Descriptions
The module can be used for light detection and brightness detection.
It has a power indicator light (red) and a relay pull-in indicator light (blue).
It also has four M3 screw mounting holes, which greatly facilitates installation.
The board can adjust the light sensitivity through a potentiometer.
It has its own relay and can be used for various brightness detection control switches.
It can be used in, for example, street lights, which automatically turn on at night and turn off during the day, as well as other equipment that requires automation.
Board parameters
1. The module is powered by 5/12/24V (optional) and has anti-reverse connection function. Reverse connection of the power supply will not damage the module.
2. Normally open interface load capacity: AC 0V--125V/20A , DC 0V--14V/20A; the module output end has three ports: common terminal ( COM ), normally open ( CK ), and normally closed ( CB ).
3. The three ports are equivalent to a double-control switch. When the relay coil is energized, the common terminal and the normally open terminal are connected.
4. When there is no power, the common terminal and the normally closed terminal are connected.
5. 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.
