摘要
介绍一种延时整数秒的控制电路,能在启动信号出现时,经整秒延时后,才对控制的对象发出控制信号。而且该电路的延迟时间还能在1~9s之间任意设置,若需要还可扩展延迟时间。
A delayed control circuit with integral seconds is intriduced. Once the starting signal occurs the control signal to the target will be output for integral seconds.seconds the delay can be preset from 1 to 9 seconds The settings can be expanded if mecessary.
