In a basic relay there are three contactors: Sign up or log in Sign up using Google. A simple low side NPN switch is usually the easiest way to control a relay from a digital output. Skip to main content.

Relay Switch Pin Diagram & Description

By using proper combination of contactors, the electrical circuit can be switched on and off. Olin Lathrop k 30 To find out which is which, use a ohmmeter. When the operating voltage is applied the relay coil gets energized and the COM changes contact to NO. SPI Module of Arduino. Email Required, but never shown.


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.

Post as a guest Name. Relays are sometimes used for their electrical isolation between their input the coil and their output the switch contacts. What you have in your picture is a plain old relay.

Relay Switch

The VCC input provides power for the drivers and the relay coils. As such, there is often a larger physical distance between these two sets of pins. These ICs are driver chips, and they are what actually drive the relays. I have googled with first result as a part’s datasheet with exact pinout. Arduino based GPS receiver. That module you saw probably has at the very least a transistor included to actually drive the relay. The output section consists of contactors which connect or disconnect mechanically.

Sign up using Facebook. This high-density System-in-Package SiP integrates controller, power switches, hrs4g support components. Guessing from the ss of the pins shown in your picture, the coil pins are the two at right. Dwtasheet SD Card with Arduino.


That instructable is using a program in the Arduino to control the relay by setting the Arduino’s pin 7 high or low.

The resistance between each of these pins dataxheet any of the other three will be infinite. The relays in the link you provided do not have a Vcc connection, and they have only 5 pins.

This voltage is called the operating voltage.

Home Questions Tags Users Unanswered. Wolfe Jun 1 ’15 at What is the problem? Get inner details about structure of a relay switch. If you don’t have somebody local to you to help you through this project, you are better off with the pre-manufactured module.

All you have there is a base relay.
