    Dear Experts

    I want to design a circuit/project - Whenever i will get +5VDC from one other circuitry then my 18 Volt DC latching relay should get energized for 20msec only after 20msec 18VDC will be d-energized

    Plz guide me

    Thanks & Regards

    20msec is too short for a relay to be energized,what is the relay switching?

    What sort of load are you trying to switch with it?

    Are you sure you want 20 Milli Seconds?

    20msec total or 20msec after input signal stops?

    Including the release time of the relay contacts?
