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

Après avoir compris toutes les configurations possible ce Time Delay fonctionne parfaitement...

I used this relay as a timer on Lionel train display. My gateman is hooked up to a short piece of track, so he would toggle in/out in between the trucks of the cars. I used this relay with 0.7s delay using the P1.2 mode, so that it would trigger when the first car went by and reset the timer as the remaining cars went by. Worked perfectly. Now my gateman comes out when the first car comes by and stays out until the last one passed by. Very happy with this purchase.Programming:A bit awkward, but it works. I had to read the manual a couple times to get the programming of the time correct. Overall though, there are a lot of options, this is an extremely flexible design. My only gripe is that the instructions are not printed. In case this listing is ever removed, I saved the instructions in a text document.Power:For power, I hooked the 18VAC from the train accessory into a KBP310 bridge rectifier, which yielded 15VDC. I then added a 470uF capacitor. Note, if the capacitance it too low, the unit will not power up.Trigger:I ran the 18VAC train accessory power into the "Trigger" input. I ran the ground trigger from the track to the "GND_t" input. No optocoupler needed. Nice. On the output, I ran track ground into the COM and the NO (normally open) output to the gateman. So when the unit is triggered, the relay will close, the gateman will be grounded, and the gateman will come out (assuming you hook up power to the side of the gateman).

Funciona bien

As other buyers have already said, this is a great little device but it is challenging to learn. The instructions could be clearer but once you learn what they are trying to say you find it is a fantastic device. It retains memory after being powered off and that is very important.Unfortunately I needed this device in a hurry for a Halloween prop and I was not able to learn the programming in time so I had to do without. After Halloween I was able to sit down at my work bench and do like everyone else said and tinker with the options. Having the flexibility of full minutes or decimals of a second is very useful but it adds a layer of complexity. It is not worded well how this works, in the instructions they say to press the stop button to rotate between xxx, x.xx or x.x.x. It took me awhile to realize that when I press the stop button it doesn't show xxx, x.xx etc. it shows my number (60 seconds) as 060,0.60,0.6.6.0, etc. It was a "duh" moment for me.Also, figuring out the wiring if you wish to have a start stop button could be better explained. Thankfully one of the previous users posted a photo and I was able to see how they did it. I'm a visual learner so something a drawing or schematic would better server than their broken English explanation. You ultimately need to run a jumper from your power inputs to the start stop terminals, then your button will complete the circuit. My suggestion would be for the circuit board to have a separate tap specifically for start/stop.Overall very good to use once you learn it, opportunity for a V2 for sure. This will be my new standard for timers now. Away with the old potentiometer adjustment style where you don't know if you are making the delay longer or shorter.Oh, very well made circuit board too.

I have a bunch of animated Halloween decorations with the dreaded sound sensors that don't work for 💩 I wire the Try Me plugs into the relay and set them up to trigger them every minute or so. I use the P3.2 settings for this purpose. The programming instructions are in the product description.
