Instructions

1. Power Supply:

   • Connect the input voltage (3.3V to 5V DC) to the VCC and GND pins.

2. Control Signal:

   • Apply a control signal to the IN pin to switch the relay on or off.
   • A high signal (3.3V to 5V) will activate the relay, and a low signal (0V) will deactivate it.

3. Load Connection:

   • Connect the load between the COM (Common) and NO (Normally Open) or NC (Normally Closed) terminals.
   • For normally open operation, connect the load between COM and NO.
   • For normally closed operation, connect the load between COM and NC.

4. Safety Precautions:

   • Ensure that the load current does not exceed the contact rating of the relay.
   • Avoid connecting the relay to high-voltage circuits without proper insulation and safety measures.
   • Do not operate the relay in environments with excessive dust, moisture, or corrosive gases.

5. Mounting:

   • Mount the relay module on a PCB or a suitable surface using the provided mounting holes.
   • Ensure that the module is securely fastened to prevent mechanical stress on the connections.

6. Testing:

   • Before connecting the load, test the relay by applying a control signal and verifying the switching action using a multimeter or a continuity tester.

7. Troubleshooting:

   • If the relay does not switch, check the power supply, control signal, and connections.
   • If the relay clicks but does not switch the load, check the load and the relay contacts for any issues.
