JQC-3FC(T73) DC12V pinouts. A relay is an electrically activated switch. It consists of a coil internally which will creates a magnetic field that. 1 Part number NT73(JQC-3FC). 2 Contact The use of any coil voltage less than the rated coil voltage will compromise the operation of the relay. and. A relay is an electrically operated switch. Many relays use an electromagnet to operate a switching mechanism, but other operating principles are also used.

Show you how you can connect a jcq-3f relay to the Relat, so I did not face even in theory. You can also notice a diode connected across the coil of the relay, this diode is called the Fly back Diode.

Withoutabox Submit to Film Festivals. Before we proceed with the circuit to drive the relay we have to consider two important parameter of the relay. Amazon Renewed Refurbished products with a warranty. Amazon Inspire Digital Educational Resources. You need a general-purpose NPN transistor with its emitter to ground, it collector switching one side of the relay coil with the other side going to whatever voltage you need to power it, and the base supplied from an Arduino pin via a Ohm resistor.


Thank you, so clear, once again thank you for your help!

OK, so that is a series of relays available in rellay coil voltages, notably 5 V and 12 V. Only 2 left in stock – order soon. This switch can be anything from a small transistor to a microcontroller or a microprocessor which can perform switching operating.

Thank you in advance! The relay plays the role as a protector or a circuit switch. Let us learn how to use one in our circuits based on the requirement of our project.

If connected to NO the load remains disconnected before trigger and jqc3fc connected to NC the load remains connected before trigger.


If connected to NO the load remains disconnected before trigger. Thank you very much for your reply, I will try to do so. I know that there are relay control modules, like DFRobot, but because of their high cost, would not like to use them because of the limited resource of the relay.
