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.

PV charger battery circuit 4. Turn the relay upside down so that you are facing the pins not the plastic cover side, then it is easy to figure the pins since one side t37 three and the other side two.

What is the function of TR1 in this circuit 3. Thank you in advance!

please tell me the pin description of a 12v relay

Just need to find a relay with 5 volts. Dec 248: OK, so that is a series of relays available in different coil voltages, notably 5 V and 12 V.

I really don’t like that big brass thing exposed with 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 Sign up using Email and Password.

Hi, Jqc-3cf have a relay jqc-3f, for example, I need to using Arduino, enable or disable the propeller to operate from AC V.

Thank you, so clear, once again thank you for your help! Home Questions Tags Users Unanswered. Equating complex number interms of the other 6. Synthesized tuning, Part 2: No, don’t apologise, but if you want sensible answers, post a Web link to the thing you are talking about. Hi, I have a relay jqc-3f, for example, I need to using Arduino, enable or disable the propeller to operate from AC V.

The relay will drive the pump as shown in the picture. 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.

Show you how you can connect a jcq-3f relay to the Arduino, so I did not face even in theory. 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.

The 5 V relay would require 80 mA to operate, while the 12 V would require 30 mA. Read times previous topic – next topic. Please tell me in that way which pin connected where. Link up manifnst of the relay.

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.

Anyone know the IR remote TV pin description???
