Well, this review can be useful for those who did not insert how exactly this relay works.
Can work from 5V but via USB port and can from 7 to 30 if soldering to the board in marked places.
The delay time changes with variables on the board.
NC-COM closed by default
At COM-ON switches if the trigger is closed.
Switching back to NC-COM after the trigger broke and when the exposed time passed.
In fact, yes time relay, but out of the box can only be used as a delay between switches or switches.
I was looking for a delay just to turn on (after feeding, after a certain time, the relay includes the consumer). IIA though this is a crutch, but from 2 such relays you can make a delay switch relay.
And so relyuhi norms.
I hope someone helps when choosing.
