Relay plug has a electromagnetic relay with driver circuit which enables the user to control High power circuit from a low power circuit. Both high power AC loads as well as DC loads can easily be controlled with this plug.This plug also has an LED associated with relay which represents the status of the relay i.e., when the relay is activated LED turns ON. Note: Please keep in mind that this plug is really meant for someone with experience and good knowledge of electricity. There are two types of relay plugs namely A-type and B-type. The only difference between these types of plugs is that A-type relay plugs have the relay terminals as an output port whereas B-type relay plugs have two separate output ports for high power supply and the high power load.
The Relay plug contains all the necessary circuit you need to get your high-power load under control. The relay driver circuit has a transistor equipped with free wheeling diode to protect the transistor from back EMF. Hence relay can be easily controlled by 5V logic from any digital circuit and an LED indicator tells you when the relay is activated. The relay plug has Screw terminal connectors on one side of the plug which makes it easy to incorporate into many projects.. Relay plug is a digital output device. It has a interfacing port with three pins named as G, V & D. Here G represents Ground , V represents VCC and D represents Data pin through which relay can be controlled. To activate the relay Plug the corresponding data pin on the controller board to which the relay plug data pin is connected must be made HIGH and to deactivate the relay plug, the data pin must be set to LOW. Every relay has five terminals out of which three terminals are named as C, NO and NC. The remaining two terminals are from the coil which generates the magnetic field when current is supplied to it. ● Common contact ( C ): This pin gets connected to NO pin when the relay is activated and it gets connected to NC pin when the relay is deactivated. ● Normally Open Contact (NO): NO contact is also called ‘make contact’. It closes the circuit when the relay is activated. It disconnects the circuit when the relay is inactive. ● Normally Closed Contact (NC): NC contact is also known as ‘break contact’. When the relay is activated, the circuit disconnects. When the relay is deactivated, the circuit connects. Elint Labz (www.elintlabz.in)

Use either of the supported cables to connect this relay plug to the controller board. If 4-3A cable is to be used then 3pin end of the cable is connected the relay plug and 4pin end of the cable is connected to the controller board. If 3-3A cable is to be used then either of the cable can be connected to the relay plug. Always ensure that black wire of the cable is connected to the G pin. In the below given pictures one can see 4-3A cable is used to connect relay plug to the Pluguino Board. The data pin of the relay plug is connected to the 6th GPIO pin on the controller board. By controlling the voltage at the 6th GPIO pin of the controller board one can control the relay.
In order to demonstrate the working of the relay plug, we are going to activate the relay plug for 2 seconds and deactivate it for another 2 seconds.
