LR/S 4.16.1 ABB i-bus KNX 4-Channel Light Controller DIN Rail 1-10V 16 A Daylight Harvesting Control Unit
The ABB i-bus KNX LR/S 4.16.1 is a four-channel lighting controller in modular DIN-rail format that handles four independently regulated lighting rows. It switches and regulates four groups of luminaires carrying electronic ballast gear and 1-10 V inputs. When paired with the LF/U 2.1 light sensor, the unit functions as a 4-fold constant lighting controller, comparing measured illuminance against configured setpoints and trimming each 1-10 V signal separately for precise daylight harvesting control.
- Each circuit receives its own sensor for enhanced accuracy in areas with varying brightness
- Ideal for large rooms where lighting conditions differ across the space
- Order code: 2CDG110088R0011
- Light grey finish, 0.33 kg weight
