5v Relay Board Circuit Diagram

We have put a three pin screw terminal blocks nc nuteral no for connecting appliances.
5v relay board circuit diagram. 3 ways to test a relay wikihow how to wire a raspberry pi to a sainsmart 5v relay board raspberry. Ad blocker detected thanks for supporting. In this circuit we have designed an isolated pcb for 4 relays. This is a 5v 8 channel relay interface board be able to control various appliances and other equipment with large current.
Required components arduino uno or any other arduino board 5v relay 1n4007 diode. Current limited 230v led bulb with flux led schematic circuit diagram. This switch can be anything from a small transistor to a microcontroller or a microprocessor which can perform switching operating. In the above circuit 5v relay is powered by a 9v battery.
Even though we have used a 5v relay module the connections in this circuit diagram will be describe the complete setup. An on off switch is added for the switching purpose of the relay. 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. For demonstrating the working of this relay module we have used an arduino uno board for controlling relays.
The above circuit shows a bare minimum concept for a relay to operate. Smps power supply spp34 schematic 12v 5v 2a schematic circuit diagram. Metering and instrument circuits. It can be controlled directly by micro controller raspberry pi arduino 8051 avr pic dsp arm arm msp430 ttl logic 5v 8 channel relay interface board and each one needs 15 20ma driver current.
It is equipped with high current relays that work under ac250v 10a or dc30v 10a. By using this relay board we can operate 4 ac appliances at a time. Lights and display board circuits. 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.
Below are the circuit diagram and pcb layout designs of the relay driver. Let us see the circuit diagram for the project. 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. It can be used to control various appliances and equipment with large current.
Relay and relay circuits schematic circuit diagram. For more details about this circuit and design. At the initial condition when switch is open no current flow through coil hence common port of relay is connected to no normally open pin so the. Here we have used 12v 10amp relay in this pcb board but you can also use 5v relays.
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.
