The traditional relay module often comes with complex wiring, which can be a challenge for beginners and students. Our simple switch module simplifies the wiring process when connecting traditional relays. The input end is equipped with an adapter that can work with most power sources, including battery boxes, DC power supplies, and power banks. While streamlining the wiring, it retains the NC and NO functions of relays. You can easily switch between normally open and normally closed modes by adjusting the toggle switch. DFRobot's latest easy relay module features a standard Gravity sensor interface and supports a wide voltage input range of 3.3V - 5.5V. This makes it a breeze to connect with main control boards like Arduino. It's perfect for a variety of control applications such as robot control, light control, smart home systems, and security setups. **Features**: 1. Operates at a working voltage of 3.3 - 5.0V, with wide voltage input, compatible with both 3.3V control boards and 5V main control boards. 2. Use the toggle switch to effortlessly switch between NC/NO modes, and an LED indicator shows the output status. 3. Comes with a DC2.1 input and output interface. With the included adapter, it's plug-and-play, suitable for most application scenarios. **Specifications**: 1. VIN operating voltage: 5V - 30V. 2. VIN operating current: 0A - 2.5A. 3. Logic power supply: 3.3 - 5.5V. 4. Logic signal: 3.3 - 5.5V. 5. Operating temperature: -55 ℃ - 150 ℃. 6. Switching characteristics: T (on) = 20us / T (off) = 50us. 7. Switching frequency: 1kHz. 8. Dimension: 37 * 27mm / 1.46 * 1.06in. **Documents**: Product wiki
Using this relay module is quite straightforward. First, connect the input end to your power source. Thanks to the adapter, you can use a battery box, DC power supply, or power bank. Then, connect the module to your main control board like Arduino using the standard Gravity sensor interface. You can switch between the normally open and normally closed modes by simply adjusting the toggle switch. The LED indicator will show you the output status. When using the module, make sure the input voltage and current are within the specified range (VIN operating voltage: 5V - 30V, VIN operating current: 0A - 2.5A). Also, keep the operating temperature between -55 ℃ and 150 ℃. To maintain the module, keep it clean and dry. Avoid exposing it to extreme conditions. If you encounter any issues, refer to the product wiki for more information.
