When the operating voltage is applied the relay coil gets energized and the COM changes contact to NO. All you have there is a base relay.

Interface SD Card with Arduino. A simple low side NPN switch is usually the easiest way to control a relay from a digital output. Sign up using Email and Password. Flip the relay over and look at what is printed on the top.

Relay Switch

Email Required, but never shown. In a datxsheet relay there are three contactors: WhatRoughBeast 49k 2 28 The input section has a coil which generates magnetic field when a small voltage from an electronic circuit is applied to it. SPI Module of Arduino. If you don’t have somebody local to you to help you through this project, you are better off with the pre-manufactured module. Virgin Galactic — Commercial Space Flight. Relay is an electromagnetic device which is used to isolate two circuits electrically and connect them magnetically.


Interface GPS with Arduino.

find VCC, GND and IN in relay – Electrical Engineering Stack Exchange

Home Questions Tags Users Unanswered. I have googled with first result as a part’s datasheet with exact pinout.

By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service. They are datwsheet used to interface an electronic circuit working at a low voltage to an electrical circuit which works at very high voltage.

If you don’t have an Arduino, you obviously don’t have an Arduino pin 7 to drive the relay. To find dagasheet which is which, use a ohmmeter. You have made an understandable mistake. The NO pin will have infinite reistance to all other pins. Guessing from the layout of the pins shown in your picture, the coil pins are the two at right.

The VCC input provides power for the drivers and the relay coils. This will often tell you the voltage or current the coil requires to activate the switch, and what the switch is rated for.

Choosing Motor For Robots.

This voltage is called the operating voltage. Jun 1 ’15 at Your Arduino most likely can’t drive that relay directly.


This guess is based on the fact that there are two of them grouped separately from the others. 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. Do you have a part number?

HKE HRS4H-S-DC24V-C : Datasheet

There are many questions here already on that topic, so no need to repeat the details in this answer. Here’s your relay’s datasheet: Olin Lathrop k 30 You aren’t going to be able to drive this relay directly from the digital output of a microcontroller.

What is Web Browser. That module you saw probably has at the very least a transistor included to actually drive the relay.

(PDF) HRS4H-S-DC5V Datasheet download

Commonly used relays are available in different configuration of operating voltages like 6V, 9V, 12V, 24V etc. And I have no idea why your module can run without connecting ground. Relays are sometimes used for their electrical isolation between their input the coil and their output the switch contacts.
