WebThe reason it is slow is because when the circuit to the relay coil opens, all the energy stored in the relay coil forces a current thru the flywheel diode until that energy is "spent". The diode acts like a short circuit with a small forward volt-drop and with the resistance of the relay (maybe 100 ohms), it will delay the relay de-activating a few extra milli-seconds.
