Instructions:

1. Power Supply:

   • Connect the 5V DC power supply to the VCC and GND terminals of the relay module.

2. Control Signals:

   • Connect the control signals to the IN1 and IN2 terminals. A high signal (5V) will activate the corresponding relay, and a low signal (0V) will deactivate it.

3. Load Connection:

   • Connect the load to the COM, NO (Normally Open), and NC (Normally Closed) terminals of each relay.
   • For normally open operation, connect the load between COM and NO.
   • For normally closed operation, connect the load between COM and NC.

4. Installation:

   • Mount the relay module on a flat, stable surface.
   • Ensure proper ventilation to prevent overheating.

5. Safety Precautions:

   • Do not exceed the maximum ratings specified for the relay contacts.
   • Avoid operating the module in environments with high humidity or corrosive gases.
   • Ensure that the power supply is disconnected before making any connections or modifications.

6. Testing:

   • After installation, test the relays by applying control signals and verifying the operation of the load.

7. Maintenance:

   • Regularly inspect the relay module for signs of wear or damage.
   • Clean the module with a dry, soft cloth if necessary.
