Flip the relay over and look at what is printed on the top. By clicking “Post Your Answer”, you acknowledge that you have rc5v our updated terms of serviceprivacy policy and cookie policyand that your continued use of the website is subject to these policies. You aren’t going to be able to drive this relay directly from the digital output of a microcontroller.

Jun 1 ’15 at The resistance between each of datashheet pins and any of the other three will be infinite.

To find out which is which, use a ohmmeter. What you have in your picture is a plain old relay.

The VCC input provides power for the drivers and the relay coils. The output section consists of contactors which connect or disconnect mechanically.

Virgin Galactic — Commercial Datashet Flight. If you don’t have somebody local to you to help you through this project, you are better off with the pre-manufactured module. You have made an understandable mistake.


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. SPI Module of Arduino. Relays are sometimes used for their electrical isolation dztasheet their input the coil and their output the switch contacts. Get inner details about structure of vc5v relay switch. This will often tell you the voltage or current the coil requires to activate the switch, and what the switch is rated for.

Skip to main content. Your Arduino most likely can’t drive that relay directly. So the module as a whole has 10 pins. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

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

When the operating voltage is applied the relay coil gets energized and the COM changes contact to NO. Do you have a part number? There will be some finite resistance between the two coil leads, probably a few 10s of Ohms, maybe up to or two Ohms.

As such, there is often a larger physical distance between these two sets of pins. In a basic relay there are three contactors: It may be that you are connecting it to the power supply ground that also connects to the Arduino, but in that case you are, in fact, electrically connecting it to the Arduino. 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.


A simple low side NPN switch is usually the easiest way to control a relay from a digital output. What is the problem? The NO pin will have infinite reistance to all other pins.

Commonly used relays are available in different configuration of operating voltages like 6V, 9V, 12V, 24V etc. Post as a guest Name.

Sign up or log in Sign up using Google. Here’s your relay’s datasheet: The input section has a coil which generates magnetic field when a small voltage from an electronic circuit is applied to it. They are very useful devices and allow one circuit to switch another one while they are completely separate.

This high-density System-in-Package SiP integrates controller, power switches, and support daatasheet. Your relay has 5 pins, which are almost certainly the two connections to the hrs4, and the common COMnormally-open NOand normally-closed NC connections datasueet the switch. This guess is based on the fact that there are two of them grouped separately from the others. Choosing Motor For Robots. Choosing Battery for Robots.

That module you saw probably has at the very least a transistor included to actually drive the relay. Interface GPS with Arduino. They are often used to interface an electronic circuit working at a low voltage to an electrical circuit which works at very high voltage.
