6️⃣ How to Use

Setup Instructions

Using the 2-Channel Relay Module with Optocoupler Isolation is straightforward. Start by connecting the VCC pin to your 5V power supply. Connect GND to the ground . Then connect the IN1 pin to a digital output pin on your microcontroller. Connect IN2 to another digital output pin .

Next, connect your load device to the relay terminals. Connect the active wire to the COM terminal. Connect your device to the NO terminal for normally open operation. Alternatively, connect it to NC for normally closed operation . Ensure all connections are tight and secure.

Write your microcontroller code to control the relay. Send a HIGH signal to activate the relay in high-level trigger mode. Send a LOW signal to deactivate it. The status LED will light up when the relay activates .

Safety Tips

Always disconnect power before making wiring changes. Do not exceed the relay's 10A current rating. Use appropriate gauge wire for your load current. Keep high-voltage wiring away from low-voltage control circuits. Ensure your power supply can handle the load current. Never touch the output terminals while power is applied.

Maintenance Guidance

Keep the module clean and free from dust. Check screw terminal connections periodically for tightness. Replace the module if the relay contacts show signs of wear. Store in a dry place when not in use. Avoid exposing the module to moisture or extreme temperatures.
