DROK® Multifunctional DC 12V 1 Channel Relay Board Single-channel Relay Module 10A Portable Timer Switch Board Power Switch Circuit with 18 Mode and LED Digital Display Cyclic Time Delay

Cute, well made little utility timer has 18 functions and works great. I only am using it for a latching function, but it is perfect.Have to visit website to view instructions, but they are thorough and concise. Sure a little choppy english but drill down and it makes sense. Simple programming. GOOD VALUE!

This timer is well built, looks amazing (if you like the electronic look), and functions well. The price is excellent for what it can do. My only problem, and other than this it would have been a 5 star review, is that there are no instructions with this device. They give a business card with their website, but can't even find this timer on the site. I used google to look for the model number's instructions and downloaded a pdf instruction manual. Also, the instructions are written in broken English, and some things are not descriptive enough, I had to play with the timer for a while to figure out what some of the features actually did. Overall a great timer, and now that I know how it works I would definitely buy another when needed.

How to use theres no paper work this is dumb, now can you send a product without user manual

I ordered two units. One of them failed. I can still hear the contractor making contact, but the power isn't flowing to the terminals

After googling the model number and finding poorly translated instructions on the functions and then finding a video on the wiring. I wired it into my truck to operate a power inverter that is powering battery chargers for power tools. I have it set to turn on with 12 volt key on, and once voltage is off to count down 60 minutes and turn off, ensuring any batteries I put on before I'm done for the day get a full charge for the next day.So -2 stars for no documentation.

What a great little piece of electronics. I’m impressed with its flexibility.Mine came with instructions but they kinda read like an old DOS computer manual.Sit down with a multimeter put it on circuit test and start playing. I’m using a 3 cell lipo as my power supply and a paper clip for activation (positive to CH1). Real professional, eh?Anyhow, hold the set button down for a couple of seconds and it’ll show you what mode (1-18) it’s in.SWI allows moving between the two right digits and in the timer selection mode allows to introduce a decimal for 1/10ths.Start on mode one, activate it see what happens. Cruise thru the modes until one comes up that works.

I love this thing. I use one to supply power to a dashcam for 2 hours after ignition cutoff for extra coverage without draining the battery. I use another to keep my reverse camera triggered a few seconds after I take it out of gear (manual) so I can still see the image if I’m rolling back.

The device arrived undamaged. I had it working in seconds. I searched the internet for instructions to operate the device. I have noticed that nearly all the instructions that come with these kinds of electronics are hilariously impossible to understand. Soooo, be prepared to push some buttons until you get the device to do what you want. For the price, there is great value in all the cool functions this timer will perform.
