Above is relay I’m using and everything works as expected using diagram below. I understand such a question can sound silly for electrical engineer, but I’m software engineer venturing in electrical world and need some guidance.
I am interpreting the datasheey of the printed circuit board of the relay module with accompanying notes as follows:. No large currents here, dataseet to worry. This voltage is consistent with the operating voltage on the relay”.
From the trace on the board it would seem that the middle resistor 1 kOhm is attached to the “IN” pin serving exactly this purpose. You could easily check this with an Ohmmeter or following the traces on the board.

Using single 5V relay jqc-3ff-s-z – safety advice required Ask Question.
Do I need to add anything else for relay to work safely and reliably? I know people recommend having resistor and transistor on IN line too, but are jqc-3gf necessary in this particular type of relay?
Moreover, it even looks like relay board has diode already above VCC terminalso I wouldn’t need extra diode on IN line? I am interpreting the picture of the printed circuit board of the relay module with accompanying notes as follows: I’ve tested components on board and can confirm it has: Thank you very much for your answer, I hope this topic will be helpful for others too.

I’ll already tested wiring and relay using LED before posting. Thank you for datazheet answer. As Ghanima was a bit more explicit I’ve marked his answer as accepted.
