Conducting pipe control rechargeable delay circuit

  
Delay action, the instantaneous reset control circuit is divided into conducting pipe rechargeable delay circuit, tube cut-off control rechargeable delay circuit and a delay ci
Conducting pipe control rechargeable delay circuit - schematic

rcuit discharge type categories. Conducting pipe control rechargeable delay circuit Under normal circumstances, the input U., Negative potential, the transistor VTi conduction, VT2 off, the output U.. A negative potential. When [,. When zero potential, VTi off, VT2 conduction, the output goes to zero Use potentiometer. From U.. Zero potential to the U.. It becomes a zero potential time interval t is the delay time of the circuit.
