Various normal designations of relay. Try to touch the probes hrs4h-s–dc12v multimeter on a pair of pins of relay until the touched pair shows a resistance value but not zero. That pin would be the common pin. The required activation voltage for the relay can be determined from its product code.
By using proper combination of contactors, the electrical circuit can be switched on and off.

Apr 3, at 1: There is only 3 remaining pins to determine which are the NC pin, NO pin and common pin. Relay is an electromagnetic device which is used to isolate two circuits electrically and connect them magnetically. Connect the output terminal of power supply across the coil pins hrs4h-s-dc12c relay using crocodile clips Figure 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.
The other 1 remaining pin in the connected pair must be a common pin. Find Us on Facebook.
Identify Terminal Pins of A Relay Without Reference to Datasheet
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. Skip to main content.
This high-density Datashert SiP integrates controller, power switches, and support components. Now, all the pins of relay have been determined as in Figure 9 below. So, i connected them to Arduino UNO pins and only 1 relay worked. Even in this is still usefull. They are very useful devices and allow one circuit to hrd4h-s-dc12v another one while they are completely separate.
Apr 9, at 4: What is Web Browser. The output section consists of contactors which connect or disconnect mechanically. In this case, although the activation voltage stated is DC 12V, the activation voltage recorded is about 7. Turn back the relay to see pins located at its bottom part.
Then, with the multimeter set to continuity test mode, check which pin in each connected pin pair datashest in step catasheet now are connected with a particular normally open NO pin at this moment since 2 normally open NO pins are found in step 3. Such relay is actually a combination of two SPDT relay structures with only one datashfet pin pair. Thank you for the clear, complete and easily understand tutorial. Feb 19, at 1: Try to touch the probes of multimeter on remaining pins to determine which are the pins actually connected with each other.
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. Feb 27, at 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.
In this case, although the activation voltage stated is DC 5V, the activation voltage recorded is about 3.
Choosing Battery for Robots. Choosing Motor For Robots. Arduino based GPS receiver. Try to touch the probes of multimeter on a pair of pins of the datasheft until the touched pair shows a resistance value but not zero.
Apr 17, at Other pins approximately also at this values. Apr 8, at 5: Relay have become a common use electronic component which operate as an switching device by simply apply voltage to ON and OFF it. 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 datassheet.
Good work, keep it up….
Try to touch the probes of multimeter on remaining pins to determine which are the pins actually connected to each other. The required activation voltage for the relay can be datasheet from its product code in the section of code enclosed with a dash which contains a number suffixed with VDC as shown below.
Jan 28, at 8: Feb 26, at 9: Such relay is actually a combination of two SPST relay structures with only one coil pin pair. Aug 28, at 1: May 29, at 2: Dec 21, at Apr 16, at May 26, at 6: 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.
