12V Light Control Switch Photoresistor Relay Module Detection Sensor XH-M131

12V Light Control Switch Photoresistor Relay Module Detection Sensor XH-M131 Description

① Use of the photoresistor to induce light intensity with relay, direct control of the load
② Distribution bit sensitivity control, start relay threshold is set via potentiometer; When it is darker than this threshold, the module relay is switched on; when the brightness is above this threshold, the relay triggers;
③ 12V power supply input is designed for the relay board control valve to provide power to the sensor, making the product more stable and reliable;
④ Onboard optocoupler isolation drive relay, effective chip protection for more reliable product operation;
⑤ Four mounting bolt holes for easy installation
⑥ Material: Metal
⑦ Color: Blue
⑧ With leads, lead color is random
⑨ Module Usage Instructions:
⑩ 1. The photoresistor module is most sensitive to ambient light and is typically used to detect ambient light brightness.
⑪ 2. When the ambient light is darker than the set threshold, the relay is switched on; the common terminal and the normally open terminal are connected. connected; when the external ambient light is brighter than the set threshold, the relay is switched off, the common terminal and the normally closed terminal are connected;
3. The common terminal, the normally open terminal, and the normally closed terminal are three ports corresponding to a two-way switch; when the relay coil is energized, the common terminal and the normally open terminal conduct; Without current, the common terminal and the normally closed terminal conduct;
⑬ Supply voltage: 12VDC
⑭ Current: Greater than 100mA
⑮ Load: 250V 10A AC or 30V 10A DC (currents below this range can be used)
⑯ Size: 5.3cm 3cm
