Hello Whostolemymonkey,

I tried to respond earlier to your message, but didn't know how to post this correctly:

You can use an RC network on the relay control line which needs to be delayed:<o:p></o:p>

<o:p> </o:p>Basicaly, the relay control signal will be slowed down through the RC network, and become somewhat of a ramp signal, rather than a square wave - like pulse. This will cause the relay with the filtered control signal path, to react slower than the relay without the control line filter, as the control signal will ramp slowly down to the relay coil turn on voltage threshold(towards ground voltage level), as the capacitor must discharge it’s current through the resistor through the relay control signal voltage source. Varying the values of the resistor and capacitor, will change the relay control signal ramp rate. The turn off time for the filtered relay control signal, will respond quickly however, as the capacitor has little resistance to impede with the charge current through the relay control coil. A series resistor can be placed between the relay control coil, and the capacitor, to slow the turn off time of the filtered relay. The resistance value should be kept as low as possible, so it won’t drop too much voltage, causing the relay coil to not function due to too small a voltage swing across it. Larger values of capacitance can be used to compensate for the smaller resistor values for the “R-C�?time constant.<o:p></o:p>
