DC 5V-36V Timer Module Cycle Delay Timer Switch Turn On/Off Relay Module with LED Display

Three years ago I bought two of these devices to control the timing of a plant watering system. I use a regular 7 day AC timer to set watering times, then the timer to control cycling of water pump. I used mode 3.2 which without trigger is to energize (OP mode), then deenergize(CL mode), then repeat LOP times. This has worked fine for over 3 years. Just recently I started setting up the second unit purchased in same order. I found it starts in the CL mode, then the OP mode, and then cycles LOP times. I could find no way to get both units to operate in the same manner. For my application, this is not a problem, but someone needing one of the OP -> CL cycles (vs CL -> OP) will find the timer doesn't function as described. Great little device, I hope someone has found a hidden setting that would make both devices operate identically. (I experimented with trigger input as well - no effect in this mode) UPDATE: I found doing a "long press" of the UP button toggled the OP->CL or CL->OP sequence. The display flashes F1 or F2 briefly to show the mode, but you need to keep track which "F" you are setting as doing a long press on DOWN toggles a different F1 & F2. This state controls whether OP=on and CL=off, or OP=off and CL=on. Yes this is confusing but it got my timer back to as expected. I bought another timer that has operating modes P0 to P9 and these two UP and DOWN toggles were not available. I suspect this product continues to mature. A bit of a challenge to figure out all the possibilities with these timers but pretty slick when you do.

The positive terminals will always be hot. This item only turns ON or OFF the NEGATIVE terminal. It has many useful settings, but you will need to go online or read through the other reviews for instructions.

This switch was to be used on my pinball machine. I’ve added a roll over switch and a toy connected to a 12 volt motor. It works, but it runs all the time. This switch was to solve that. The ball hits the roll over switch and the motor will run and move the toy for 5 seconds. Unfortunately, I never got that far. I was excited when the switch was delivered only to be very disappointed upon opening up the package. Inside the UPS bag was a small plastic bag with the switch and a smaller plastic bag inside the first bag. That smaller bag wasn’t sealed closed. It was a used bag. It had been cut open and left that way. Inside was the timer module for the switch. This is supposed to already be soldered to the switch - and it had been, but it was broken off. Instead of repairing it, someone just shoved the module in a bag, stuffed that bag and the switch into a bigger bag and sealed it. Then they sold it and I was the lucky buyer. Even though I am rightfully angry that someone would intentionally sell a broken item as if it were new and in working condition, if I thought I could repair it I might keep it. Sometimes things break, nothing is perfect, but this time someone had broken the module off and still intentionally repackaged the switch for sale as new. Unacceptable! Now I had to order a different switch, miss the Prime Day pricing and wait for it to be shipped. Arrrgh!! I've already arranged to return this broken item for a refund and I ordered a different switch from a different seller. Oh, the switch came with no instructions, but that would have been okay since it was clear to me how to wire it up. Of course, neither were there instructions on how to reattach that broken off module. I would have had to use the broken solder marks to figure out it’s orientation. - but I won’t be doing that. In the picture you can see where the module broke off of the board. There is solder on the board and solder on the module legs. That bag is what the module was shoved in to. Not the switch. The switch and the bag with the module were placed back into the bigger bag to be sold to some poor lazy schmuck that would think it too much trouble to go to the trouble of returning such a low cost item. I was the wrong guy. I'm retired, have all the time in the world and I'd go to the trouble of getting my money back if it was less than a dollar. Think of it as an old fart's tenacious hobby. Beware! I have no doubt that once they receive this broken switch back that they will repackage it and try and sell it again - probably to you.

Works as intended but it is missing the instructions. Here is what I found on another site. 0.1 seconds (min) to 999 minutes (max) continuously adjustable. This product is easy to use, many functions, but all buyers need to carefully read the instructions, very useful product. Module characteristics and uses: To achieve fast turn-on and off the circuit, an unlimited number of switching; Conducting and cutting process does not produce noise, no spark, no electromagnetic interference; Compared with electromagnetic relay products, longer life; The dual-MOS parallel drive, lower resistance, more current, strong power; at room temperature, operating current of up to 15A, power up to 400W, to meet the most use of the equipment; A method for controlling the motor, lights, LED, DC motors, micro-pumps, solenoid valves, etc., very convenient.

Increase the sleep mode, if this mode is enabled, without any operation within 5 minutes, then automatically turn off the monitor, any key wake-up; You can set a different OP, CL, LOP parameters, which are independent of each other, and are automatically saved; After the module is powered down, all parameter settings are not lost. Operating mode: P1: trigger signal, the relay is on "OP" time, and then disconnect; in the "OP" time, as follows: P1.1: signal is triggered again, invalid P1.2: signal is triggered again, the clock is reset P1.3: Signal trigger again, relay off, stop the clock; P-2: trigger signal, the relay off "CL" of time, the relay on "OP" time, and then disconnect relay; P3.1: trigger signal, the relay is turned on after the "OP" time, the relay off "CL" time, then the operation cycle, if the trigger signal period, the relay off, stop the clock; the number of cycles ( "LOP ") can be set. P3.2: without triggering signal, the relay is on "OP" time, the relay off "CL" time, and has been cycling; frequency ( "LOP") cycle can be set; P-4: signal holding function. If there is a trigger signal timing is cleared, the relay remains on; when the signal disappears, after the timing "OP" time, the relay is; if another signal during timing, timing is cleared; Product parameters: 1: Operating voltage: 5--36V. 2: Trigger Source: Active-high (3.0V-24V), have optocoupler isolation, can improve the system's anti-jamming capability (customers can also shorting common ground). 3: Output capacity: DC 5V - 36V, at room temperature, continuous current 15A, power 400W!

Pay attention: The module is an active output, the output voltage equal to the input voltage. 2.'DC + 'and' load + 'This is an internal short circuit of the poles, but' DC- 'and' load - 'poles during use can not be shorted, otherwise the load can not be controlled on and off, which is equivalent load is been carrying electricity. Timing range 0.1 seconds (min) to 999 minutes (max) continuously adjustable How to choose the time range? After setting the mode selection screen parameter value by a short press "STOP" button to select the time range; XXX. decimal point in the unit place, time range: 1 second to 999 seconds. X decimal point in decade place, Timing range: 0.1 seconds to 99.9 seconds X. X. decimal full brightness, Timing range: 1 minute to 999 minutes. For example, you want to set "OP" is 3.2 seconds, then move the decimal point to decade place, the digital display 03.2 Parameter description: "OP" - conduction time, "CL" - off time, "LOP" - the number of cycles (1-999 times, "---" represents infinite loop). These parameters are independent of each other, but is shared by each mode. For example, in P1.1 mode, set the on-time "OP" is 5 seconds, if you switch to P1.2 mode, it's "OP" will be 5 seconds too. In the main interface (display 000), short press "SET" button will display "OP" ( "CL", "LOP") and the corresponding time XXX; Some parameters only mode "OP" (such as the mode P1.1, P1.2, P1.3), short press the "SET" key to display only the "OP" and the corresponding time; Some models have parameters "OP", "CL", "LOP" (such as the mode P3.1, P3.2), short press "SET" button will display "OP" and the corresponding time, "CL" and the corresponding time, "LOP" and the corresponding number of times; In the main interface by short press "SET" key to see information about the parameters of the current mode, very convenient! How to set parameters? First, read the instructions to determine the required operating mode. The module is powered up, the display at the current work mode (P1.1 default mode), then enter the main interface; press "SET" button for 2 seconds after release to enter mode selection interface; a short time by pressing "UP", "DOWN" key to select the mode (P1.1 ~ P-4). Select the mode (such as P3.2), short press the "SET" button, then the parameter to be set flashes ( "OP" on-time, "CL" off time, "LOP" cycles ( "---" represents infinite loop)), by "UP", "DOWN" keys to adjust the parameter value, support long press (rapid increase or decrease) and short press (increase or decrease one unit); then short press the "STOP" key to select the decimal point position, select the time range (0.1 seconds to 999 minutes); short press the "sET" button to set the next parameters of the current mode of procedure is as above. After the parameters are set, long press "SET" button for 2 seconds then release, the name of the current mode will flash once, and then return to the main screen, set the parameters of success! The main interface: In the relay does not work status display "000" (no decimal point), with a decimal point under relay state. Mode selection screen: Long press the "SET" key to enter, after setting is completed, long press the "SET" key to exit back to the main screen. "STOP" button extensions: Relays enable mode: ON: Relay allows conduction in the "OP" on-time; OFF: relay prohibit conduction is always closed; In the main interface, short press the "STOP" button to switch between ON and OFF, the current in which the state will flash, and then return to the main screen. (This feature is an emergency stop function, click off the relay) Sleep mode: "C-P" Sleep mode: five minutes without any operation, the digital display automatically turns off, the program running as usual; "O-d" normal mode: digital display always open; Press the "STOP" button for two seconds and then release to switch "C-P" and "O-d" state, in which the current state of flashes and then return to the main screen.

Versatile little gizmo once you learn how to program. Mine arrived with no instructions and there's a plethora of online videos that can help. Unfortunately, Amazon won't let me post a link but I bet if you searched p9u8lrsRrWE you'd find the one I found most helpful. Note the instructions are for a different board but the programming instructions are identical.

I purchased this with the intentions of using it in an OpenAutoPro set up, as an accessory delay. When i tested the unit in a controlled environment using the setting, it worked as it should have (P4 for delayed shutdown after the trigger is removed). It timed out and shut off s it should, however when I installed the unit in my car, the unit did not shut down after the timeout. I tested this repeatedly in the car as well as back in the test enviroment. the unit seems to work fine on lower 12VDC sources (I was using a12V 5A barrel charger to test), but not so much in the car.

I use this in a very low power application where I need to conserve solar batter as much as possible. The sleep mode helps me do just that. I could not figure out how to shut the display off other than wait for the sleep mode to activate. Maybe I'm picky. Timer works and handles the current well.

This is a great compact unit. It took a while to figure out that the timed output DC +, DC -, must be wired up as a separate connection. Hooking up the DC - to the ground circuit, shorts out the unit and will turn on the output, DC +, continuously. I used DC +, DC -, to energize a relay and used the relay contacts to run my lights.

Hola buen día, llego a tiempo el equipo, y para el proyecto que necesito la función de tiempo de desconectar hasta ahorita está funcionando bien y sin ruido de los tradicionales relevadores. Saludos

This item actually has some relatively good instructions. Once I read them 10 times while the unit was powered up, I figured it out. I think these Chinese companies should hire someone from North American to write their instructions. We have a different way of processing information over here so it would be better to have someone here do the instructions. I might do a video on it when I get time. I’m using it to accept a signal from my invertercharger to start an auto start generator. The inverter cancels its start signal as soon as it gets input from the generator. This is only about a 2 minute time line so I connected this time to a relay that interrupts the signal to the generator to turn itself off for 25 minutes. This is enough time to charge up the batteries for another 3-4 hours. There was one glitch but I think it was because I didn’t have a diode across the relay terminals to knock down the high voltage spike when it disconnects. I’ll change the review if it keeps acting up.

Using to make generator remote starters and it works great as the start delay timer

tuve que investigar un poco en internet para encontrar un instrucctivo mas claro, para poder programarlo, funciona bien.

Práctico, confiable, barato,.. Me ahorré tiempo, dinero, esfuerzo..!!
