1794-IE8 Allen-Bradley modul na analog mai ɗimbin tashoshi na ƙarfin lantarki da ƙarfin wuta (current)

Takaitaccen Bayanin Samfur

1794-IE8 wani modul ne na Analog Input mai ƙirar high-density daga sanannen layin kayan Allen-Bradley FLEX IO. Yana da tashoshi 8 na shigarwa single-ended, wanda ke ba da sassauƙar sa ido kan kayan aunawa ta hanyar karɓar siginar filin na current (0–20 mA, 4–20 mA) da voltage (±10 VDC, 0–10 VDC). Tsarin sa na modular yana haɗa sarari tsakanin na’urorin firikwensin a fili da cibiyoyin sarrafawa, yana bawa injiniyoyi damar haɗa na’urori irin su flow meter, na’urar auna zafi (temperature transmitter), da na’urar auna matsa lamba (pressure transducer) cikin daidaito.

Tambayoyi na Fasaha (FAQs)

Q1: Zan iya haɗa na’urorin siginar current 4–20 mA da na siginar voltage 0–10 VDC a kan modul ɗin 1794-IE8 ɗaya?
A1: I, za a iya. 1794-IE8 yana tallafawa gaurayen saituna a cikin tashoshinsa 8. Za ka iya ware wasu tashoshi su zama na current, wasu kuma su zama na voltage ta hanyar haɗa wayoyi zuwa daidaitattun terminal da kuma daidaita rajistar saitin ciki na modul ɗin yadda ya dace.

Q2: Me ya sa daidaitaccen grounding yake da muhimmanci ga tsarin shigarwar single-ended na 1794-IE8?
A2: Shigarwar single-ended suna raba hanyar dawowa guda ɗaya a cikin modul ɗin. Idan an yi grounding na na’urorin filin a wurare daban-daban na masana’anta da ke da bambancin ƙarfin lantarki, hakan na iya kawo ground current a cikin hanyar sigina, wanda zai jawo kuskuren auna ko karkacewar bayanai.

Q3: Shin katin 1794-IE8 yana tallafawa hot-swapping kai tsaye idan wani tashar ta lalace?
A3: I, a matsayinsa na ɓangare na dangin Allen-Bradley FLEX IO, 1794-IE8 yana goyon bayan Removal and Insertion Under Power (RIUP). Wannan yana ba ka damar maye gurbin modul da ya lalace ba tare da kashe wutar sauran rack ɗin faɗaɗa ba ko katse sadarwar cibiyar sadarwa da babban PLC.
