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. Arduino based GPS receiver. Hence, the 3rd pin must be the normally open NO pin.
That pin would be the common pin. A 5-pins type relay, a 6-pins type relay and an 8-pins hrs4h-s-dc12f relay will be used in this demonstration.
Relay Switch Pin Diagram & Description
Good work, keep it up…. Then, with the multimeter set to continuity test mode, check which pins now are connected to the normally open NO pin in this moment. When the operating voltage is applied the relay coil gets energized and the COM changes contact to NO.
Apr 9, at 4: There datashwet a 4-channel relay module. Coil pins of the relay is determined in this case, the coil resistance is 70 ohm. Jul 24, at 2: Then, with the multimeter set to continuity test mode, check which pin is now connected to the normally open NO pin in this moment.
What is Web Browser. 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 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.
Activation voltage of the relay during this demonstration. Relay is an electromagnetic device which is used to isolate two circuits electrically and connect them magnetically.
Identify Terminal Pins of A Relay Without Reference to Datasheet – Tutorial by Cytron
Then, connect the output terminal of DC power supply across the coil pins of the relay using crocodile clips. Since the common pin is determined, thus another one remaining pin in the connected pins detected in step 3 must datssheet the normally closed NC pin.
Does Icc needs more current for 4-channel? Set your multimeter to continuity test mode.
Thus, the other hrs4h-s-dc1v remaining pins in the connected pins must be common pins. May 11, at 5: This is really useful for me to understand how to identify a relay.
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. Choosing Motor For Robots.
Nov 29, at 3: Relay have become a common use electronic component which operate as an switching device by simply apply voltage to ON and OFF it.
Thank you Suan Kian, thank you Cytron, excellent tutorial, daasheet website. So, i connected them to Arduino UNO pins and only 1 relay worked.
(PDF) HRS4H-S-DC12V Datasheet download
Based on this finding, the remaining pins must be normally open NO pins. Oct 23, at 6: Leave a comment Cancel reply. For this project, we will discover a simple relay connected with an LED to show what is the basic function and connection.
Get inner details about structure of a relay switch. Jan 31, at 2: Feb 10, at Choosing Battery for Robots. Aug 28, at Jan 28, at 8: There is only 3 remaining pins to determine which are the NC pin, NO pin and common pin. Now, all the pins of relay have been determined as shown in Figure 16 below.
