This voltage is called the operating voltage.

Since the common pin is determined, thus another one remaining pin in the connected pins detected in step 3 must be the normally closed Dafasheet pin.

You need to use simple amplifier to activate it. Introduction A relay is an electrically activated switch. 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. Feb 27, at Coil pins of the relay is determined in this case, the coil resistance is 70 ohm. Apr 9, at 4: Coil pins of the relay is determined in this case, the coil resistance is ohm.

Apr 17, at Apr 19, at 4: It has 6 pins: Get inner details about structure of a relay switch. Oct 23, at 6: Leave a comment Cancel reply.

Zero-ing the output voltage of power supply. Aug 28, at 1: Such relay is actually a combination of two SPST relay structures with only one coil pin pair. Nov 11, at 8: Thus, the other 2 remaining pins in the connected pins must be common pins.

Relay Switch Pin Diagram & Description

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. Connect the output terminal of power supply across the coil pins of relay using crocodile clips. Then, with the datashedt set to continuity test mode, check which pins now are connected to the normally open NO pin in this moment.

Hence, the 4th pin must be datawheet normally open NO pin.

Identify Terminal Pins of A Relay Without Reference to Datasheet

dtasheet May 26, at 6: Thank you for the clear, complete and easily understand tutorial. Mar 18, at 4: 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.

Jun 21, at Now, all the pins of relay have been determined as shown in Figure 16 below.

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 hrs4h-d-dc12v makes contact with the NO pin. Even in this is still usefull. Then, connect the output terminal of DC power supply across the coil pins of the relay using crocodile clips. Apr hrs4h-s-dc12g, at 5: There are some designations normally used in describing a relay based on its internal structure and pins distribution as shown in the following: Skip to main content.

Set the multimeter to resistance measuring mode with a scale of ohm since the coil resistance normally ranges between 50 ohm and ohm. Jan 27, at Nov 9, at In this case, although the activation voltage stated is DC 5V, the activation voltage recorded is about 3. Feb 10, at 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. Thanks a lot, i was looking for some explanations over internet, this is best!

Then, with the multimeter set to continuity test mode, check which pin is now connected to the normally open NO pin in this moment. 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. Thank you Suan Kian, thank you Cytron, excellent tutorial, good website. Apr 3, at 1: 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 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. Other pins approximately also at this values. The other 1 remaining pin in the connected pair datashedt be a common pin.

There is only 3 remaining pins to determine which are the NC pin, NO pin and common pin. Dec 12, at The input section has a coil which generates magnetic field when a small voltage from an electronic circuit is applied to it. Turn back the relay to see pins located at its bottom part.
