八路抢先电路和双路延时器的设计

Design of 8-Route Lead-up Circuit and 2-Route Delayer

本文介绍一种八路抢先电路和双路延时器的设计与制作,特点是采用可控硅元件作为抢先电路的关键元件,可以无限制地增加抢先电路的分组数目,同时解决了抢先电路和555延时电路的抗扰性问题。

The design and preperation of a kind of eight-route lead-up circuit and double-route delayer are introduced. The feature is using silicon-contralled rectifier as the key element so that the group number in lead-up circuit can be increased infinitely and the immunity of lead-up circuit and 555 delayer is improved.
