LR/S 4.16.1 ABB i-bus KNX Light Controller 4-Fold 1-10V 16 A MDRC Daylight Harvesting Office Module
The ABB i-bus KNX LR/S 4.16.1 is a four-fold light controller in modular DIN-rail design (MDRC) for switching and dimming four independent groups of luminaires with electronic ballasts and 1-10 V control inputs. In combination with the light sensor LF/U 2.1 it operates as a 4-fold light controller for constant light control.
