Zero-ing the output voltage of power supply 6. Apr 3, at 1: Based on this finding, the remaining pins must be normally open NO pins. 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. Other pins approximately also at this values.

Feb 19, at 1: May 29, at 2: The required activation voltage for the relay can be determined from its product code. Good work, keep it up….

Connect the output terminal of power supply across hrs4h-s-dc12vv coil pins of relay using crocodile clips Figure Oct 2, at 9: 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 26, at 9: 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.

Nov 29, at 3: Dec 12, at Nov 11, at 8: Jan 28, at 8: Various normal designations of relay. Jun 21, at Coil pins of the relay is determined in this case, the coil resistance is 70 ohm 3. That pin would be the common pin.

Relay Switch

Hence, the 3rd pin must be the normally open NO pin. Then, with the multimeter set to continuity test mode, check which pins now are connected to the normally open NO pin in this moment. 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. A relay is an electrically datashedt switch.

Such relay is actually a combination of two SPST relay structures with only one coil pin pair. 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 hrs4h-s-dc12f.

Dec 21, at In this case, although the activation voltage stated is DC 12V, the activation voltage recorded is about 7. Coil pins of the relay is determined in this case, the coil resistance is 70 ohm.

Such relay is actually a combination of two SPDT relay structures with only one coil pin pair.

Apr 16, at 2: Thanks a lot, i was looking for some explanations over internet, this is best! This is really useful for me to understand how to identify a relay. Such relay can categorized into normally open or normally closed type.

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

So, i connected them to Arduino UNO pins and only 1 relay worked. Aug 28, at 1: Turn back the relay to see pins located at its bottom part. Jan 27, at Coil datasheeg of the relay is determined in this case, the coil resistance is ohm.

Apr 17, at The part of product code indicates relay activation voltage. Determine the common pin of the relay when the relay is activated.

These pins would be the common pins. Does Icc needs more current for 4-channel? Now, all the pins of relay have been determined as shown in Figure 23 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.
