There are many questions here already on that topic, so no need to repeat the details in this answer. What you have in your picture is a plain old relay.

The input section has a coil which generates magnetic field when a small voltage from an electronic circuit is applied to it. Flip the relay over and look at what is printed on the top.

Jun 1 ’15 at Thus a small sensor circuit can drive, say, a fan or an electric bulb. That module you saw probably has at the very least a transistor included to actually drive the relay. Email Required, but never shown. The relays in the link you provided do not have a Vcc connection, and they have only 5 pins. Relay is an electromagnetic device which is used to isolate two circuits electrically and connect them magnetically.

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

This guess is based on the fact that there are two of them hrs4b separately from the others. Hre4h will often tell you the voltage or current the coil requires to activate the switch, and what the switch is rated for. If you don’t have somebody local to you to help you through this project, you are better off with the pre-manufactured module. Here’s your relay’s datasheet: This voltage is called the operating voltage. So the module as a whole has 10 pins.


Post as a guest Name. What is the problem?

You are probably better off purchasing a ready-made module that has the appropriate driver transistor and back-EMF diode already installed. When the operating voltage is applied the relay coil gets energized and the COM changes contact to NO. By using proper combination of contactors, the electrical circuit can be switched on and off. Arduino based GPS receiver. Skip to main content.

That instructable is using a program in the Arduino to control the relay by setting the Arduino’s pin 7 high or low. The NO pin will have infinite reistance to all other pins. They are often used to interface an electronic circuit working at a low voltage to an electrical circuit which works at very high voltage.

Your relay has 5 pins, which are almost darasheet the two connections to the coil, and the common COMnormally-open NOand normally-closed NC connections of the switch. Olin Lathrop k 30 Choosing Battery for Robots. SPI Module of Arduino.

Guessing from the layout of the pins shown in your picture, the coil pins are the two at right.

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

The VCC input provides power for the drivers and the relay coils. To find out which is which, use a ohmmeter. These ICs are driver chips, and they are what actually drive the relays. You should not attempt to drive the relay directly from a microcontroller output pin, as they can’t provide enough current – you would use a micro output pin to control a transistor, which in turn would drive the relay.


Sign up using Facebook. Relays are sometimes used for their electrical isolation between their input the coil and their output the switch contacts. Wolfe Jun 1 ’15 at They are very useful devices and allow one circuit to switch another one while they are completely separate.

Interface SD Card with Arduino. And I have no idea why your module can run without connecting ground. Choosing Motor For Robots. As such, there is often a larger physical distance between these two sets of pins. Virgin Galactic — Commercial Space Flight. Sign up or log in Sign up using Google.

HKE HRS4H-S-DC24V-C : Datasheet

Do you have a part number? WhatRoughBeast 49k 2 28 You aren’t going to be able to drive this relay directly from the digital output of a microcontroller. Commonly used relays are available in different configuration of operating voltages like 6V, 9V, 12V, 24V etc.

Your Arduino most likely can’t drive that relay directly.
