Ref. IC-16-EXT

Twilight relay set with external SKS brightness sensor. Powered by 230V AC, it allows activating or deactivating the load (e.g., outdoor lighting) according to the ambient light level. The sensitivity threshold is adjustable and the device incorporates hysteresis to prevent false switching on and off due to false ambient light changes. Ideal for streetlights, illuminated signs, shop windows, or automatic security lighting.
