       各位樓主:我接磁性開(kāi)關(guān)四個(gè)串在一起，四個(gè)開(kāi)關(guān)也都亮了，但是PLC,點(diǎn)不亮，接法絕對對，不知啥原因，每個(gè)開(kāi)關(guān)也都試過(guò)是好的，開(kāi)關(guān)好壞和接法不用懷疑，我以前串接過(guò)二個(gè)直接-30的接近開(kāi)關(guān)，開(kāi)關(guān)都亮，PLC點(diǎn)不亮，后來(lái)?yè)Q直徑18的開(kāi)關(guān)問(wèn)題解決了，像直流電源功率問(wèn)題，不知磁性開(kāi)關(guān)什么原因，磁性開(kāi)關(guān)功率很小的。

磁性開(kāi)關(guān)如果用在plc里不建議串聯(lián)，這樣不是每個(gè)信號都檢測到的
這個(gè)人很懶，什么也沒(méi)有留下！
