[2 Pack] DC 6-30V Timer Relay Programmable Delay Relay Module Cycle Timer with LED Display / 5V Micro USB, Smart Home Controller

few mins too get my head round the settings but works well once i sorted how to programme it

The only instructions supplied are those on the Amazon website. They are just clear enough to be followed, but not great. Once they’re understood, the product works well, at least on day one and for the modes I’ve tried out.

Very happy with purchase

No stars for these I’m afraid.Ordered two of these and both were faulty, and I had to return them for a refund.First one was DOA no display and began to overheat in a short timeThe second one had a display but it all failed whilst trying to programme it.I also noticed that they wasn’t identical units.Anyway I re ordered another two different units from Amazon that had a lcd display instead of the digital led display.These were great both worked straight away and were so much easier to programme and also easy tocheck the programming, you have to look up on y tube for instructions but I’m really impressed with these replacements.

Well made good product; easy to use and set up. No instructions sent with product so need to copy/print that given in the Amazon listing.... only minor downside

The unit does exactly what I wanted. The instructions English translation from Chinese is challenging.The relay and terminals are soldered on the front and not on the back making it impossible to mount on a facia panel. I un-soldered the relay and terminals and refitted them on the back. Now it's easy to mount on a facia panel.

used on a door access system for door held open alarm .. works well and great price

Unlike another identical looking one I bought first (branded "ARCELI"), these ones do work correctly. They remember their settings when the power is cut, the display can be set to switch off and the timer works properly (the ARCELI one ran at double speed!).However I found that the module itself uses a bit more power than specified, which is a problem for me because it's for a battery powered application and I'd rather not waste any more power than necessary. At 12V the current draw in standby was almost double the 20ma specified. So I sent them back and I'm trying a slightly different one that uses MOSFETs to switch the power instead (they seem to be better so far) and these are being returned.The power consumption might vary with a different supply voltage but given that it doesn't specify at what supply voltage you should expect 20ma current draw in standby the only way to tell was to test it myself.None of this will be a problem if it's not being run from a battery and apart from that they work really well. The MOSFET version is only for low voltage/power stuff so these relay ones definitely have a place because they can switch a different voltage, including mains, which is isolated from the module's power supply by the relay.
