style="text-indent:25px">高精度角度編碼器解決信號(hào)問題方案的特點(diǎn)如下：1．HXM58系列編碼器為機(jī)械齒輪組真多圈絕對值編碼器，外形安裝尺寸完全與原來的德國進(jìn)口SSI編碼器相同，安裝上可直接替換。編碼器外殼防護(hù)等級(jí)為IP67，溫度等級(jí)為-40度—80度，符合水利潮濕、高低溫的使用。2．雙輸出的信號(hào)為4—20mA和RS485，可傳輸距離400米—1000米（依據(jù)電纜），符合直接遠(yuǎn)傳要求；此兩種信號(hào)都有成熟的、大量已使用的防雷器，對信號(hào)端口（無論是編碼器還是接收設(shè)備）可起到保護(hù)作用。3．所有的PLC都可以有4—20mA接口，大部分的PLC也可以連接RS485信號(hào)，這樣對于PLC的可選面就極大增加，成本就可以下來；而4—20mA和RS485信號(hào)，也可以找到標(biāo)準(zhǔn)的、成熟的儀表，以增加儀表的可靠性并降低成本。PLC和儀表，可以相互選擇使用4—20mA信號(hào)還是RS485信號(hào)。4．編碼器雙信號(hào)分別進(jìn)手動(dòng)現(xiàn)地控制與自動(dòng)PLC控制，兩套控制既可以**，又可以相互冗余，控制安全性可以極大增強(qiáng)，而成本卻可以下降。由于可以增加安裝防雷器，今后的維護(hù)備件成本也下降了。當(dāng)電源斷開時(shí)，相對型高精度角度編碼器并不與實(shí)際的位置分離。</p><div
