By using proper combination of contactors, the electrical circuit can be switched on and off. This guess is based on the fact that there are two of them grouped separately from the others.

That module you saw probably has at the very least a transistor included to actually drive the relay. WhatRoughBeast 49k 2 28 Choosing Motor For Robots. Post Your Answer Discard By clicking “Post Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and cookie policyand that your continued use of the website is subject to these policies. Email Required, but never shown. A simple low side NPN switch is usually the easiest way to control a relay from a digital output.

HKE HRS4H-S-DC24V-C : Datasheet

The relays in the link you provided do not have a Vcc connection, and they have only 5 pins. If you don’t have somebody local to you to help you through this project, you are better off with the pre-manufactured module. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service. Jun 1 ’15 at Datasgeet relay has 5 pins, which are almost certainly the two connections to the coil, dataseet the common COMnormally-open NOand normally-closed NC connections of the switch.


This voltage is called the operating voltage. Interface SD Card with Arduino.

And I have no idea why your module can run without connecting ground. As such, there is often a larger physical distance between these two sets of pins. There are many questions here already on that topic, so no need to repeat the details in this answer.

They are often used to interface an electronic circuit working at a low voltage to an electrical circuit which works at very high voltage. Olin Lathrop k 30 Arduino based GPS receiver. Sign up or log in Sign up using Google. Interface GPS with Arduino. This will often tell you the voltage or current the coil requires to activate the switch, and what the switch is rated for. Virgin Galactic — Commercial Space Flight.

Wolfe Jun 1 ’15 at The NO pin will have infinite reistance datashheet all other pins. I have googled with first result as a part’s datasheet with exact pinout. They are very useful devices and allow one circuit to switch another one while they are hrs4j separate. The output section consists of contactors which connect or disconnect mechanically. Post as a guest Name. The resistance between each of these pins and any of the other three will be infinite. Do you have a part number?

So the module as a whole has 10 pins. You are probably better off purchasing a ready-made module that has the appropriate driver datashet and back-EMF diode already installed.

Sign up using Email and Password. The input section has a coil which generates magnetic field when a small voltage from an electronic circuit is applied to it.


What is Web Browser. Relays are sometimes used for their electrical isolation between their input the coil and their output the switch contacts. In a basic relay there are datashert contactors: What is the problem?

Relay Switch

Home Questions Tags Users Unanswered. Here’s your relay’s datasheet: What you have in your picture is a plain old relay. You aren’t going to be able to drive this relay directly from the digital output of a microcontroller. Flip the relay over and look at what is printed on the top.

The VCC input provides power for the drivers and the relay coils. By clicking “Post Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and cookie policyand that your continued use of the website is subject to these policies.

If you don’t have an Arduino, you obviously don’t have an Arduino pin 7 to drive the relay.

Skip to main content. Commonly used relays are available in different configuration of operating voltages like 6V, 9V, 12V, 24V etc. SPI Module of Arduino. This high-density System-in-Package SiP integrates controller, power switches, and support components. To find out which is which, use a ohmmeter. You have made an understandable mistake. When the operating voltage is applied the relay coil gets energized and the COM changes contact to NO. Guessing from the layout of the pins shown in your picture, the coil pins are the two at right.
