Wow, wow, wow. Any questions people would have you have answered. Excellent video, thank you good sir !

I was frustrated with potentiometer. Adjusting it tiny bit by bit...I am happy now to know i need to turn it 10 + times:D thank you!

[FSXgta]

Thank you for explaining how to connect it, I will use it for my car amplifier. In the winter I don't want it to turn on and draw power until my car is started

I have just changed the variable resister for 5meg ohm and the big capacitor from 100 to 1000uf can now get well over half an hour time which is what I needed.

[rickneill]

Good and thorough explanation including safety issues. 👍👍 ✔️✔️

3:50 the relay might support 1.8KW but nothing connected to it on that circuit board looks like it could.

[MohammedRiad]

You can increase the time by changing the Capacitor to more farads. Delay time formula: T = 1.1RC. For example: Capacitor 22uf resistance 1M T = 1.1 * 0.000010 * = 10 seconds.

The input coil voltage is nominal rated on 12VDC, but whats the maximum input voltage the coil can handle? is this the same as the maximum output voltage?

[mozzarellaczy]

Hi, do u use an extra suply for the lamp or the delay transfor mthe 12v in 230v by the relay?

[squidlings]

Huge thx. I'm a novice so this really helped! 🙏

[dylanoracle]

Can I connect the relay timer to DC loads?

[jgprojects]

How can I use it as timer circuit,
I need relay to work for preset value, other wise close

[QuickMind]

would something like this be apple to operate a dpdt relay that reverses polarity on a motor and without big voltage drain when the car is off? I suspect a capacitor would be involved so that when the car coes off, the relay reverses polarity on the motor to operate for 2 seconds

Very good video kindly I ask you if can modifying to be power on instead power off best regards

[FF]

Very good demo. Can the timer be initiated with just a single short press push of a button switch, or does the control power need to remain applied during the timer period.?

[towmanal]

Nice video.i have a adjustable timer similar to this but no real directions for it.just a very vague diagram.i was wondering if you could tell me how to wire it if I sent you a picture of the diagram I have?

[Bodragon]

(0:25) - You say that the relay there can be used for an AC or DC load.
No. You are wrong.
Although DC can be used to energize the switching solenoid inside the relay, the actual load ratings for the various voltages that can be switched, (and which is printed on the side of the relay itself), are: 10A @ 250VAC or 15A @ 125VAC .
Nowhere is DC as a load even mentioned.

Can we combine it with wireless relay switch remote 433 mhz as a trigger?

[FuyangLiu]

Thanks for the video. One question: I have 24DC source, is there a way to still use this module or is there 24V version of this module as well? Thank you :)

[sriharshaveldi]

Thank you sir, your video helped me lot...
