FafeicyTime Delay Relay Module, 5v 12v 24v Cycle On Off Timer 50ma 0.01s-9999min Adjustable Trigger Delay Switch Control Board with LCD Display

I must admit I’m not a fan of stuff from China. It’s cheap because it’s cheap and nasty. This is no different inasmuch it’s cheap but I must give credit where it’s due. This is a low priced, quite complex little device which works well. Pity it doesn’t have instructions and relies on YouTube vids to work it out but once you get your head around it’s functionality it is a cool little gadget. The big test I guess will be how long it lasts so if it gives up the ghost soon then I’ll change my review to reflect that. However in the meantime it’s doing what I need it to - on a trigger event to turn on high power lights for a timed duration. It works 👍🤞

I have given timer 4 stars and would have given it 5 stars but there was zero paperwork or instructions provided with this unit. I have saved the detail saved on the amazon page for this product and used that for the instructions. One set up it works amazingly well. I used a 9v battery to power it and currently have it set to make contacts on relay for 20 secs every 20 minutes and it works a charm. So far excellent.

Used it to control my heated windscreen. Has a few different programs , take a little prodding to get used to it , like a 1980 digital watch. But works well . Would buy again .. only complaint would be I'd like bigger wire clamp terminals , to accommodate slightly bigger wires

Bought as a timer for a raspberry pi wildlife camera and worked fine. There were no instructions with it though - just the pictures in this listing - and setting the schedule was a bit fiddly. I found a youtube video showing the set up using an almost identical board which helped.

Nice but delicateMine arrived with the L1 inductor loose in the sealed bag and didn’t work. That inductor is very delicate and in a vulnerable position underneath the pcb.
