The SC expansion module makes it possible to save and control light scenes via the modularDIM system. With modularDIM BASIC, the light is set to the required levels on the 3 DSI channels. A scene is then easily saved by pressing and holding, for example, pushbutton 1 of 4 on the modularDIM SC. Up to 4 scenes can be saved. modularDIM SC has active inputs with 24 V (SELV), which makes it easy to connect conventional momentary pushbuttons.
