Instructions for Use

1. Power Supply:

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

2. Control Signal:

   • Apply a control signal to the IN pin to activate the relay. The relay will switch when the control signal is high (3.3V to 5V).

3. Load Connection:

   • Connect the load to the COM (Common), NO (Normally Open), and NC (Normally Closed) terminals.
   • When the relay is activated, the COM terminal will connect to the NO terminal.
   • When the relay is deactivated, the COM terminal will connect to the NC terminal.

4. Indicator LED:

   • The built-in LED on the module will light up when the relay is activated, indicating that the control signal is being applied.

5. Mounting:

   • Secure the module to the PCB using the provided mounting holes.

6. Safety Precautions:

   • Ensure that the input voltage and control signals are within the specified range to avoid damage to the module.
   • Do not exceed the contact rating of the relay to prevent overheating or failure.
   • Handle the module with care to avoid physical damage, especially to the relay contacts and PCB traces.

7. Testing:

   • Before connecting the load, test the relay operation using a multimeter to ensure proper switching between the COM, NO, and NC terminals.

8. Troubleshooting:

   • If the relay does not switch, check the control signal and input voltage.
   • If the LED does not light up, verify the power supply and connections.

By following these instructions, you can effectively use the CM508-RI02 relay module in your projects.
