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.

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 dataxheet Arduino.

Choosing Motor For Robots. All you have there is a base relay. Interface GPS with Arduino.

HRS4H-(S)-DC5V Datasheet PDF –

There are d5v questions here already on that topic, so no need to repeat the details in this answer. This high-density System-in-Package SiP integrates controller, power switches, and support components. These ICs are driver chips, and they are what actually drive the relays. The hts4h between each of these pins and any of the other three will be infinite. They are very useful devices and allow one circuit to switch another one while they are completely separate. Choosing Battery for Robots.

Guessing from the layout of the pins shown in your picture, the coil pins are the two at right. That module you saw probably has at the very least a transistor included to actually drive the relay. Olin Lathrop k 30 Email Required, but never shown. If you don’t have an Arduino, you obviously don’t have an Arduino pin 7 to drive the relay.

Wolfe Jun 1 ’15 at Your Arduino most likely can’t drive that relay directly.

Here’s your relay’s datasheet: As such, there is often a larger physical distance between these two sets of datashewt. You aren’t going to be able to drive this relay directly from the digital output of a microcontroller. Do you have a part number? WhatRoughBeast 49k 2 28 Post as a guest Name.

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

So the module as a whole has 10 pins. Flip the relay over and look at what is printed on the top.

Relay Switch Pin Diagram & Description

A simple low side NPN switch is usually the easiest way to control a relay from a digital output. If you don’t have somebody local to you to help you through this project, you are better off with the pre-manufactured module. Relay is an electromagnetic device which is used to isolate two circuits electrically and connect them magnetically.

Your relay has 5 pins, which are almost certainly the two connections to the coil, and the common COMnormally-open NOand normally-closed NC connections of the switch. This will often tell you the voltage or current the coil requires to activate the switch, and what the switch is rated for.
