salve a tutti
come sempre cerco il vostro aiuto, questa volta avrei bisogno di uno schema per accendere un relay a 24VDC con un ritardo di 4/5 secondi, praticamente un anti bump per casse acustiche, molto semplice.
grazie a tutti voi
Guido
Hello everyone
as always seek your help, this time I need a schematic to turn on a relay 24VDC with a delay of 4.5 seconds, almost an anti bump for loudspeakers, very simple.
thank you all

You will find this interesting; 555 Timer Circuits
The 555 will drive a transistor to drive your speaker relay. Timing is R x C
The 555 will drive a transistor to drive your speaker relay. Timing is R x C
Here is a circuit that turns on a 12V relay, "X" seconds after AC mains power is applied. The delay "X" is adjustable by a 20-turn trimmer potentiometer. You can select any delay you wish, between (X= 2 seconds) and (X= 40 seconds).
BEWARE: this circuit connects to the AC mains. It could kill you.
