12V XH-M131 Light Control Switch Relay Photoresistor Module
Four M3 screw mounting holes on this module make installation much easier. It features a built-in relay and potentiometer sensitivity, and it may be used to detect light and brightness. Additionally, it may be used to manage brightness sensing in a number of ways, including automatically opening at night and extinguishing lights during the day. It is also possible to automate other pieces of equipment that need it.
Board specifications
Reversing the power source won't harm the module because of its anti-reverse feature;
Three ports on the module's output are common (COM), normally open (CK), and normally closed (CB). These three ports are comparable to a dual control switch, and the relay coil is powered by electricity. The COM terminal is typically connected to the power source via the negative, and the common side and normally closed side conduction are normally open when there is no power.
The module relay pulls, lights this threshold, and turns the relay off when the light is hidden inside the start relay threshold that is adjusted by altering the potentiometer to change the sensitivity.
Specification:
- A potentiometer can be used to change the light threshold and set the relay start.
- 12V DC input
- Capacity to load: 10A at 250V AC or 30V DC
- The power on is shown by a red LED.
- BLUE LED ACTIVE: The relay is operational
- There are three ports on the module output terminal.
- Pinouts for Relays
- Open normally (NO)
- Terminal common (COM)
- Closed normally (NC)
- Dimensions: 30 x 53 mm
