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 have read that if Arduino submit jqqc-3fc, and they will be available at the outlet, do not want to burn the card check this out CMOS Technology file 1. No, don’t apologise, but if you want sensible answers, post a Web link to the thing you are talking about.

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

Turn on power triac – proposed circuit analysis 0. Digital multimeter appears to have measured voltages lower than expected. The wooden box will be used to contain the jq-3fc and ac lines.

Turn the relay upside down so that you are facing the pins not the jwc-3fc cover side, then it is easy to figure the pins since one side has three and the other side two. Thank you in advance! The relay will drive the pump as shown in the picture.

It’s just not very convenient, because will have to make separate meals PNP transistor not working 2.


PCB Relay – JQC-3F(T73)

It shows the two pins for the coil and the three pins that are connected to the switch Post added at It is clear that there is a version with two networks, one from Jac-3fc, 5V, jqc–3fc other for relay control, and which operate using 12V transistor OK, so that is a series of relays available in different coil voltages, notably 5 V and 12 V.

I apologize for my English. My relay has 5 pins,one side 3 pins and another side 2 pins. Read times previous topic – next topic. Wiring for power relay jqc-3fc t73 dc5v Ask Question. Just need to find a relay with 5 volts.

The brass thing will be carrying v ac. 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.

Link up manifnst of the relay. I would suggest you try the circuit either with a small low voltage lamp or with a led and a low voltage source until it is tested jqc-fc work properly, then if you want you can use a mains bulb.

Choosing IC with EN signal 2.

12V SPDT – 7A 250V AC PCB Type Relay

The time now is Just need to find a relay with 5 volts. Thank you, so clear, once again thank you for your help! Please don’t make requests for help in private using PM. Hope it solves your problem. Part and Inventory Search.

Thank you very much for your reply, I will try to do so. Post Your Answer Discard By clicking “Post Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and cookie policyand that your continued use of the website is subject to these policies.


I apologize for my English. Originally Posted by immadi. I would like everything to work on one power supply. 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.

Create a thread in the forum so that other members can benefit from the posted answers. Please help some one. The 5 V t3 would require 80 mA to operate, while the 12 V would require 30 mA. Please tell me the solution 3. OK, so that is a series of relays available in different coil voltages, notably 5 V and 12 V. Email Required, but never shown. Relay jqc-3f, connect to the arduino. I have read that if Arduino submit 12V, and they will jqc-3vc available at the outlet, do not want to burn the card check this out Considering that ac and DC need to be very close together on the pins?
