The ABB i-bus KNX SD/S 8.16.1 is the highest-density switch and dim actuator of the i-bus 1-10 V family. Eight independent channels are packed into a single modular DIN-rail device (MDRC), with each channel featuring a potential-free 16 A relay and a 1-10 V control output for electronic ballasts.
Luminaires can be switched and dimmed over the bus or manually, without requiring a separate power supply. Manual operation with visual status indication is included. Order code: 2CDG110081R0011, light grey, 0.508 kg.
Well suited for open-plan office floors, conference centres, auditoriums, factory halls, and shopping malls with many individually addressable lighting zones. When combined with KNX light sensors, it supports daylight-dependent dimming, and with presence detectors, it links occupancy to illumination across eight groups from a single panel.
