Key Features:

1. Operating Voltage:

   • The module operates at a 5V DC input, making it compatible with most microcontrollers, such as Arduino and Raspberry Pi.

2. Max Current:

   • The relay can handle up to 20mA of trigger current, making it easy to control using low-power digital outputs.

3. Relay Type:

   • 1 Channel Relay, suitable for controlling one load, typically used in automation, home control systems, and microcontroller projects.

4. Load Capacity:

   • AC Load: Can control up to 250V 10A AC.
   • DC Load: Capable of switching 30V 10A DC.

5. Trigger Current:

   • Requires only 5mA of current to trigger the relay, making it efficient for microcontroller systems.

6. Trigger Type:

   • Low (Logic 0 / Ground): When the input is low or at ground level, the relay remains in the off state.
   • High (Logic 1 / Vcc): When the input is high (supply voltage, usually Vcc or Vdd), the relay will trigger, allowing current to flow through the load.

7. Safety Features:

   • Designed to meet international safety standards, with isolation grooves between the control area and the load area to prevent electrical interference and damage.

8. Convenient Terminals:

   • Features blue KF301 terminal blocks, which are more convenient for wiring and provide secure connections for both AC and DC circuits.

9. Indicator LEDs:

   • Includes power and relay operation indicators to show the status of the relay and power supply.

Applications:

• Home Automation:

  • Can be used to control household devices like lights, fans, and appliances remotely using a microcontroller.

• Arduino & Raspberry Pi Projects:

  • Ideal for use in various DIY electronics projects involving relays for switching high voltage AC/DC devices.

• Industrial Control:

  • Suitable for small automation or control systems, where low-power control signals are used to switch high-power loads.

• Home Appliances Control:

  • Useful for controlling electrical devices in home automation systems.

Advantages:

1. Low Trigger Current:
   • Requires very little current (5mA) to activate the relay, which is ideal for use with microcontrollers.
2. High Power Handling:
   • Can control devices with high voltage and current (up to 250V 10A AC or 30V 10A DC).
3. Easy Wiring:
   • Convenient terminal blocks make wiring quick and simple.
4. Safety:
   • Built to international safety standards, ensuring reliable and secure operation.
