5v 1 Channel Relay Module Circuit Diagram

Let us learn how to use one in our circuits based on the requirement of our project.

5v 1 channel relay module circuit diagram. It can be used to control various appliances and equipment with large current. It is equipped with high current relays that work under ac250v 10a or dc30v 10a. 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. Ky 020 arduino tilt switch sensor module.

It can be used to control various appliances and equipment with large current. In power system and high voltage system the lower current can control the higher one. Relays are most commonly used switching device in electronics. 5v and gnd and connect the control signal from arduino to control.

The features of 1 channel relay module are as follow. 5 volt relay i used 6 volt because i need 6 volt relay 2. Relay driver circuit explanation. How to use a relay.

Here we have used 12v 10amp relay in this pcb board but you can also use 5v relays. It can be used to control various appliances and equipment with large current. 0 45 113 orders. 3v relay 12v relay 1 channel relay module 4 channel relay module.

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. Being able to control high load current which can reach 240v 10a. Although the circuit diagram explains the detailed connections practically we didn t need to make all the connections. It is equiped with high current relays that work under ac250v 10a or dc30v 10a.

1 channel high voltage system output meeting the needs of single channel control. 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. 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.

Before we proceed with the circuit to drive the relay we have to consider two important parameter of the relay. 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. 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. 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.

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.
