HKE HRS4H-S-DC24V-C : Datasheet

The VCC input provides power for the drivers and the relay coils. 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.

What is Web Browser. Sign up using Facebook. 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.

Relays are sometimes used for their electrical isolation between their input the coil and their output the switch contacts. Choosing Battery for Robots.

Home Questions Tags Users Unanswered. The input section has a coil which generates magnetic field when a small voltage from an electronic circuit is applied to it.

Get inner details hsr4h structure of a relay switch.

What’s missing? Tell us about it.

Your Arduino most likely can’t drive that relay directly. The relays in the link you provided do not have a Vcc connection, and they have only 5 pins. Sign up using Email and Password. Arduino based GPS receiver.

บริษัท อีเลคทรอนิคส์ ซอร์ซ จำกัด

You have made an understandable mistake. Interface GPS with Arduino. I have googled with first result as a part’s datasheet with exact pinout. A simple low side NPN switch is usually the easiest way to control a relay from a digital output.

All you have there is a base relay. Olin Lathrop k 30 Skip to main content. There will be some finite resistance between the two coil leads, probably a few 10s of Hrs4n, maybe up to or two Ohms. They are very useful devices and allow one circuit to switch another one while they are completely separate. You aren’t going to be able to drive this relay directly from the digital output of a microcontroller.


Thus a small sensor circuit can drive, say, a fan or an electric bulb. Wolfe Jun 1 ’15 at As such, there is often a larger physical distance between these datashet sets of pins. Choosing Motor For Robots.

When the operating voltage is applied the relay coil gets energized and the COM changes contact to NO.

These ICs dataaheet driver chips, dc55v they are what actually drive the relays. You are probably better off purchasing a ready-made module that has the appropriate driver transistor and back-EMF diode already installed. To find out which is which, use a ohmmeter.

This guess is based on the fact that there are two of them grouped separately from the others. Commonly used relays are available in different configuration of operating voltages like 6V, 9V, 12V, 24V etc. This high-density System-in-Package SiP integrates controller, power switches, and support components.

Interface SD Card with Arduino.

By using proper combination of contactors, the electrical circuit can be switched on and off. What you have in your picture is a plain old relay.
