德國PILZ安時間電器PNOZ X4,PILZ時間繼電器是一種利用電磁原理或機械原理實現(xiàn)延時控制的控制電器
它的種類很多，有空氣阻尼型、電動型和電子型等。交流電路中常采用空氣阻尼型時間繼電器，它是利用空氣通過小孔節(jié)流的原理來獲得延時動作的。它由電磁系統(tǒng)、延時機構(gòu)和觸點三部分組成。
pilz時間繼電器可分為通電延時型和斷電延時型兩種類型空氣阻尼型時間繼電器的延時范圍大（有0.4～60s和0.4～180s兩種）它結(jié)構(gòu)簡單，但準確度較低。當(dāng)線圈通電（電壓規(guī)格有ac380v、ac220v或dc220v、dc24v等）時，銜鐵及托板被鐵心吸引而瞬時下移，使瞬時動作觸點接通或斷開。但是活塞桿和杠桿不能同時跟著銜鐵一起下落，因為活塞桿的上端連著氣中的橡皮膜，當(dāng)活塞桿在釋放彈簧的作用下開始向下運動時，橡皮膜隨之向下凹，上面空氣的空氣變得稀薄而使活塞桿受到阻尼作用而緩慢下降。經(jīng)過一定時間，活塞桿下降到一定位置，便通過杠桿推動延時觸點動作，使動斷觸點斷開，動合觸點閉合。從線圈通電到延時觸點完成動作，這段時間就是繼電器的延時時間。延時時間的長短可以用螺釘調(diào)節(jié)空氣進氣孔的大小來改變。 　　吸引線圈斷電后，繼電器依靠恢復(fù)彈簧的作用而復(fù)原?？諝饨?jīng)出氣孔被迅速排出。
PILZ繼電器是具有隔離功能的自動開關(guān)元件，廣泛應(yīng)用于遙控、遙測、  繼電器（圖3）
通訊、自動控制、機電一體化及電力電子設(shè)備中，是zui重要的控制元件之一。 　　繼電器一般都有能反映一定輸入變量（如電流、電壓、功率、阻抗、頻率、溫度、壓力、速度、光等）的感應(yīng)機構(gòu)（輸入部分）；有能對被控電路實現(xiàn)“通”、“斷”控制的執(zhí)行機構(gòu)（輸出部分）；在繼電器的輸入部分和輸出部分之間，還有對輸入量進行耦合隔離，功能處理和對輸出部分進行驅(qū)動的中間機構(gòu)（驅(qū)動部分）
