A relay is a type of switch that can be controlled with an electrical signal. It is a way to open or close a circuit in this case via a signal from the connected microcontroller. The relay isolates the circuit on the device you want to control from the device that's controlling it.
This relay can be logically controlled with a 12V device. It is equipped with a optocoupler to safely separate high-voltage and low-voltage components.
- Triggering current: 5mA
- Working voltage: 12V
- Size: 50mm*26mm*18.5mm ( L*W*H )
- Fault-tolerant design , even if the control line is broken , the relay will not operate
- Interface design humane, all interfaces can be connected directly via terminal wiring leads, very convenient
- The module can be set to high or low triggered by jumper
- Sprinkler systems
- Turn on/off systems
- Door opener systems
