XH-M131 Photoresistor module brightness automatic control light switch light control relay 24V

Can be used as light detection, brightness detection, with a power indicator (red) and relay suction indicator (blue), and with four M3 screw mounting holes, greatly convenient installation, the board can adjust the sensitivity through the potentiometer, comes with a relay, can do a variety of brightness detection control switch, can be used in such as street lights, etc., automatic opening at night, Automatic extinguishing during the day, and other equipment that needs automation.
Module parameters:
1, the module adopts 12V power supply, with anti-reverse connection function, reverse connection power will not damage the module;
2,
normally open interface load capacity: AC 0V--125V/20A, DC 0V--14V/20A; The output end of the module has three ports, common end (COM), normally open (CK) normally closed (CB), the three ports are equivalent to a double control switch, when the relay coil is powered, the public end and the normal start, no power, the public end and the normally closed end; COM terminal is generally connected to the negative terminal of the power supply through the load, and usually starts to connect to the positive terminal of the power supply
