Izimiso Zokulawula Izinga lokushisa kwesithando sokushisa esingeniswayo e-India

Umgomo wokulawula izinga lokushisa waseNdiya isithando sokushisa sangaphakathi kuboniswa esithombeni esinamathiselwe. Leli bhodi lihlanganisa izingxenye ezimbili zokulawula izinga lokushisa, futhi isignali yokufaka yokulawula izinga lokushisa ithatha isignali yamanje evamile engu-0-20mA. Isignali yamanje ikhishwa njengesignali ye-voltage nge-R52, bese ibalwa nge-voltage yetheminali ehambayo engu-W, bese ikhuliswa futhi ikhishwe yibhulokhi ehlanganisiwe ye-U1D. I-voltage ephezulu yokuphumayo inqunywa izinga letheminali engu-W enyakazayo kusekethe yokulawula izinga lokushisa. Okokufaka kokulawula izinga lokushisa ngu-0 ~ Isignali yamanje engu-20mA iguqulwa ibe isignali kagesi ngo-R52 futhi iqhathaniswe nezinga le-potentiometer yangaphandle engase ihambe. Umehluko kagesi phakathi kwakho kokubili ukhuliswa yi-U1D ukuze uguqule i-voltage ephumayo. Ibanga loshintsho linqunywa ngama-R54 kanye nama-R51, ngokuvamile ku-It isethwe izikhathi ezingaba ngu-10 lapho iphuma efektri. Setha umehluko we-voltage phakathi kwe-UR52 ne-UW2 ukuthi ibe ngu-0.1V, futhi amandla kagesi kutheminali okukhiphayo ye-U1D kufanele abe ngu-1V. Emsebenzini ojwayelekile, iphoyinti elinikeziwe lokuphumayo elingu-BH linamandla aphansi, ngemva kokuba isilawuli sezinga lokushisa sivuliwe, okukhiphayo kunamandla amakhulu, futhi ukuphuma kwamandla okuphuma kwamandla okuvama okumaphakathi kuthuthukela ezingeni eliphansi. Ukufeza inhloso yokulawula izinga lokushisa. Izinga lokushisa linqunywa izinga letheminali eguqukayo engu-W. Ngokuvamile, inani le-W lenkomba yezinga lokushisa lingalungiswa ngokufanele.
