5v Relay Board Circuit Diagram

8 channel 5v optical isolated relay module this is a low level 5v 8 channel relay interface board and each channel needs a 15 20ma driver current.

5v relay board circuit diagram. This switch can be anything from a small transistor to a microcontroller or a microprocessor which can perform switching operating. 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. Here we have used 12v 10amp relay in this pcb board but you can also use 5v relays. Even though we have used a 5v relay module the connections in this circuit diagram will be describe the complete setup.

This is single channel 5v relay module for arduin. Now we need to collect some parts that we needed to make the diy relay module. An on off switch is added for the switching purpose of the relay. It is equipped with high current relays that work under ac250v 10a or dc30v 10a.

A normally open configuration works the other way in which the relay is always open until you send a signal from the arduino to the relay module to close the circuit. Ac supply relay switch circuit diagram working of the basic 5v relay circuit. Most of the parts was lying around my home i used to save little more here the list of all the parts you needed to do this project. In the above circuit 5v relay is powered by a 9v battery.

Diy homemade 5v single channel relay module shield for arduino pic avr raspberry pi features 1. Required components arduino uno or any other arduino board 5v relay 1n4007 diode. It can be used to control various appliances and equipment with large current. A set of wiring diagrams may be required by the electrical inspection authority to implement membership of the house to the public electrical supply system.

The above circuit shows a bare minimum concept for a relay to operate. Control pins on the other side of the module there are four pins a ground pin and a vcc pin to power the module and two input pins in1 and in2 to control. 3 ways to test a relay wikihow how to wire a raspberry pi to a sainsmart 5v relay board raspberry. Since the arduino operates at 5v it can t control these higher voltage devices directly but you can use a 5v relay to switch the 120 240v current and use the arduino to control the relay.

The arduino can be programmed to turn on the relay when a certain event occurs for example when the temperature of a thermistor gets higher than 30 c. Let us see the circuit diagram for the project. 5 volt relay i used 6 volt because i need 6 volt relay 2.
