What's X20DO6639 Max Switching frequency

As you can see in as help,it only show X20DO6639 Switching delay ,what’s X20DO6639 Max Switching frequency

Hello Wenbin!

If you want be blunt about it you just take the sum of switch on and off == 20ms so you’ll end up with min. 50 Hz?! :slight_smile:

I guess that is what it should be able to deliver as minimum frequency. But since it says the delays can always be up to 10 ms, that’s the only thing you’ll be guaranteed I guess…

Best regards,

Hi Wenbin,

the X20DO6639 is a relay based module and therefore not intended to output a ‘frequency’ due to the limited life of mechanical contacts.
Furthermore you will notice a bouncing of the contacts.

I didn’t want to encourage to use it as PWM or something like that :smiley:
Just considering the max possible freq. for a few switches.

The expected lifetime is also printed out in the help:
