Help, I need a 5 second Logic Delay
Help, I need a 5 second Logic Delay
(OP)
I have a logic circut, basically I have the output of an OR gate driving a reley driver but I need to delay this Logic signal 5 seconds before the relay driver.
Basically how the circuit works is I have several inputs and if any of these inputs goes High my relay driver turns on the relay and I need to delay this 5 seconds before the relay turns on and when the input goes Low again the relay will turn off and any timer I have should reset.
Any ideas??????

I appretiate your help...

If o/p of existing OR and MONOSHOT are fed to AND gate, the gate o/p would provide delayed HIGH signal to relay driver. If i/p goes low AND gate o/p goes low as well.

case I suggest an integrator with a long time constant
followed by comparator which sets a FF. The FF discharges the integrator. Reset : manual push botton ?
Do you have FAX #?
