The relays are 5 Volt making this compatible with Arduino and Raspberry Pi. Let us learn how to use one in our circuits based on the requirement of our project. separate hardware device used for remote device switching. The electromagnet requires a small voltage to get activated which we will give from the Arduino and once it is activated, it will pull the contact to make the high voltage circuit. It is equipped with high-current relays that work under AC250V 10A or DC30V 10A. If we want to control the device via relay through a software then we have to attach this device to its normally open terminal. Introducing the 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. Vcc=4,5V, Icc=69mA. The Arduino Relay module allows a wide range of microcontroller such as Arduino, AVR ,PIC, ARM with digital outputs to control larger loads and devices like AC or DC Motors, electromagnets, solenoids, and incandescent light bulbs. Each output pin of 2 relay module has its own functions. Relay pinout diagram is given in the figure shown below. When input voltage is applied across its coil, NC changes to NO and NO changes to NC. A relays Output Circuit is the portion of the relay that switches on the load and performs the same function as the mechanical contacts of electromechanical relays. These are brought out to screw-type terminal blocks for easy Internal structure of any electronic device leads to the better understanding about its working principle. I have also made another relay simulation in.

The input can be driven from 3.3V or 5V sources. Relay is an switch, which opens and closes the circuit electronically. JLCPCB – Prototype 10 PCBs for $2 (For Any Color) The small power relay has only one contacts, and the high power relay has two contacts for opening the switch. When the circuit of the relay senses the fault current, it energises the electromagnetic field which produces the temporary magnetic field. As I have told earlier, when we supply power the normally closed contact will changed its state to normally open contact and vice versa. variety of external devices. Product description The RPi Relay Board gives your Pi the ability to control high voltage/high current devices, easily makes normal home appliances become intelligent. The output is isolated via changeover relay contacts. 4 hannel 12V Relay Module 1. Well, if you feel the need of having a simple relay module, with just the basic components, you are at the right place. in Enterprise allows you  to open or close the two switches on the relay It can also be used to control lighting, electrical and other equipment. Relay internal structure is shown in the figure given below. I am a programmer since 2009 before that I just search things, make small projects and now I am sharing my knowledge through this platform. Relay can also be used in mobile robots to control their motion properly. When the relay gets energized, LED will be turned ON, as shown below. Before we proceed with the circuit to drive the relay we have to consider two important parameter of the relay. China’s Largest PCB Prototype Enterprise, 600,000+ Customers & 10,000+ Online Orders Daily To put it simply, it is an automatic switch to controlling a high-current circuit with a low-current signal. options are set you can choose when (or how often) you want the module houses two SPDT relays and one wide voltage range, optically isolated It is frequently used in automatic control circuit. Two relay board is given in the figure shown below. Does Icc needs more current for 4-channel? Controlling a relay module with the Arduino is as simple as controlling any other output as we’ll see later on. Working principle of array can be understand from the visuals given in the figure shown below. Relays are most commonly used switching device in electronics.
