8-CH SSR 5A DC-DC 5V-220V ; SKU:20-018-959 | UPC:6955

Hello, can you help me ?

Before to buy ten of these, I need to know what happen if we put a square wave between 2Hz to 25Hz in the input of these SSR here below, which is the output artifact ?????

See attachment picture

I'm not English and I'm not an electronics technician, so a small drawing would be welcome

Thanks for your help

Is it this ?

If so, it uses these SSR devices.

These have a turn on / turn off time of min 1 mS. State what you are using it for and maybe some one can comment on its suitability for your application.
