This relay module consists of 4 relays. Each relay is connected to a current buffer so that you can connect them directly to a Microcontroller or Arduino.Using these relays you can easily control high power devices or appliances using arduino or microcontrollers, the relay is rated for 230V 10Amps. The Module has 5 LED’s, one for power and 4 for indicating relay signals.
Specifications:
- Rating: (250V AC or 30 V DC,10A )
- Input Control voltage: 5V DC
Connections to your Arduino (or microcontroller) side:
- VCC – supply voltage. 5V from my Arduino.
- IN1 – set to HIGH to set the relay to its “default” state, set to LOW to switch the relay to its alternate state
- IN2 – same as IN1, but controls the second relay on the board
- IN3 – same as IN1, but controls the second relay on the board
- IN4 – same as IN1, but controls the second relay on the board
- GND – ground
