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.

I apologize for my English. Thank you, so clear, once again thank you for your help!

There’s a problem loading this menu right now. The other end of the load is either connected to NO or NC. Hi, I have a relay jqc-3f, for example, I need to using Arduino, enable or disable the propeller to operate from AC V. Well, 80 mA is far too much for an Arduino pin to source 20 mA practical maximum and 12 V is too much for it to switch in any case.

Submitted by admin on 26 September It is clear that there is a version with two networks, one from Arduino, 5V, 12V other for relay control, and which operate using 12V transistor Before we proceed with the circuit to drive the relay we have to consider two important parameter of the relay.


Thank you very much for your reply, I will try to do so. Amazon Music Stream millions of songs.

Product features Product name: Be the first to review this item Amazon Best Sellers Rank: I would like everything to work on one power supply. TL — Programmable Reference Voltage. Amazon Inspire Digital Educational Resources. This jqc-3vc can be anything from a small transistor to a microcontroller or a microprocessor which can perform switching operating.

You eelay 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. See more product details. Don’t see what you’re looking for? Please make sure that you are posting in the form of a question.

Relay jqc-3f, connect to the arduino.

Get to Know Us. Amazon Restaurants Food delivery from local restaurants. The purpose of the diode is to protect the switch from high voltage spike that can produced by the relay coil. You can also notice a diode connected across the coil of the relay, this diode is called the Fly back Diode.

Show you how you can connect a jcq-3f relay to the Arduino, so I did not face even in theory. Our relay here rela 5V trigger voltage, but you can also find relays of values 3V, 6V and even 12V so select one based on the available voltage in your project.

If connected to NO the load remains disconnected before trigger.

It can protect your electric equipment’s very well. Learn more about Amazon Prime. Alexa Actionable Analytics for the Web. Share Facebook Twitter Pinterest. Would you like to tell us about a lower price? OK, so that is a series of relays available in different coil voltages, notably 5 V and 12 V. Customers who bought this item also bought. Thank you in advance! Get fast, free shipping with Amazon Prime. The 5 V relay would require 80 mA to operate, while the 12 V would require 30 mA.

Common is connected to one End of the Load that is to be controlled. Amazon Rapids Fun stories for kids on the go. You also need a diode across the relay coil, anode to the transistor collector and cathode to the supply.
