Description

Description: 12V Light Controlled Switch Photoresistor Relay Module This module can be used for light detection, brightness detection, with power indicator (red) and relay pull-in indicator (blue). With four M3 screw mounting holes, which greatly facilitates installation. The board can adjust the sensitivity of the light through the potentiometer. It has its own relay and can be used as a variety of brightness detection control switches. It can be used in street lights, etc., automatically turn on at night, and automatically turn off during the day, as well as other equipment that needs to be automated. 1. The module adopts 12V power supply and has the function of anti-reverse connection. damaged modules; 2. Load capacity of normally open interface: AC: 0V--125V/20A, DC: 0V--14V/20A; The output of the module has three ports common terminal (COM), normally open (CK), normally closed (CB), The three ports are equivalent to a dual-control switch. When the relay coil is powered, the common terminal and the normally open terminal are connected. When there is no power, the common terminal and the normally closed terminal are connected. The COM terminal is generally connected to the negative pole of the power supply through the load, and the normally open terminal is connected to the positive pole of the power supply. 3. The sensitivity can be adjusted by the potentiometer. By adjusting the potentiometer, the threshold value of the start relay can be set. When the light is dark at this threshold value, the module relay is pulled in, and when it is bright at this threshold value, the relay is disconnected. Product Usage: This product is mainly used for light detection, brightness detection and control, etc. The detection brightness threshold can be adjusted through the potentiometer. With its own relay, it can be used as a variety of brightness detection switches, and can control various street lights to automatically turn on at night and automatically turn off during the day. Light threshold can be adjusted by the potentiometer. Supply voltage: 12V LED indicators: Red - Power on, Blue - Relay energised Three output terminals: normally open (NO), normally closed (NC) & common (COM). Photoresistor cable length approx: 30cm Size: 30mm X 53mm X17mm (L X W X H) Package List: 3/4/5pcs * 12V Light Controlled Switch Photoresistor Relay Module note: Please allow 1-2cm errors due to manual measurement.
