[Click the image to enlarge it]Relay Pin ConfigurationPin NumberPin NameDescription1Coil End 1Used to trigger(On/Off) the Relay, Normally one end is connected to 5V and the other end to ground2Coil End 2Used to trigger(On/Off) the Relay, Normally one end is connected to 5V and the other end to ground3Common (COM)Common is connected to one End of the Load that is to be controlled4Normally Close (NC)The other end of the load is either connected to NO or NC.. You can also notice a diode connected across the coil of the relay, this diode is called the Fly backDiode.. As shown one end of the load can be connected to the Common pin and the other end is either connected to NO or NC.. Once is the Trigger Voltage, this is the voltage required to turn on the relay that is to change the contact from Common->NC to Common->NO.. In order to know how to connect a DPDT relay, you must know what each pin terminal represents and how the relay works. Click

How to use a RelayRelays are most commonly used switching device in electronics Let us learn how to use one in our circuits based on the requirement of our project.. If connected to NC the load remains connected before trigger5Normally Open (NO)The other end of the load is either connected to NO or NC.. Our relay here has 5V trigger voltage, but you can also find relays of values 3V, 6V and even 12V so select one based on the available voltage in your project..

Make sure the load you are using falls into this range The above circuit shows a bare-minimum concept for a relay to operate.. Since the relay has 5V trigger voltage we have used a 5V DC supply to one end of the coil and the other end to ground through a switch.. 2D model of the Relay$begingroup$I have the relay you see here:How do I read that diagram - or specifically, which contact is the common, normally open, and normally closed contact?TheStoryCoderTheStoryCoder$endgroup$ 2 Answers $begingroup$Left terminal: Normally OpenCenter terminal: CommonRight terminal: Normally ClosedConfirm by measurement.. This switch can be anything from a small transistor to a microcontroller or a microprocessor which can perform switching operating.. If connected to NO the load remains disconnected before triggerFeatures of 5-Pin 5V RelayTrigger Voltage (Voltage across coil) : 5V DCTrigger Current (Nominal current) : 70mAMaximum AC load current: 10A @ 250/125V ACMaximum DC load current: 10A @ 30/28V DCCompact 5-pin configuration with plastic mouldingOperating time: 10msec Release time: 5msecMaximum switching: 300 operating/minute (mechanically)Equivalent Relays3V Relay, 12V Relay, 1-channel Relay module, 4-channel Relay Module.

Before we proceed with the circuit to drive the relay we have to consider two important parameter of the relay. ae05505a44 Click

If connected to NO the load remains disconnected before trigger and if connected to NC the load remains connected before trigger.. How to Connect a DPDT Relay in a Circuit In this article, we go over how to connect a Double Pole Double Throw (DPDT) relay in a circuit.. The other parameter is your Load Voltage & Current, this is the amount of voltage or current that the NC,NO or Common terminal of the relay could withstand, in our case for DC it is maximum of 30V and 10A.. Applications of RelayCommonly used in switching circuits For Home Automation projects to switch AC loadsTo Control (On/Off) Heavy loads at a pre-determined time/conditionUsed in safety circuits to disconnect the load from supply in event of failureUsed in Automobiles electronics for controlling indicators glass motors etc. HERE
