pilz安全繼電器PZA 300/24VAC 1n/o 2n/c ：PILZ皮爾茲安全繼電器在機(jī)床的應(yīng)用：兩對(duì)觸點(diǎn)的繼電器（即樓主所說(shuō)的8腳繼電器）標(biāo)準(zhǔn)分布是這樣的： 13、14是線圈。一般14接正、13接負(fù)。 1、5、9 是一對(duì)觸點(diǎn)，1、9 常閉，5、9 常開(kāi)。 4、8、12是一對(duì)觸點(diǎn)，4、12常閉，8、12常開(kāi)。四對(duì)觸點(diǎn)的繼電器（14腳繼電器）標(biāo)準(zhǔn)分布是這樣的： 　　13、14是線圈。

pilz安全繼電器PZA 300/24VAC 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(diǎn)等組成的。只要在線圈兩端加上一定的電壓，線圈中就會(huì)流過(guò)一定的電流，從而產(chǎn)生電磁效應(yīng)，銜鐵就會(huì)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(dòng)銜鐵的動(dòng)觸點(diǎn)與靜觸點(diǎn)（常開(kāi)觸點(diǎn)）吸合。當(dāng)線圈斷電后，電磁的吸力也隨之消失，銜鐵就會(huì)在彈簧的反作用力返回原來(lái)的位置，使動(dòng)觸點(diǎn)與原來(lái)的靜觸點(diǎn)（常閉觸點(diǎn)）吸合。這樣吸合、釋放，從而達(dá)到了在電路中的導(dǎo)通、切斷的目的。對(duì)于繼電器的“常開(kāi)、常閉”觸點(diǎn)，可以這樣來(lái)區(qū)分：繼電器線圈未通電時(shí)處于斷開(kāi)狀態(tài)的靜觸點(diǎn)，稱為“常開(kāi)觸點(diǎn)”；處于接通狀態(tài)的靜觸點(diǎn)稱為“常閉觸點(diǎn)”。
