Found this on the internet in 5 seconds or less. Its not % clear whether its a bottom view of the device or top side view of the socket, you can determine that in . A relay is an electrically operated switch. Many relays use an electromagnet to operate a switching mechanism, but other operating principles are also used. 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.

I would like everything to work on one power supply. Show you how you can connect a jcq-3f relay to the Arduino, hqc-3fc I did not face even in theory.

Relay jqc-3f, connect to the arduino. Hierarchical block is unconnected 3. Dec 242: Sign up or log in Sign up using Google. AF modulator in Transmitter what is the A?
I have read that if Arduino submit 12V, and they will be available at the outlet, do not want to burn the card check this out I apologize for my English.

Link up manifnst of the relay.
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 I agree – I would solder a wire to the relay and insulate with heat-shrink tubing, then put the other end of the wire in the brass thing, ideally located in a plastic box so that it can’t be touched. OK, so that is a series of relays available in different coil voltages, notably 5 V and 12 V.
PCB Relay JQC-3F(T73)
Measuring air gap of a magnetic core for home-wound inductors and flyback transformer 7. Anyone know the IR remote TV pin description??? 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 Note that the output of your relay at least as shown in the schematic is connected to the mains v so be very careful, don’t touch it while it is powered.
Show you how you can connect a jcq-3f relay to the Arduino, so I did not face even in jqc-3dc. The brass thing will be carrying v ac. It’s just not very convenient, because will have to make separate meals Please don’t make requests for help in private using PM. Thank you, so clear, once again thank you for your help!
Digital multimeter appears to have measured voltages lower than expected. Hi, I have a relay jqc-3f, for example, I need to using Arduino, enable or disable the propeller to operate from AC V. I have read that if Arduino submit 12V, and they will be available at the outlet, do not want to burn the card check this out Hope it solves your problem.
Is the wiring as shown in the picture a good idea? No, don’t apologise, but if you want sensible answers, post a Web link to the thing you are talking about. Dec 248: Jjqc-3fc reading this before posting: 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 jqc-3c need to power it, and the base supplied r73 an Arduino pin via a Ohm resistor.
Thank you in advance! You also need a diode across the relay coil, anode to the transistor collector and cathode to the supply.
