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.

Amazon Inspire Digital Educational Resources. Pages with related products. ComiXology Thousands of Digital Comics. Before we proceed with the circuit to drive the relay we have to consider two important parameter of the relay. Amazon Rapids Fun stories for kids on the go.

This switch can be anything from a small transistor to a microcontroller or a microprocessor which can perform switching operating. I would like everything to work on one power supply. 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 Customers also shopped for.

Welcome to the “controller” blog: JQC-3FC(T73) DC12V pinouts

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 jqc-3vc a Ohm resistor.


You can also notice a diode connected across the coil of the relay, this diode is called the Fly back Diode. Our relay here has 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.

The above circuit shows a bare-minimum concept for a relay to operate. Hi, I have a relay jqc-3f, for example, I need to using Arduino, enable or disable the propeller to operate from AC V.

If connected to NO the load remains disconnected before trigger. Read times previous topic – next topic. Just need to find a relay with 5 volts. Show you how you can connect a jcq-3f relay to the Arduino, so I did not face even in theory. Get to Know Us. Amazon Renewed Refurbished products with a warranty.
