Features:
It is a timer relay module with high precision, stable and reliable performance.- Support 2 modes, mon mode(once) and cycle mode, and you can simply switch mode by adjusting the jumper.
- Connect 2 wires of "Key" if you need module to work recurrently after power on.
- There are many voltage and time range for your choice, both "on" time and "off" time are adjustable.
- Widely used on timer operating equipment, machine repetitive test circuit, fish tank intermittent pump, etc.

It's a 1-shot timer when triggered in Mon mode and cycles forever when triggered in Cycle mode.Triggering again the Cycle mode stops it until triggered again. Timing trim pots are finicky and full CW are the shortest times, fully CCW are the longest times.

I've uses several of these. One cycles a circulating fan in my RV fridge. Another probides a delayed of for lights. Sort of finicky to get desired timing.

If you are a hobbyist this inexpensive module is for you ! I made a bench test and found that the time control adjustments are backwards to what we are normally used to, turn it COUNTER CLOCK WISE to increase the time. Note that the shorting clips can change the timing from 120 minute to 12 minutes, and the other clip changes the cycling from on-off-on-off etc, to one shot on and off. I found the mounting holes too close to the input and output connectors, so I removed these connectors and soldered wires to them directly. I also used an old dc power module found on many electronics to power it up.

Doesn't work for what I wanted to use it for as the minimum time range was misleading. The description says 0-120min but realistically 0s doesn't make any sense and T/10 was super vague.I had to trial and error test it with a stop watch to find out the shortest time was 4min. If you max out the potentiometer that almost doubles to just under 8 minutes. If you want anything less than 4min try something else.I should also mention that the trigger button behavior is momentary and will switch between states.IE: press it and it'll turn on, press it again it'll turn off, regardless of the delay cycle. Probably what most people are expecting but for my project I really just needed the ON state only, subsequent presses shouldn't do anything until it turns off automatically.

i tried everything so did my electrical friend. the settings don't work, this is a scam.
