Apr 16, at Nov 29, at 3: Thank you for the clear, complete and easily understand tutorial.
They are hr4sh-s-dc12v useful devices and allow one circuit to switch another one while they are completely separate. Apr 8, at 5: Introduction A relay is an electrically activated switch.
Various normal designations of relay Relays that are normally used in electronic circuits are SPDT and DPDT types due to their flexibility in controlling circuit switching. Now, all the pins of relay have been determined as in Figure 9 below.
บริษัท อีเลคทรอนิคส์ ซอร์ซ จำกัด
Jul 24, at 2: When the operating voltage is applied the relay coil gets energized and the COM changes contact to NO. Based on this finding, the remaining pins must be normally open NO pins. Various normal designations of relay.
By using proper combination of contactors, the electrical circuit can be switched on and off. Feb 4, at 8: Nov 9, at Thanks a lot, i was looking for some explanations over internet, this is best! Dec 12, at 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.
Now, all the pins of relay have been determined as shown in Figure 16 below. They are often used to interface an electronic circuit working at a low voltage to an electrical circuit which works at very high voltage. Even in this is still usefull. Other pins approximately also at this values. 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.
Identify Terminal Pins of A Relay Without Reference to Datasheet
This high-density System-in-Package SiP integrates controller, power switches, and support components. May 26, at 6: 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 determined from its product code in the section of code enclosed with a dash which contains a number suffixed with VDC as shown below. Determine the common pin of the relay when the relay is activated 9. 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. Hence, the 4th pin must be the normally open NO pin.
Oct 2, at 9: Then, connect the output terminal of DC power supply across the coil pins of the relay using crocodile clips.
Jan 28, at 8: Feb 19, at 1: This voltage is called the operating voltage. Apr 17, at Nov 11, at 8: Coil pins of the relay is determined in this case, the coil resistance is ohm.
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. Apr 3, at 1: Commonly used relays are available in different configuration of operating voltages like 6V, 9V, 12V, 24V etc. Try to touch the probes of multimeter on remaining pins to determine which are the pins actually connected with each other.
Now, all the pins of relay have been determined as shown in Figure 23 below.
Zero-ing the output voltage of power supply 6. Set your multimeter to continuity test mode. More posts by Suan Kian. Jun 11, at 8: Thus a small sensor circuit can drive, say, a fan or an electric bulb. Apr 16, at 2: Relay have become a common use electronic component which operate as an switching device by simply apply voltage to ON and OFF it.
Turn back the relay to see pins located at its bottom part. 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.
