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.

Thank you very much for your reply, I will try to do so.

The transistor drives the relay control coil coil1 and coil2 pins I don’t see the problem. 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.

Considering that ac and DC need to be very close together on the pins? AF modulator in Transmitter what is the A? Turn the relay upside t3 so that you are facing the pins not the plastic cover side, then it is easy to figure the pins since one side has three and the other side two.

Just need to find a relay with 5 volts. 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. Thank you in advance! I would like everything to work on one power supply. Relay jqc-3f, connect to the arduino.

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

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. The time now is Link up manifnst of the relay. Part and Inventory Search. Input port and input output port declaration in top module 2.

please tell me the pin description of a 12v relay

Anyone know the IR remote TV pin description??? Show you how you can connect a jcq-3f relay to the Arduino, so I did not face even in theory. You also need a diode across the relay coil, anode to the transistor collector and cathode to the supply. Hi, I have a relay jqc-3f, for example, I need to jqc-f3c Arduino, enable or disable the propeller to operate from AC V.

12V SPDT – 7A 250V AC PCB Type Relay

That will have much safer connections on the AC side. What is the function of TR1 in this circuit 3.
