Hello everyone, I want to switch my 4-channel relay module on and off quickly to control my active buzzer. Do you know what the switching frequency of the relay modules (the link is below) is? Can I switch the relay with a frequency of 5 or 2 Hz? Product link: https://www.wish.com/product/58772721…

Operate time for a Songle relay is >10ms, release time is >5ms.

How fast can a 4-channel relay module can switch?

Yes, for a few hours.
