button. The low voltage side is galvanically separated from the mains with >2KV. The module is installed in the flush-mounted/switch box. With its dimensions of d=54mm and h=26mm, it also fits in standard boxes. The integrated dS Joker function (black) enables assignment in the dS system for yellow (light) as well as gray (shadow), for example. You can choose between 3 light intensities (100% 50% 33%).
