5v 1 Channel Relay Module Circuit Diagram

Here we have used 12v 10amp relay in this pcb board but you can also use 5v relays.

5v 1 channel relay module circuit diagram. Being able to control high load current which can reach 240v 10a. Also the electrical paths for the ac lines on the relay module should be wide enough min 3mm as short as possible separated from any other path on the pcb and not too close to each other. Now we need to collect some parts that we needed to make the diy relay module. In this 4 channel relay driver circuit we have used an optocoupler whic his triggered by active low signal to trigger the npn transistor which further drives the relay.

Although the circuit diagram explains the detailed connections practically we didn t need to make all the connections. 5v and gnd and connect the control signal from arduino to control. Relay driver circuit explanation. The features of 1 channel relay module are as follow.

Before we proceed with the circuit to drive the relay we have to consider two important parameter of the relay. It can be used to control various appliances and equipment with large current. 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. 177 orders ky 019 5v one 1 channel relay module board shield for pic avr dsp arm.

3v relay 12v relay 1 channel relay module 4 channel relay module. This is a low level 5v 2 channel relay interface board and each channel needs a 15 20ma driver current. It can be used to control various appliances and equipment with large current. 4 if the relay should switch ac loads the use of an opt isolator is recommended to separate the control circuit from the switching circuit relay.

It is equiped with high current relays that work under ac250v 10a or dc30v 10a. It is equipped with high current relays that work under ac250v 10a or dc30v 10a. 4 channel 5v optical isolated relay module this is a low level 5v 4 channel relay interface board and each channel needs a 15 20ma driver current. For the dc part of the circuit connect s signal to pin 10 on the arduino also connect the power line and ground to 5 and gnd respectively.

5 volt relay i used 6 volt because i need 6 volt relay 2. In power system and high voltage system the lower current can control the higher one. 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. Let us learn how to use one in our circuits based on the requirement of our project.

Wide range of controllable voltage. How to use a relay. It can be used to control various appliances and equipment with large current. Most relay modules whether 5v or 12v will come with the aforementioned connection and hence all you need is to give power supply to the relay module i e.

Relays are most commonly used switching device in electronics.
