A relay is an electrically activated switch. It consists of an internal coil which creates a magnetic field that attracts a movable lever and then changes switch contacts when a current flows through it. The typical usage of relay is to allow a low DC voltage circuit circuit 1 to switch on or off a high voltage DC or AC circuit circuit 2 without direct electrical connection between them. This means circuit 1 and circuit 2 are magnetically and mechanically linked but not electrically connected.

There are some designations normally used in describing a relay based on its internal structure and pins distribution as shown in the following: Such relay can categorized into normally open or normally closed type. When the relay is not activated, the common pin is in contact with the NC pin and when it is activated, the common pin will break away from contact with the NC pin and subsequently makes contact with the NO pin.

Also, when the relay is deactivated from activated statethe common pin will conversely break away from contact with the NO pin and return back in contact with the NC pin. Such relay is actually a combination of two SPST relay structures with only one coil pin pair.

Such relay is actually a combination of two SPDT relay structures with only one coil pin pair. Various normal designations of relay. A 5-pins type relay, a 6-pins type relay and an 8-pins type relay will be used in this demonstration. Set the multimeter to resistance measuring mode with a scale of ohm since the coil resistance normally ranges between 50 ohm and ohm. Turn back the relay to see pins located at its bottom part.

Try to touch the probes of multimeter on a pair of pins of the relay until the touched pair shows a resistance value but not zero. Coil pins of the relay is determined in this case, the coil resistance is 70 ohm.

Since the coil pin pair is found. There is only 3 remaining pins to determine which are the NC pin, NO pin and common pin.

Set your multimeter to continuity test mode. Try to touch the probes of multimeter on remaining pins to determine which are the pins actually connected with each other. Based on this finding, the remaining pins must be normally open NO pins. Hence, the 3rd pin must be the normally open NO pin.

The other 1 remaining pin in the connected pair must be a common pin. 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. 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.

The darasheet of product code indicates relay activation voltage. Turn on the DC power supply. Without connecting its output terminal to coil pins of the relay, please turn the voltage adjusting knobs until the voltage reading reaches the zero value. Zero-ing the output voltage of power supply. Then, connect the output terminal of DC power supply across the coil pins of the relay using crocodile clips. Normally, for this kind of relays, the location of the coil pins will be marked as well as their polarity to prevent any mistaken connection that could destroy the relays that have been made.

In this case, although the activation voltage stated is DC 5V, the activation voltage recorded is about 3. Hrs4h-d-dc12v the output terminal of power supply across the coil pins of relay using crocodile clips. Activation voltage of the relay during this demonstration. Then, with the multimeter set to continuity test mode, check which pin is now connected to the normally open NO pin in rhs4h-s-dc12v moment. That pin would be the common pin. Determine datashfet common pin of the relay when the relay is activated.

Since the common pin is determined, thus another one remaining pin in the connected pins detected in step 3 must be the normally closed NC pin. Now, all the pins of relay have been determined as in Hsr4h-s-dc12v 9 below. Try to touch hrs4h-d-dc12v probes of multimeter on a pair of pins of relay until the touched pair shows a resistance value but not zero. Coil pins of the relay is determined in this case, the coil resistance is ohm. Try to touch the probes of multimeter on remaining pins to determine which are the pins actually connected hrs4g-s-dc12v each other.

Hence, the 4th pin must be the normally open NO pin. Thus, the other 2 remaining pins in the connected pins must be common pins.

What’s missing? Tell us about it.

To differentiate NC pins and common pins from the connected pins, there is a need to apply voltage across the relay coil so as to activate it. The required activation voltage for the relay can be determined from its product code.

Then, connect the output terminal of the DC power supply across the coil pins of the relay using crocodile clips. 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. In this case, although the activation voltage stated is DC 12V, the activation voltage recorded is about 7.

Then, with the multimeter set to continuity test mode, check which pins now are connected to the normally open NO pin in this moment.

These pins would be the common pins. 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.

Now, all the pins of relay have been determined as shown in Figure 16 below. To differentiate NC pins and common pins from in the connected pins. Hence, the positive output of the DC power supply can be connected to any one of the coil pins while the negative output of DC power supply will be connected to another pin of coil or vice versa.

In this case, although the activation voltage stated is DC 12V, the activation voltage recorded is about 3. Then, with the multimeter set to continuity test mode, check which pin in each connected pin pair detected in step 3 now are connected with a particular normally open NO pin at this moment since 2 normally open NO pins are found in step 3.

Since the common pins are determined, thus another one remaining pin in the connected pins detected in step 3 must be the normally closed NC pin. Now, all the pins of relay have been determined as shown in Figure 23 below. After going through above demonstrations, users must have became familiar with the ways or steps to determine the terminal pins of a relay even though there is no datasheet for reference.

Relay have become a common use electronic component which operate as an switching device by simply apply voltage to ON and OFF it. For this project, we will discover a simple relay connected with an LED to show what is the basic function and connection.

Thanks a lot, i was looking for some explanations over internet, this is best! Good work, keep it up…. There is a 4-channel relay module. It has 6 pins: So, i connected them hgs4h-s-dc12v Arduino UNO pins and only 1 relay worked. Other pins approximately also at this values.

Does Icc needs more current for 4-channel? You need to use simple amplifier to activate it. Even in this is still usefull. Thank you for the clear, complete and easily understand tutorial.

This is really useful for me to understand how to identify a relay. If you want to know how to make extra bucks, search for: Excellent explanation, this helped me determine the pins on my relay for which its datasheet I was utterly unable to find, thanks! Introduction A relay is an electrically activated switch.
