Light dependent relay serves to switch-ON the lighting of streets, squares, shop windows, neon lamps etc, at twilight and to switch-OFF afore mentioned lighting at dawn.
On rail 35mm. 16A.
External answering machine probe placed at the site of access for natural light, which changes its intensity will be annexed to and result in switching on/off lights. The time of switching on lights can be set by the user by the potentiometer. Turnover in the "moon" - switch later, turnover in the "sun" - switch earlier. Light dependent relay posses system of delaying switch on/off lighting, which limiting the impact of disturbance (eg, lightning) to work.
In case of the length of the cable probe longer than 10m, should not be lead close to parallel power cable.
In the case of control measures light dependent relay tightly cover the entire appliance, such as a cardboard box or a dark, thick cloth. Cover only the "eye" the probe, such as the finger is not enough, because the intensity of sunlight is very strong and is passes to f by a plastic cover and the human body.
