help with muting relay
hello, working on a muting relay circuit, this will unground (unshort) the preamp output a few seconds after startup allowing the preamp output to flow on to the next stage. (esp design)
any suggestions on a relay i could use for this?
source ac will be around 20v (i know how to bring it down if need be to a lower voltage), needs to pull around 15ma at the coil and the 20v ac applied will disconnect the grounded preamp outputs.
i have no idea how to go about choosing a relay.. any help for this newb?
Look for small signal type relays "<2A".
I have a preference for IM series of relays (DigiKey)
I have also used G6K types.
The IM have a minimum switching voltage of 100uV. This is the type of number that is nice to find in the data sheet.
The G6K types have a "Min. permissible load" of 10 μA at 10 mVDC.
You will want to have very small numbers like this for signal switching.
IMHO of course.
excellent, i really appreciate it, sir! that helped tremendously. i kinda lost with all of the options for relays!
kinda new to the whole diy world.. and there are a lot of options to choose from. digikey is not the easiest to navigate when you don't know what you are looking for.
the g6k model is exactly what i am looking for.
