SD/S 4.16.1 ABB i-bus KNX Switch and Dim Actuator 4-Fold 16 A 1-10V MDRC Lighting Unit with Free Relays
The SD/S 4.16.1 from the ABB i-bus KNX range is a four-fold switch and dim actuator designed for modular DIN-rail mounting (MDRC). This advanced lighting control solution features four independent channels, each combining a potential-free relay with a 1-10 V interface.
Each channel can individually switch and dim separate groups of luminaires with electronic ballasts, providing flexible control either through the KNX bus system or via manual operation at the device. The actuator operates directly from the KNX line, eliminating the need for external power units.
