SD/S 8.16.1 ABB i-bus KNX Switch and Dim Actuator 8-Fold 16 A 1-10V MDRC High-Density Office Module

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.
