LR/S 2.16.1 ABB i-bus KNX 2-Channel Light Controller DIN Rail 1-10V 16 A Constant Lighting Control Unit
LR/S 2.16.1 ABB i-bus KNX 2-Channel Light Controller DIN Rail 1-10V 16 A Constant Lighting Control Unit
PRODUCT SUMMARY
Constant illuminance regulation is what separates the ABB i-bus KNX LR/S 2.16.1 from an ordinary dimming actuator. This two-channel modular DIN-rail unit switches and regulates two groups of luminaires equipped with electronic ballast gear and 1-10 V inputs; once the light sensor LF/U 2.1 is wired to its sensor input, the device compares measured room brightness with the configured setpoint and continuously trims the 1-10 V signal, holding the illuminance steady as daylight changes. Up to two sensors may be linked to the controller, one per regulated circuit, for precise detection of the lighting conditions in each part of the room. Order code 2CDG110087R0011, light grey, 0.2 kg.
