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 picture of the printed circuit board of the relay module with accompanying notes as follows:. No large currents here, nothing 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 jqc-3cf the “IN” pin serving exactly this purpose.

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 these necessary in this particular type of relay? Moreover, it even looks like relay board has diode already above VCC terminalso I wouldn’t jqd-3ff 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 the answer. As Ghanima was a bit more explicit I’ve marked his answer as accepted. Sign up or log in Sign up using Google. Sign up using Facebook.
