Mini relay 3v

This is a common accessory module for electronic DIY fans. Equipped with a high current relay. Its max current can be up to 2A.

A 3V DC relay is a fundamental component in modern electrical systems, designed to control a high-power circuit using a low-power signal. This electromechanical switch operates on a 3-volt direct current DC and is widely utilized in various applications due to its ability to manage large currents after being triggered by a small voltage. The versatility of the 3 volt DC relay is evident in its diverse types, each tailored for specific applications. From single-pole single-throw SPST to more complex multi-pole double-throw MPDT configurations, these relays are integral in automotive electronics, home appliances, and power systems. Their use extends to situations requiring the control of motors, lights, and other high-current devices with precision and reliability. The construction of a 3V DC relay involves various materials, including copper coils, magnetic cores, and contact materials like silver alloy, which are selected for their conductivity and durability. Features such as coil resistance, contact current rating, and mechanical lifespan are critical specifications that define a relay's capability.

This article shows how to control mains voltage with the Arduino using a relay module. We make a brief introduction to the relay module and build a simple project example with the Arduino. By the end of this tutorial, you should be able to control any electronics appliances with your Arduino using a relay module. A relay is an electrically operated switch that can be turned on or off, letting the current go through or not, and can be controlled with low voltages, like the 5V provided by the Arduino pins. This relay module has two channels those blue cubes. There are other models with one, four and eight channels.

Working with relays in combination with higher AC voltages is dangerous and can cause damage to yourself or a fire. So, it is intended for people with experienced and knowledgeable about higher AC voltages. For permanent use, make sure to use a relay for housing technology and not microelectronic. A relay is an electrical switch which toggles on and off by energizing a coil. The coil is made of wire wrapped around an iron core to provide a low reluctance for the magnetic flux.
