5v Relay Board Circuit Diagram

Below are the circuit diagram and pcb layout designs of the relay driver.

5v relay board circuit diagram. Ad blocker detected thanks for supporting. 3 ways to test a relay wikihow how to wire a raspberry pi to a sainsmart 5v relay board raspberry. Lights and display board circuits. It can be used to control various appliances and equipment with large current.

Even though we have used a 5v relay module the connections in this circuit diagram will be describe the complete setup. Smps power supply spp34 schematic 12v 5v 2a schematic circuit diagram. The above circuit shows a bare minimum concept for a relay to operate. This switch can be anything from a small transistor to a microcontroller or a microprocessor which can perform switching operating.

For demonstrating the working of this relay module we have used an arduino uno board for controlling 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. 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. An on off switch is added for the switching purpose of the relay.

This is a 5v 8 channel relay interface board be able to control various appliances and other equipment with large current. In the above circuit 5v relay is powered by a 9v battery. Relay and relay circuits schematic circuit diagram. 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.

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. For more details about this circuit and design. Relay switch circuit diagram working of the basic 5v relay circuit.

Here we have used 12v 10amp relay in this pcb board but you can also use 5v relays. In this circuit we have designed an isolated pcb for 4 relays. Metering and instrument circuits. We have put a three pin screw terminal blocks nc nuteral no for connecting appliances.

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. All four relays are connected with arduino at 8 9 10 and 11th pins in1 in2 in3 and in4 and 1 12v adapter is used for. 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. It is equipped with high current relays that work under ac250v 10a or dc30v 10a.
