This product is mainly used for swithcing the AC / DC load on off depending on the intensity of light. The level of brightness for switching can be set by using the potentiometer. This can be used to make automatic light on during night and off during the day. and various other similar applications.
Module uses 12V power supply with reverse connection protection function, the reverse power supply will not damage the module.
Normally open interface maximum load capacity: 0V-220V / 10A AC, DC 0V-14V / 20A the output module has three ports: Common terminal (COM), normally open (CK) and normally closed (CB), The three ports are equivalent to a double control switch, Before the relay coil is energised, the common is connected to the normally closed connection. Once the relay coil is energised using 12V power supply, the common terminal is connected to the normally open terminal to close the circuit and start the current flow in the load circuit.
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, and when the threshold is light, the relay is disconnected.
The module has been upgraded again, has solved the critical phenomenon, and improved the relay control range, 12V-220V can be controlled.
This product is mainly used for light detection & brightness detection
