PILZ繼電器PZA 300/24VDC 1n/o 2n/c：PILZ皮爾茲安全繼電器的原理：PILZ安全繼電器一般由鐵芯、線圈、銜鐵、觸點等組成的。只要在線圈兩端加上一定的電壓，線圈中就會流過一定的電流，從而產生電磁效應，銜鐵就會在電磁力吸引的作用下克服返回彈簧的拉力吸向鐵芯，從而帶動銜鐵的動觸點與靜觸點（常開觸點）吸合。

PILZ繼電器PZA 300/24VDC 1n/o 2n/c：

PILZ皮爾茲安全繼電器在機床的應用：兩對觸點的繼電器（即樓主所說的8腳繼電器）標準分布是這樣的： 13、14是線圈。一般14接正、13接負。 1、5、9 是一對觸點，1、9 常閉，5、9 常開。 4、8、12是一對觸點，4、12常閉，8、12常開。四對觸點的繼電器（14腳繼電器）標準分布是這樣的： 　　13、14是線圈。一般14接正、13接負。1、5、9 是一對觸點，1、9 常閉，5、9 常開。 　　2、6、10是一對觸點，2、10常閉，6、10常開。 3、7、11是一對觸點，3、11常閉，7、11常開。 　　4、8、12是一對觸點，4、12常閉，8、12常開。

PILZ皮爾茲安全繼電器原理要求及應用如下：
PILZ皮爾茲安全繼電器的原理：PILZ安全繼電器一般由鐵芯、線圈、銜鐵、觸點等組成的。只要在線圈兩端加上一定的電壓，線圈中就會流過一定的電流，從而產生電磁效應，銜鐵就會在電磁力吸引的作用下克服返回彈簧的拉力吸向鐵芯，從而帶動銜鐵的動觸點與靜觸點（常開觸點）吸合。當線圈斷電后，電磁的吸力也隨之消失，銜鐵就會在彈簧的反作用力返回原來的位置，使動觸點與原來的靜觸點（常閉觸點）吸合。這樣吸合、釋放，從而達到了在電路中的導通、切斷的目的。對于繼電器的“常開、常閉”觸點，可以這樣來區分：繼電器線圈未通電時處于斷開狀態的靜觸點，稱為“常開觸點”；處于接通狀態的靜觸點稱為“常閉觸點”。
