Equipping a home or office with cool, custom Electronics is always a fun time, especially if those electronics are going to make your life easier, more comfortable or more convenient in one or many different ways. However, if there’s one thing that always seems to make projects even better than they ever could have been, it’s automation, and the ability to act or react according to very specific variables, so that you never even have to think of them, and can instead just rely on the automation to handle all of the parts of life that previously had to be done manually, and this is why we love fancy little Modules like this 24H 5V Timer Relay.

This seemingly simple but surprisingly complex Relay Module is capable of controlling circuits up to 10A/28VDC, making it a great choice for all kinds of applications, and features a range of built-in timing-based features for enhanced automation functionality. These features are all designed to make your life more automated, more convenient and overall more enjoyable, ensuring that you can “Set and Forget” your electronics, while enjoying peace of mind in knowing that your electronics will continue to operate in the precise ways you want them to.

In terms of functionality, this module features an integrated RTC clock with clever circuitry and onboard buttons that allow for the selection of up to five different time periods and five different modes for time periods to operate according to. Furthermore, while this is primarily a relay module, it also includes an onboard buzzer, and when enabled, the buzzer can then act as a handy alarm. These relatively simple features all work beautifully together, allowing for automatic start and stop times that can be set according to specific times of each day, specific days of each month, or even a blend of specific times on specific days – offering true customisability for your electronics and automation projects.

Please Note: This module utilises a CR1220 Lithium Coin Cell to keep track of the time and date, although this is not included with the module, so be sure to add one to your cart when purchasing this so that you don’t run into unexpected problems.

Additional Note: In order to set the time and date of this module so that it can operate exactly as expected, press and hold the “DOWN” button for 2 to 3 seconds before releasing. The module should then enter Time Calibration mode, after which you can set the “YEA” year, “dAE” day and “HOU” hour settings, with a quick press of “SET” to accept and move onto each variable. Once you have set the “HOU” parameter, you need to put in the “YEA” parameter again, and then press and hold “SET” for 3 seconds to save and exit the time calibration interface.

1 Channel 5V Cycle Timer Relay Timing Modes:

This module is quite a smart module as, and even without any major microcontrollers or complex embedded chips, it offers a very impressive level of functionality, with five different modes to choose from, and each offering a distinct set of advantages over the others. Fortunately, while offering reasonably advanced functionality, they are quite simple to understand, and these modes are as follows:

P1 – Standard Operation: This is the standard Timing Mode, and results in standard relay operations repeated with daily frequency, but with the added benefit of having start and stop times as per the “OPE” and “CLE” parameters you set.

P2 – Time and Date: This next mode is almost exactly the same as P1 Standard Mode, but includes the “dAE” parameter so you can define the exact day in which you want the relay to activate and deactivate.

P3 – Time, Date & Month: This Timing Mode is quite similar to P2, but also includes the “MON” month variable, so that you can define precisely what days of each month – as well as the times on those days – that you want the relay to activate and deactivate.

P4 – Time, Predefined Range of Days: This mode is a slight step up from P3, and instead of defining precise days in which to operate, this mode lets you choose a range of days to operate, with the Month parameter included for a higher level of customisation.

P5 – Time, Monthly Start Date & End Date: Finally, the last mode is very much like P4, allowing you to define a range of days to operate, but repeats with a monthly frequency rather than just on a predefined set of dates.

These different Timing Modes are quite similar to each other, but as you can see, each one offers a distinct advantage that is better suited for various applications and use cases. And of course, when defining each time period (PE-1 to PE-5) you can easily choose between these above Timing Modes to best cater to your project, taking advantage of many of all of the different modes depending on what is best for your particular project and preferences.


Quick Guide to Calibrating the 1 Channel 5V Cycle Timer Relay:

Although this module offers an exceptional level of functionality and versatility, we must admit that it’s definitely not one of the easiest modules to use, but fortunately we’ve taken the time to experiment with and test out this board to figure out all of the cool features, and so we’ve prepared a nice little guide for you to follow, so as to get the very best level of functionality from this awesome little module.

Step 1 – The Time Period Interface: After powering up this module, it should display 00:00 on the 7-Segment display unit. To enter the calibration/settings mode from this standard interface, press and hold the “SET” button for three seconds or longer, after which it will change to display PE-1. You are now in the Time Period Settings Interface, where you can set up to five Time Periods (PE-1 to PE-5) for the relay module to activate and deactivate at. These Time Periods are independent of each other, and can each be set to custom times and dates depending on the modes chosen for each period. However, it’s important that these time periods don’t overlap with each other, as this can either cause unexpected problems, or will cause the module to return an “ERR” error state.

Step 2 – Timing Modes for Each Time Period: After choosing a time period in Step 1, the next step is to define what kind of mode you want that time period to operate in. The modes are listed in the “Timing Modes” section above, so be sure to acquaint yourself with them, and as mentioned in step 1, you can define different modes for each time period that you’re using. Additionally, you can set the mode of a time period to the “----’ option in order to disable/ignore that time period, and you can choose to disable as many or as few as you need in order to customise the timer to your specific needs.

Step 3 – Setting the Timing Parameters: Once you’ve chosen a time period and a timing mode for that period to adhere to, the next step is to define the actual start and stop times. This step will include putting in the “OPE” starting time, the “CLE” stopping time, as well as the “dAE” date – in that exact order – with the “SET” button being used to confirm each parameter. During this step, you can also hold the “STOP” button for 2 seconds to turn the alarm on and off, with “BLL0” representing Off and “BLL1” representing On. Furthermore, a quick press of the “STOP” button during this step will also change the output mode, with “OUT1” being standard relay operations, and “OUT2” being a special mode that outputs a 1 second pulse instead. This is perfect for activating other relays or various other modules, and can even simply trigger other components in your project rather than offering the standard on/off operations of a relay.

Step 4 – Confirming the Parameter Settings: Finally, once you’re done with setting the time periods you want, simply press and hold the “SET” button for 2 seconds before releasing, and the module will double-check all of the settings you input before going back to the standard interface. If the module logic finds an error in the time and date settings (as mentioned in Step 2) then it will display “ERR” and return to the parameter settings page, in which case you will have to repeat steps 1 to 3 so that no times or dates overlap. If you’re running into problems here, make sure to double check that the start time is set to before the end time, as this is the easiest mistake to make with this module. Then, once you’ve fixed up those parameters, come on back to step 4 and see if the module logic is happy with your new settings.
