Description: 1. The 8 Channel 5V Relay Board is an IoT component designed to operate eight electrically separated relay switches that can handle a maximum voltage of 5Volts and a current up to 30A. 2. Each channel comes with its own opto-isolated relay, ensuring the electrical isolation between the control circuit and the load circuit for safety and noise reduction. 3. The board offers a versatile application as it can be used to control various appliances, such as lights, pumps, motors, fans, and other electrical devices in IoT projects. 4. With an operating voltage range of 6V-12V DC, the relay module can be easily powered by batteries or a DC power adapter, providing flexibility for remote installations and portable projects. 5. The board comes with eight normally open (NO) relays that allow you to switch ON or OFF any connected device when a trigger event occurs in your IoT application. 6. To control the relay switches, the 8 Channel 5V Relay Board supports both digital input signals (suc
