Looking for a 12–14V delayed-start relay/module for automotive use
Hi guys,
I’m looking for a simple delayed-start relay or timer module for my car.
I want it to work like this:
Ignition ON → wait 15 seconds → turn the wideband O2 controller ON → keep it ON until the ignition is switched OFF.
Since it’s for a car, it needs to work reliably at around 12–14.5V.
The wideband O2 controller already uses a normal automotive relay, so the timer only needs to trigger the relay coil.
Does anyone know of a reliable automotive-rated relay or module that would work for this without breaking the bank?
Thanks!
