The module can be used for light detection and brightness detection. It has a power indicator (red) and a relay pull indicator (blue), and has four M3 screw mounting holes, which greatly facilitates the installation. The board can be adjusted by the potentiometer. Sensitivity, self-contained relay, can be used as a variety of brightness detection control switches, such as street lights, etc., automatically turn on at night, automatically turn off during the day, and other equipment that needs automation.
1. The module adopts 12V power supply and has the function of anti-reverse connection. Reverse connection of the power supply will not damage the module;
2. The maximum load capacity of the normally open interface: AC 0V-125V/20A , DC 0V–14V/20A; the output of the module has three common ports ( COM ), normally open ( CK ), normally closed ( CB ), three Each port is equivalent to a dual control switch. When the relay coil is energized, 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
Supply voltage: 12VDC
