What is a 5V relay
A 5V relay is an electronic device used as a switch to control the flow of current. It consists of an electromagnetic coil and a set of electrical contacts. When the electromagnetic coil is energized by a 5V DC power source, it generates a magnetic field that causes the contacts to move. These contacts can either connect or disconnect a circuit, thus controlling the flow of current.
5V Relays are designed to operate with a working voltage of 5V DC. They Find Wide Applications in Various Electronic Devices and Systems, Including Home Automation, A Utomotive Electronics, Industrial Automation, and IoT Projects. by Controlling The On/Off State of a 5V Relay , one can achieve control over lights, appliances, motors, and other devices.
Pin configuration for 5V relay
| Pin Number | Pin Name | Description |
|---|
| 1 | Coil End 1 | Used to trigger(On/Off) the Relay, Normally one end is connected to 5V and the other end to ground |
| 2 | Coil End 2 | Used to trigger(On/Off) the Relay, Normally one end is connected to 5V and the other end to ground |
| 3 | Common (COM) | Common is connected to one End of the Load that is to be controlled |
| 4 | Normally Close (NC) | The other end of the load is either connected to NO or NC. If connected to NC the load remains connected before trigger |
| 5 | Normally Open (NO) | The other end of the load is either connected to NO or NC. If connected to NO the load remains disconnected before trigger |
The role of the 5V relay
The main function of the 5V relay is to control the switching of the circuit. When the relay's control circuit is energized, the relay's electromagnet is activated, drawing the relay's contacts closed, energizing the circuit. When the control circuit is de-energized, the relay's electromagnet is deactivated, the contacts open and the circuit is de-energized
