3pcs XD-M131 DC 12V Photosensitive Resistor Module Light Control Switch Photosensitive Relay Module

Specification Product model XD M131Product Name photosensitive relay moduleOperating voltage 12VOutput mode one channel relayOverall size 52 x 31 x 31mmDescription 1 This product is mainly used for light detection brightness detection and control and other occasions through the potentiometer can be adjusted to detect brightness threshold With the relay it can do a variety of brightness detection switch you can control a variety of street lights to achieve automatic opening at night automatically extinguished during the day 2 Module uses 12V power supply with reverse connection protection function the reverse power supply will not damage the module 3 Normally open interface maximum load capacity 0V 125V 20A AC DC 0V 14V 20A the output module has three ports public terminal COM normally open CK and normally closed CB the three port is equivalent to a double control switch the relay coil is energized the public 0ften end with the beginning of Without electricity when the public end and the normally closed end of the pass COM end by loading the cathode of a power supply 0ften start power cathode 4 The sensitivity can be adjusted by potentiometer and the starting relay threshold is set by adjusting the potentiometer When the light is below the threshold the module relay is pulled in when the threshold is light the relay is disconnected 5 The module has been upgraded again has solved the critical b0unce phenomenon and improved the relay con
