Customers have mixed opinions about the functionality of the relay. Some mention it works great once they watch the programming instructions on YouTube, while others say two out of three didn't work. The relay contacts didn't transfer, and they were unable to do basic functions like on delay, off delay, or other simple timer features.

Super versatile timer/relay board. Can be powered by 5-30V DC or microUSB
4 out of 5 stars
Super versatile timer/relay board. Can be powered by 5-30V DC or microUSB
Really great little timer/Relay board but instructions could have been clearer. Important things to know:1. It is powered by EITHER 5V micro-USB OR the 6.0-30V pin of the terminal block NOT BOTH.2. solder the gnd and gnd_t pins together if your trigger voltage is tied to the same gnd as your power supply. This is an AWESOME feature if your trigger signal can't be reference from your supply voltage.3. All of the triggers modes I tested (P1.1-4) required a "rising edge" voltage transition to trigger. IE: 0 volts to 10V etc.). There may be a way to trigger on falling edge but I didn't need it.4. NOTE: if you are running at a higher supply voltage (>>6V) you will notice the board will get warm/hot. That is normal as the circled device (linear voltage regulator) will be dissipating up to 2+Watts ((Voltagein-5)/.1A) while the relay is energized. In my use I was powered by 24V so for me I measured .1A while the relay was energized hence: (24-5)/.1=1.9W . tricks can be used to dissipate power elsewhere (series power resistor feeding the 6-30V power input but that will get hot as well).5. The MOST useful mode I found was mode P4 which turned the trigger into a level trigger which energized the relay as soon a trigger voltage was present. the counter started counting down once the trigger voltage was removed but the relay stayed energized until the the counter counted down to 0. VERY USEFUL AND VERY FLEXIBLE!!I used it control a sump pump which the trigger voltage coming from a float switch that control be a be unstable.

5.0 out of 5 stars Lionel Train Relay
Reviewed in the United States on May 28, 2024
Verified Purchase
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).

5.0 out of 5 stars Great device, challenging to learn
Reviewed in the United States on November 6, 2023
Verified Purchase
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.

5.0 out of 5 stars i'm impressed - if only there was a manual enclosed.
Reviewed in the United States on January 22, 2023
Verified Purchase
I like this timer, it seems usable for many situations, many probably past my needs. Some uses I might just invent for the fun of it. The only thing I miss is a good manual explaining the programs in plain English. So I wrote my own:

* Press the set button for a few seconds to then use the up/down buttons to select the program you need. Press the set button shortly to cycle to the various OP(en) and CL(ose) timers and LO(O)P counter. OP(en) timers can be programmed in increments of a second, CL(osed) timers can be programmed in increments of 1/10th of a second.
* The trigger circuit (Trigger and GND_T connectors) is galvanically separated from all circuitry by means of an opto-coupler wih a 2.2K resistor in series. While the board needs at least 6V, the trigger is activated with voltages as low as 1.5V over the Trigger and GND-T pins.
* WARNING: Although the relay states it can handle up to 250V the circuit board is not designed well enough to safely handle anything above maybe 48V. (It is missing it's air gaps to make it safe.)

Abbreviations used in display:
P -> Program
OP -> Open - no power to relay
CL -> Close - relay is powered
LOP -> Loop - number of cycles turning off and on before staying off.

Abbreviations used on board
COM -> Common wire - put power to this wire to then put your load/device on NC or NO.
NC -> Normally Closed - when the relay is not powered this contact is closed.
NO -> Normally Closed - when the relay is not powered this contact is open.

Available programs
P1.1: Run once for CL seconds after power has been applied to trigger.
P1.2: Run for CL seconds each time power has been applied to trigger.
P1.3: As 1.2 but turn off when power is re-applied to trigger within the countdown time.
P1.4: Run once for CL seconds but there is no power to trigger needed.
P2.1: After applying power to the trigger delay for OP seconds, then run for CL seconds.
P2.2: After applying or removing power to the trigger delay for OP seconds, then run for CL seconds.
P3.1: Cycle on and off for OP and CL seconds and LOP cycles when power to trigger is applied momentarily or permanently, restart cycle in "on" phase when power to trigger is re-applied during "off" phase, stop cycle when power to trigger is re-applied in "on" phase.
P3.2: Cycle on and off for OP and CL seconds for LOP cycles without the need to put power to the trigger.
P4 : Run when power is put to trigger and continue for CL seconds after power has been removed from trigger.

Note
* The 5v USB connector can be used for programming/exploring but most programs won't run as the trigger port can't be self-powered by the board's 6.0~30V input. However, and I have not tried this, but I believe that if you bridge diode D2 and voltage regulator U3 you can have a complete 5V 500mA project going from a standard 5V USB cable.

Handy little circuit, once you figure out how to set it up. Thankfully there is a video out there somebody made. Only issue I have is the terminal blocks. So difficult to connect anything, they don't expand much, and are hard to tighten to the wires unless you are using a single solid core wire.
