6️⃣ How to Use

Setting up your 5v 8 Channel Relay Module | microsolution.com.pk takes just minutes. Follow these simple steps and start controlling your devices.

Step 1: Understand the Pins
The module has three input pins: VCC (5V power), GND (ground), and eight signal pins (IN1-IN8). On the output side, each relay has three terminals: COM (common), NO (normally open), and NC (normally closed) .

Step 2: Connect Power
Connect VCC to your Arduino's 5V pin and GND to ground. The module draws about 100mA when all relays are active . For heavy loads, connect an external power supply to JD-VCC .

Step 3: Wire Your Microcontroller
Connect IN1 to IN8 to your Arduino's digital pins. The module triggers on a LOW signal by default . When you set a pin to LOW, the corresponding relay activates.

Step 4: Connect Your Loads
Wire your devices to the relay outputs. Connect the live wire to COM and your load to NO. When the relay activates, the circuit completes and your device turns on .

Step 5: Write Your Code
Upload a simple sketch to test the relays. Use digitalWrite(pin, LOW) to activate and digitalWrite(pin, HIGH) to deactivate each relay.

Safety Tips:

• Never connect high-voltage wires while the module is powered

• Use appropriate wire gauges for your load current

• Keep the module away from flammable materials

• Use an external fuse for protection

• Double-check all connections before applying power

• Use the optocoupler isolation features properly

Maintenance Guidance:
Keep the module clean and free from dust. Periodically check screw terminals for tightness. Store in a dry location when not in use. The high-quality construction ensures years of reliable operation with proper care.
