SD/S 2.16.1 ABB i-bus KNX Switch and Dim Actuator 2-Fold 16 A 1-10V MDRC Relay Module for Ballast Groups

The ABB i-bus KNX SD/S 2.16.1 is a two-fold switch and dim actuator in modular DIN-rail design (MDRC). Every channel pairs a potential-free 16 A relay with a 1-10 V control output, enabling lighting groups with electronic ballasts or 1-10 V LED drivers to be switched on/off and dimmed from 0 to 100% via ABB i-bus KNX or manual operation at the device.

Features include manual operation with visual status display and power supply directly from the KNX line, eliminating the need for separate power. Order code: 2CDG110079R0011, light grey, 0.18 kg.

• Bus system / protocol: KNX TP1 (twisted pair), S-Mode
• Outputs: 2 channels, each 1-10 V control output plus potential-free relay
• Rated operational voltage: 110...230 V AC, output voltage 230 V AC, 50/60 Hz
• Maximum switching current: 16 A per channel (AC1)
• Maximum control current DC: 100 mA
• Load types: electronic ballast 1-10 V, fluorescent lamps, universal
• Manual operation: yes, with status indication
• Power loss: 2.6 W total
• Enclosure / dimensions: IP20, 4 MW, 72 x 90 x 64.5 mm
• Certifications: CE, RoHS 2011/65/EU incl. amendment 2015/863, REACH (no SVHC above 0.1%), KNX certified

Ideal for office floors, meeting rooms, corridors, and hotel public areas where 1-10 V ballast luminaires are grouped per zone. The relay eliminates standby losses at zero dim level, and the 16 A rating handles the inrush current of larger lighting groups.
