DROK Delay Relay Module, DC 6-30V Timer Relay 12V 24V 0.01s-9999min 50mA Digital Timer Cycle Delay Switch Module AC 220V Power On-Off Controller with LCD Display Switch Button Case

Works great for DIY induction annealer timer

Love this little delay relay. Has so many operating modes. I needed a device that could trigger off a negative signal when my car door is opened for a Siren. This device triggers off a negative or positive signal. I programmed the delay to be on for 5 mintues and is retriggerable. Perfect device and so inexpensive. Could not have found a better one and comes in a plastic case that is easy to mount.

Works well, easy to use. I combined this with a the Drok signal generator. This timer controls the output of the signal generator to provide a timer controlled signal of a programmable frequency. I only wish it would also allow it to be set as number of hours. Currently the maximum setting is 9,999 minutes which is only 166.65 hours. A minor issue, otherwise it is perfect for my needs!

As others have said the instructions leave a lot to be desired but I can at least share my experience with it. I have an el34 tube amp in may garage that puts out some serious wattage. It’s hooked up to an aiyima t8 Bluetooth/ preamp. When the aiyima shuts down it sends a decent spike to the amp and speakers making a loud speaker destroying pop. I have everything hooked up to a smart plug so everything shuts off at the same time. This isn’t a problem with solid state as much because solid state is on or off unless they have some crazy capacitance. Tube stuff doesn’t shut right down since the tubes are still hot and flowing whatever is left in the capacitors. What I needed was something that would delay the preamp shutdown until the tube amp is completely powered down. There are 9 modes on this thing. What are they? I have no clue the instructions are very poorly translated but you can kind of guess. I can really only speak for mode 8. Mode 8 starts a shutdown timer when voltage is lost at the signal input which is inside the timer box. I’m using a usb power supply for the trigger which would be considered a high signal. So I have it set to mode 8 at 20 seconds. When the usb looses power (connected to the same switch) the timer starts counting down and then opens the relay for the 12v (plugged into constant power) that sends power to the preamp. It works as it should. A few notes. The instructions say when it displays “out” that the relay is open. This is the opposite, the relay is closed when “out” is displayed. There are 2 options for relay status, CL and OP. I believe they mean close and open but I don’t know if they mean normally open or open after the trigger is there. You can change where the decimal point is for the timer by holding one of the buttons which makes it more confusing. There is also no plug for the trigger connections but I found something that worked you could also solder to the pins. I found that reading the instructions to the best of my ability and experimenting worked the best but

Not too easy to understand how to set up, but after that, works flawless. It keeps the setup even without power, its really good that feature

I love most DROX products. I’m using a XY-WJ01 Digital timer. It’s working well, but I have a strange effect. I’m using the timer in Mode P6 with OP:600, CL1,LOP:1 . I’m tryign to get the relay to tunr on at power on, stay on for 600 seconds (10 minutes). then turn off, and not repeat until the power is disconnected and reconnected. Most of the time it works perfectly. , I’m seeing that the relay closes correctly at power up , and stays closed for 600 seconds, as desired, The relay then opens.. . usually the relay stays open until the power is disconnected. Sometimes though, after turning off, the timer mysteriously restarts after approximately 10 minutes as if the power had been disconnected and reconnected, though the power has remained on. What could be causing this false triggering ? Do I have the parameters incorrect ? I think they are correct, because most of the time it works exactly as intended. The re-triggering happens only sometimes. I’d appreciate any help ! Thanks ! -jc

First, Thank you to all that responded to my question. We have a garden train display at a Nursery that runs for 5 months on a push button. This unit I been testing for a day looks to be the replacement of 3 boards in one. One more day of testing then install. Again Thank you. Set up was good for me. Will be stocking up on more of these. The one I purchased was rated for 10 dc amps.

Piece of Junk. Dies in less than a year, was not very accurate. Spend the extra money on something else if you want accurate readings.

Works good

Works well.

I bought this timer for anealing my cartridge shells. The timer is connected to my anealer and times all of my anealing at 5 sec each. You can program it to the amount of seconds or minutes that you want. Very handy.

Works as advertised, just hope it lasts a long time….

Use on an induction heater to anneal shell casings. Bought 2 incase I needed a backup...it is gathering dust in the back of our reloading room. I would say approximately 8000 rounds. Simple to use for an old guy like me.
