XH-M131 module size: 53*31*19mm
The module can be used for light detection and brightness detection. It has a power indicator (red) and a relay pull-in indicator (blue), and has four M3 screw mounting holes, which greatly facilitates installation. The board can be adjusted by a potentiometer. Sensitivity, built-in relay, can be used as various brightness detection control switches, can be used in street lights, etc., automatically turn on at night, automatically turn off during the day, and other equipment that needs automation.
Board parameters
1. The module adopts 12V power supply and has the function of anti-reverse connection, and the reverse connection of the power supply will not damage the module,
2. The load capacity of the normally open interface: AC 0V--125V/20A, DC 0V--14V/20A, the module output has three ports common terminal (COM), normally open (CK), normally closed (CB), three The port is equivalent to a dual-control switch. When the relay coil is powered, the common terminal is connected to the normally open terminal, and when there is no power, the common terminal is connected to the normally closed terminal. 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,
