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.

The time now is That will have much safer connections on the AC side. Hi, I have a relay jqc-3f, for example, I need to using Arduino, enable or disable the propeller to operate from AC V. Thank you very much for your reply, I will try to do so. I really don’t like that big brass thing exposed with V. Read times previous topic – next topic. Part and Inventory Search. Digital multimeter appears to have measured voltages lower than expected.

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 suggest using one of the “Arduino” relay modules – a relay mounted on a small PC board with screw terminal blocks, and an optoisolator for the control input. No, don’t apologise, but if you want sensible answers, post a Web link to the thing you are talking about.

I apologize for my English. The brass thing will be carrying v ac. ModelSim – How to force a struct type written in SystemVerilog? Distorted Sine output from Transformer 8.

Relay jqc-3f, connect to the arduino.

Thank you, so clear, once again thank you for your help! I agree – I would solder a wire to the relay and insulate with heat-shrink jc-3fc, 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.

You also need a diode across the relay coil, anode to the transistor collector and cathode to the supply. Relay jqc-3f, connect to the arduino.

Please tell me the jqc-3fv 3.

I would like everything to work on one power supply. How do you get an MCU design to market quickly? 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.
