Question:

In my case, I've got 20 values that must be logged every second, thus I need 20 lines per second, and as a result I can only log data for 1000 seconds on each data log file.

An SD card can store up to 50 data log files, so I can log data for 50000 seconds in total, which is 13.8 hours, correct?

No not really.

If you log 20 values at the same second, then the values in one line, not in 20 lines. 

Thanks a lot for your prompt response!

So, if I'm not mistaken you can have as many data logs as you want every second for 20,000 seconds on each data log file, and the total logs can be up to 20,000 x 50 = 1,000,000 seconds, which is 277 hours = 11.5 days of data logs.

I'm assuming that if I increase the logging frequency to 2 seconds, we will be able to log data for 23 days, and when all the 50 data log files are full, the oldest one is overwritten.

Am I right with all the above?

Hi,

you can configure up to 32 signals/values for datalogging. More cannot be configured.

Hope this helps

I use a generic much larger data card (I looked to buy the oldest one I can find) without trouble and I get at least xxxx data logging inputs, in excel. Use also "text to colums" to properly see them.
