該延時(shí)電路的**IC是由14位二進(jìn)制串行計(jì)數(shù)器/分頻器構(gòu)成，IC內(nèi)部由振蕩器和14級(jí)分頻器組成，振蕩器部分可由電阻Rt和電容Cr構(gòu)成振蕩器，產(chǎn)生固定的振蕩頻率,主振產(chǎn)生的矩形波可進(jìn)入14級(jí)分頻器，并通過10個(gè)輸出端得到不同的分頻系數(shù)（分頻**小可得到16分頻Q4，比較大可得到16384分頻Q14），便可得到所需的定時(shí)控制。待分頻延時(shí)到達(dá)后，輸出端的高電平使驅(qū)動(dòng)電路三極管導(dǎo)通工作，從而使執(zhí)行繼電器工作，相應(yīng)的延時(shí)觸點(diǎn)對所需**線路進(jìn)行定時(shí)控制，IC振蕩也隨輸出的高電平經(jīng)V6使之停振。發(fā)光管V1也隨繼電器同時(shí)工作，起到延時(shí)到達(dá)指示。
