Description
This product is mainly used for light detection, brightness detection and controlling, and can adjust the potentiometer to detect the threshold of brightness. The relay allows you to perform various brightness detection switches, control various street lights, open automatically at night and turn off automatically during the day
The module uses 12V power supply Reverse connection protection function, reverse power does not damage the module. The module has been upgraded again, serious phenomenon, improved relay control range, and can control 12V-220V
Normal open interface maximum load capacity: 0V-125V / 20A AC, DC 0V-14V / 20A; Output module has 3 ports: Public Terminal (COM), Normal Open (CK), Normal Close (CB), 3 ports correspond to a double control switch, the relay coil is excited and the public is often If there is no electricity, the path public end and normally closed end. The COM will end by loading the cathode of the power and often start the power cathode
The sensitivity can be adjusted with the potentiometer, and the start relay threshold is set by adjusting the potentiometer. When the light is below the threshold, the relay of the module is drawn and the threshold is lighted, the relay is disconnected
This module can be used for light detection, brightness detection. Power indicator light (red) and relay indicator (blue). 4 M3 screw mounting holes for convenient installation, the board can adjust the sensitivity. Potentiometer, with relay, can be used for street lights during the day, auto off and other automation equipment, etc
