Instructions

1. Power Supply:

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

2. Control Signals:

   • Connect the control signals from your microcontroller or logic circuit to the IN1, IN2, IN3, and IN4 terminals.
   • Apply a high signal (TTL level, typically 5V) to the input terminal to activate the corresponding relay channel.

3. Load Connection:

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

4. Grounding:

   • Ensure that the ground of the control circuit and the power supply are connected to the same ground to avoid potential issues.

5. Mounting:

   • Mount the module securely in a well-ventilated area to ensure proper heat dissipation.
   • Avoid placing the module near sources of high temperature or humidity.

6. Testing:

   • Before connecting the load, test the relays with a simple LED or buzzer to ensure they are functioning correctly.
   • Use a multimeter to verify the continuity of the relay contacts when activated and deactivated.

7. Safety:

   • Do not exceed the maximum contact rating of the relays.
   • Ensure that the load is disconnected before applying power to the module.
   • Follow all safety guidelines and regulations for handling electrical components.

8. Troubleshooting:

   • If a relay does not activate, check the control signal and power supply connections.
   • If the relay activates but the load does not operate, check the load connections and the load itself.
   • If the module overheats, ensure proper ventilation and reduce the load current if necessary.
