Connect the output terminal of power supply across the coil pins of relay using crocodile clips Figure For this project, we will discover a simple relay connected with an LED to show what is the basic function and connection.
What’s missing? Tell us about it.
Good work, keep it up…. A relay is an electrically activated switch.
Apr 19, at 4: Coil pins of the relay is determined in this case, the coil resistance is ohm. May 11, at 5: In this case, although the activation voltage stated is DC 5V, the activation voltage recorded is about 3. Try to touch the probes of multimeter on remaining pins datasheef determine which hrs4h-s-dc12vv the pins actually connected to each other.
When the operating voltage is applied the relay coil gets hhrs4h-s-dc12v and the COM changes contact to NO. Feb 27, at datasheeet Jan 28, at 8: To differentiate NC pin and common pin from the connected pins, there is a need to apply voltage across the relay coil so as to activate it.
Oct 2, at 9: Turn back the relay to see pins located at its bottom part. Aug 28, at 1: Feb 10, at Jun 11, at 8: Since the common pins are determined, thus another one remaining pins in the connected pins detected in step 3 must be the normally closed NC pins. SPI Module of Arduino.
Jun 21, at Feb 19, at 1: The output section consists of contactors which connect or disconnect mechanically. These pins would be the common pins. Set the multimeter to resistance measuring mode with a scale of ohm since the coil resistance normally ranges between 50 ohm and ohm. If you want to know how to make extra bucks, search for: In this case, although the activation voltage stated is DC 12V, the activation voltage recorded is about 3.
Thank you Suan Kian, thank you Cytron, excellent tutorial, good website. Get inner details about structure of a relay switch.
Since the coil pin pair is found. The required activation voltage for the relay can be determined from its product code in the section of code enclosed with a dash which contains a number suffixed with VDC as shown below.
Now, all the pins of relay have been determined as shown in Figure 23 below. Thus, the other 2 remaining pins in the connected pins must be common pins.
In this case, although the activation voltage stated is DC 12V, the activation voltage recorded is about 7. They are often used to interface an electronic circuit working at a low voltage to an electrical circuit which works at very high voltage. Zero-ing the output voltage of power supply 6.
Then, connect the output terminal of the DC power supply across the coil pins of the relay using crocodile clips. Various normal designations of relay Relays that are normally used in electronic circuits are SPDT and DPDT types due to their flexibility datasheeet controlling circuit switching.

Connect the output terminal of power supply across the coil pins of relay using crocodile clips Figure 7: Hence, the positive output of the DC power supply can be connected to any one of the coil pins while negative output of DC power supply will be connected to another pin of coil or vice versa.
Activation voltage of the relay during this demonstration 8. Connect the output terminal of power supply across the coil pins hrs4h-s-xc12v relay using crocodile clips. Project 14 — Interface with Relay Relay have become a common use electronic component which operate as an switching device by simply apply voltage to ON and OFF it.
