2 Channel 5V Relay Module with Optocoupler
This is a LOW-Level 5V 2-channel relay interface board, and each channel needs a 15-20mA driver current. It can be used to control various appliances and equipment with large current. It is equipped with high-current relays that work under AC250V 10A or DC30V 10A. It has a standard interface that can be controlled directly by the microcontroller.
The pins are marked on the PCB:
- GND – Connect 0V to this pin.
- IN1 – Controls relay 1, active Low Relay will turn on when this input goes below about 2.0V
- IN2 – Controls relay 2, active Low Relay will turn on when this input goes below about 2.0V
- VCC – Connect 5V to this pin. Is used to power the optocouplers
