The LIM2® 4-Channel controller makes setting and calling up of colour of light or light level possible on keystrokes. 4 groups of lights with digital operating devices for a control voltage of 1-10 V (ex. fluorescent bulbs, low-voltage halogen, high volt halogen bulbs or LED applications) can be controlled, 4 light sequences pre-programmed can also be called up by keystrokes. Also a dynamic operational sequence of the setup light scenes is possible owing to selectable standing and blend over times. 4 different sequencing programs with 8 light scenes each are already programmed in the system. Further features are panic configuration, external switching entrance, variable time intervals. It is a comfortable system, whereby no prior knowledge is needed to operate it.
