2-10V Sinyal Analizi<\/h2>

Yukar\u0131daki diyagramda g\u00f6sterildi\u011fi gibi:<\/p>

2-10V sinyal kablosunun uzunlu\u011fu, i\u00e7 direnci ve koruma \u00f6nlemleri, 2-10V sinyalinin parazitlere kar\u015f\u0131 direncini \u00f6nemli \u00f6l\u00e7\u00fcde etkiler. Kablo ne kadar uzun olursa, i\u00e7 direnci o kadar y\u00fcksek olur ve koruma ne kadar zay\u0131f olursa, 2-10V sinyalinin parazitlere kar\u015f\u0131 direnci o kadar k\u00f6t\u00fc olur. Bu nedenle, 2-10V genellikle \u00e7ok k\u0131sa mesafeli ileti\u015fim i\u00e7in kullan\u0131l\u0131r.<\/p>

4-20mA Sinyal Analizi<\/h2>

4-20mA Sinyali i\u00e7in Parazit \u00d6nleme \u015eemas\u0131 (DCL Huayi Ak\u0131ll\u0131 Kontrol)<\/strong><\/p>

2-10V'a k\u0131yasla, 4-20mA sinyali, 2-10V sinyalinin iki kritik zay\u0131f noktas\u0131n\u0131 giderir. Yukar\u0131daki \u015femada g\u00f6sterildi\u011fi gibi:<\/p>

4-20mA kullan\u0131ld\u0131\u011f\u0131nda, mod\u00fcl \u00fczerindeki daha d\u00fc\u015f\u00fck giri\u015f direnci (R=120 ohm) nedeniyle giri\u015f sinyal ak\u0131m\u0131 nispeten y\u00fcksektir (4mA \u2013 20mA). Bu, bu yol boyunca daha y\u00fcksek bir sinyal-g\u00fcr\u00fclt\u00fc oran\u0131na yol a\u00e7ar; yani iletken ve radyasyonel parazit \u00f6nleme performans\u0131 daha iyidir. Sonu\u00e7 olarak, 4-20mA sinyaline m\u00fcdahale etmek \u00e7ok daha zordur.<\/p>

4-20mA sinyal yolunda, \u00e7\u0131k\u0131\u015f cihaz\u0131, hem \u00e7\u0131k\u0131\u015f taraf\u0131ndaki ak\u0131m hem de akt\u00fcat\u00f6r giri\u015findeki ak\u0131m dahil olmak \u00fczere t\u00fcm \u00e7\u0131k\u0131\u015f d\u00f6ng\u00fcs\u00fc ak\u0131m\u0131n\u0131n do\u011frulu\u011funu sa\u011flayabilir. Bunun nedeni, \u00e7\u0131k\u0131\u015f devresinin geri besleme \u00f6rnekleme hedefinin 4-20mA d\u00f6ng\u00fcs\u00fcn\u00fcn \u00e7\u0131k\u0131\u015f ucundaki ak\u0131m olmas\u0131 ve ak\u0131m\u0131n t\u00fcm sinyal d\u00f6ng\u00fcs\u00fc boyunca e\u015fit olmas\u0131d\u0131r. Bu nedenle, akt\u00fcat\u00f6r ucunda \u00f6rneklenen ak\u0131m, kontrol cihaz\u0131ndan gelen \u00e7\u0131k\u0131\u015f ak\u0131m\u0131yla ayn\u0131 olmal\u0131d\u0131r. Giri\u015fim ve toprak potansiyeli tutars\u0131zl\u0131klar\u0131n\u0131n varl\u0131\u011f\u0131nda bile, 4-20mA \u00e7\u0131k\u0131\u015f devresi, aktif negatif geri besleme ayarlamas\u0131 yoluyla sinyal ak\u0131m\u0131n\u0131n do\u011frulu\u011funu sa\u011flayabilir.<\/p>

4-20mA sinyal kablosunun uzunlu\u011fu ve i\u00e7 direnci, 4-20mA sinyalinin parazit \u00f6nleme performans\u0131n\u0131 \u00e7ok az etkiler. Bu nedenle, 4-20mA genellikle uzun mesafeli ileti\u015fimde kullan\u0131l\u0131r.<\/p>

\u00c7\u00f6z\u00fcm<\/h2>

Sonu\u00e7 olarak, 4-20mA sinyali, end\u00fcstriyel ortamlarda 2-10V sinyaline k\u0131yasla \u00f6nemli \u00f6l\u00e7\u00fcde daha iyi parazit \u00f6nleme performans\u0131na sahiptir. Bu durum, elektrikli akt\u00fcat\u00f6rlerin kullan\u0131ld\u0131\u011f\u0131 uygulamalar i\u00e7in de ge\u00e7erlidir.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>","protected":false},"excerpt":{"rendered":"
