DROK 12 Volt Timer Relay 2pcs, 0.1s to 999min 50mA 4-Mode On-Off Automotive Digital Delay Relay, Electric Delay Timer Switch, Cycle Time Delay Module with LED Display

Installed this relay to P1 function on an automotive application to prime the fuel pump. It works flawlessly and I can increase or decrease the prime time on tje fly.Unit seems to be well constructed but it's not waterproof so I have it reside inside the cabI also have another one to open the garage door with flashing the high beam 😀

The device works fantastically.. the settings took some getting used to.. but we’re fairly easy to fumble around.. I did make a hardware change as I’m using this as an ignition timer, when the vehicle turns off, this thing continues you put out an “ignition” signal for an additional 3 mins.. this “ignition signal drives a 60 amp relay, thus hard cutting power to all my devices..only problem was this guy remains on so I made a small hardware change to have it cut it’s own power.. by using a diode connected from ign to +in and + in connected to the output(NO of relay) when I apply battery + voltage to the common of the relay and normal ground.. the ignition source will trip the device and turn it on and when on its relay trips into the NO position.. this keeps the relay on.. until the ignition is released, and it starts timing down. After it is done the device is no longer receiving power and thus not bleeding the batteries..

Used it as a timer to trigger a front camera on my truck for 10 seconds when put into drive. Works great and retains its memory when power to the unit is cut off.

The instructions for this are hot garbage, to the point that i want to return it because i dont think ill be able to get it to work the way i want it to. But im not sure because the instructions are so bad

I used this with a momentary switch to add downward facing lights to shine below my SUV tailgate when camping. It's perfect to quickly turn on the lights when I'm unloading or hooking up a trailer at night and I can just leave it to turn off automatically.

I added 12V trailer marker lights to my driveway's security gate so that I could back my truck out at night and clearly see the gate so that I didn't back into it. The gate controller provided the 12 volts required for the lights however when the gate was fully open or closed the lights would go out. I needed them to stay on another 30 seconds. This timer worked perfectly for that function.The instructions included with the timer are extremely poorly written. These companies should hire a person who fluently speaks English to write or at least proof read their gibberish. I couldn't get the timer to work as how I interpreted the instructions but tried different modes until I got it to work as I needed. I withheld 1 star based on the instructions.

I wanted my trucks stereo to stay on after I turned of the truck, 2004 RAM. I re-wired the stereo system to one fuse block located behind the radio and had it connected to a relay from the battery. This timer is wired to the relay so that after, 5 minutes for me (up to 999 seconds), the relay would shut off the stereo. Works perfectly. Now, I wouldn't truthful if I didn't also mention that for me, it took some time to figuring out to get the configuration correct. Depending on your ability, it can either be hard or easy. I'm no master electrician, so it should be doable for most people.

User interface may be logical but it is not at all intuitive. Combined with poor instructions it took me a few tries until I got used to it and got the correct program. Was tempted to crush it with a hammer a while but now it works fine and I am pleased with it

J'utilise la fonction F2 pour temporiser la coupure de mon faisceau infrarouge durant 3 secondes. Le but est d'eviter qu'un débrit, pousser par le vent, ne déclenche inutilement l'alarme. Le faisceau doit être coupé, de façon continue durant 3 secondes, pour enclencher le relai qui active l'alarme. Dans le cas contraire, la minuterie se replace à 3 secondes. La durée est ajustable. Très bien contruit et très fiable.

Instructions are unclear so needed to refer to youtube

Bought this to supplement my new Fusion stereo system on my boat, now the stereo and remotes will stay on when I turn the engine off when switching surfers. Seems to work well so far in mode P4, but as other have said, the instructions suck -- with good instructions it would have been a lot easier to install.
