Hi there,
I have been scouring the internet and can't seem to find an answer to this.
I want to know, either on average or where to find it for a specific model, how long it take for the switch to switch positions on lets say a Double Throw relay.
To preface, I am building a circuit that will use a capacitor to latch a relay. I want to know the minimum time i need to energize it in order for it to latch.
Here's a specific relay we can use for this. It is a general omron relay 12v, 278 ohm coil.
Here is what i have, i calculated that at 278 ohms i can get a charge time constant of about .028s using a 100uF cap at 12V
From what I know, that time constant is for it to reach about 2/3 total charge. This means at that time i would be passing about 8 volts.
According to the relay spec sheet i need at minimum 8.5 volts to energize the coil.
For my circuit to work. I need to have the time between my cap charging that last 30% or so to be long enough to energize the coil and latch the relay.
My unknown is what that time is. (also i know the cap charging is not linear, need to look into that more)
My thinking was if i know the relay time to close is lets say 3ms, I can use that to size my capacitor better.
I unfortuantley dont have any equipment that is fast enough to monitor these state changes.
Any ideas would be lovely! Thank you!
Cheers!
