Man, these little relays can handle some abuse! .

God these little relays can take some abuse! When I switched them to 5V (low triggers) I found that they could handle about 40 cycles per second, which is more than I expected. The response time is very short and they have a very pleasant activation sound (although quite loud). I will be testing these boards so I hope they hold up. Some of them occasionally see trigger rates in the 10Hz range, but nothing more extreme. In any case, they have to withstand this for several years before the relay fails.

Pros
