Mini relay 3v

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 is a common accessory module for electronic DIY fans. Equipped with a high current relay. Its max current can be up to 2A. Adopt a 3V power supply, which is enough to support micro:bit. Contact control, including a normally open contact and a normally closed contact. Convenient wire connection. Hardware Connection Connect the relay module to P1 on octopus:bit using a jumper cable.

Equipped with a high current relay. Its max current can be up to 2A. Adopt a 3V power supply, which is enough to support micro:bit. Contact control, including a normally open contact and a normally closed contact. Convenient wire connection. Hardware Connection Connect the relay module to P1 on octopus:bit using a jumper cable. Insert micro:bit into the edge slot of octopus:bit. Click to open Makecode, and write your code in the editor area. Set a high electric level to P1 port to make the normally open contact close and the normally closed contact open. Thus, we are able to control the connection of the contact switch through code.

It is essential to match the relay's ratings with the circuit's requirements to ensure optimal performance and longevity. Their use extends to situations requiring the control of motors, lights, and other high-current devices with precision and reliability.

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. Both ends of the coil are accessible from outside the relay via pins 1,2. These two pins are connected with the low-power signal to toggle the relay on and off. There are 3 more pins accessible from the outside.

Using a low-current signal, these relays are often used to control small motors and heaters. Prevent damage from voltage spikes, reduce signal interference, and amplify signal with these relays, which interface between your controller and components to isolate input and output circuits. Solder these relays directly to printed circuit boards using their solder pin terminals. With no moving parts, these solid state relays last longer, switch faster, and are quieter than mechanical relays. Unlike mechanical relays, these solid state relays have no moving parts, so they require less maintenance and last longer, switch faster, and are quieter. Often used for high-speed switching at low-current levels, these solid state relays have no moving parts, so they switch faster, last longer, and are quieter than mechanical switches. Also known as automotive relays, these relays can handle high starting inrush currents.
