1 channel relay 5v optocoupler

🔹 1 Channel 5V Relay Module – Optocoupler Isolated

This 1-channel relay module uses optocoupler isolation to safely control high-voltage devices (lights, fans, motors) with low-voltage signals from Arduino, ESP32, or other microcontrollers.

✅ Specifications:

• Control Voltage: 5V DC

• Switching Capacity: 10A @ 250V AC / 10A @ 30V DC

• Trigger Modes: High or Low level (jumper selectable)

• Optocoupler Isolation: Yes (protects your microcontroller)

• LED Indicators: Power and relay status

📦 Connections:

• VCC → 5V

• GND → GND

• IN → Arduino/ESP32 control pin

📦 Applications:
✔️ Home automation (lights, fans)
✔️ Arduino/ESP32 projects
✔️ Motor and pump control
✔️ DIY electronics

⚠️ Note: Use external power for high-current loads.
