中電阻R1和R2的取值必須使當(dāng)輸入為+VCC時(shí)的三極管可靠地飽和，即有βIbIes在.21中假設(shè)Vcc=5V，Ies=50mA,β=100,則有Ib0.5mA而Ib=(Vcc-Vbe)/R1-Vbe/R2若取R2=4.7K，則R16.63K,為了使三極管有一定的飽和深度和兼顧三極管電流放大倍數(shù)的離散性，一般取R1=3.6K左右即可。若取R1=3.6K，當(dāng)集成電路控制端為+VCC時(shí)，應(yīng)能至少提供1.2mA的驅(qū)動(dòng)電流(流過(guò)R1的電流)給本驅(qū)動(dòng)電路，而許多集成電路(標(biāo)準(zhǔn)8051單片機(jī))輸出的高電平不能達(dá)到這個(gè)要求，但它的低電平驅(qū)動(dòng)能力則比較強(qiáng)(標(biāo)準(zhǔn)8051單片機(jī)I/O口輸出低電平能提供20mA的驅(qū)動(dòng)電流(這里說(shuō)的是漏電流))，則應(yīng)該用如.22所示的電路來(lái)驅(qū)動(dòng)繼電器。

JS7一A系列空氣時(shí)間繼電器：是利用氣囊中空氣通過(guò)小孔節(jié)流的原理來(lái)獲得延時(shí)動(dòng)作的。根據(jù)觸頭延時(shí)的特點(diǎn)，它可以分為通電延時(shí)動(dòng)作（如JS7一2A型）斷電延時(shí)復(fù)位（如JS7一4A型）兩種。JS一A系列的結(jié)構(gòu)圖如下圖所示：JS7一A系列時(shí)間繼電器由電磁系統(tǒng)、工作觸頭、氣室及傳動(dòng)機(jī)構(gòu)等四部分組成。其中電磁系統(tǒng)：由線圈、銜鐵和鐵芯組成，另外還有反力彈簧和彈簧片。工作觸頭：由兩副瞬時(shí)觸頭（一副瞬時(shí)閉合，另一副瞬時(shí)斷開(kāi)）及兩副延時(shí)觸頭組成。
