Instructions for Use

1. Power Supply:

   • Ensure the input voltage is within the specified range (12V - 24V DC) to avoid damage to the relay module.

2. Installation:

   • Mount the relay module on a suitable surface using the provided mounting holes or clips.
   • Ensure proper ventilation to prevent overheating.

3. Wiring:

   • Connect the positive terminal of the power supply to the VCC pin.
   • Connect the negative terminal of the power supply to the GND pin.
   • Connect the control signal to the IN pin.
   • Connect the load to the COM and NO (Normally Open) or NC (Normally Closed) terminals as required.

4. Operation:

   • When a control signal is applied to the IN pin, the relay will switch the contacts from the NC position to the NO position.
   • When the control signal is removed, the relay will return to its default state (NC position).

5. Maintenance:

   • Regularly inspect the relay for signs of wear or damage.
   • Clean the relay with a soft, dry cloth. Avoid using abrasive materials or solvents.

6. Safety:

   • Do not exceed the maximum switching capacity of the relay to prevent electrical hazards.
   • Ensure all connections are secure and properly insulated to avoid short circuits.
   • Follow all local electrical codes and regulations when installing and using the relay.
