Lefoo I-Multi-Function Differential Premitter LFM73

Uchungechunge lwe-LFM73 lwe-dijithali yedijithali yokubonisa ehlukile / izilawuli zisebenzisa inzwa ephezulu ye-MEMS, Isikhombiso sedijithali se-LED, nokukhipha isidlulisi ukuthola umehluko wengcindezi; ingashintsha ngokuphelele igeji yengcindezi yohlobo lwesikhombisi; Ububanzi besilinganiso sokulinganisa ingcindezi neyunithi yengcindezi yalesi sidluliseli sokucindezela kungalungiswa kalula esizeni ngezinkinobhi .. I-Uchungechunge lwe-LFM33Isidlulisi sokucindezela okuhlukileYamukela izindlu zebanga lokuvikela i-IP65 futhi ilungele izinhlelo zokuphatha amandla, ukushisa, umoya, kanye ne-air conditioning (HVAC), i-VAV kanye nokulawulwa kwabalandeli, ukulawulwa kokungcola kwemvelo, ipayipi elimile kanye nesilinganiso sengcindezi yegumbi elihlanzekile, ukulawulwa kwe-hood yomusi, ukucindezelwa kwe-havin nokulawulwa kokungenisa umoya wokubilisa nezinye izinkambu.

UKUBA: Ngamanye amamodeli womkhiqizo, sicela ubhekise kulwazi olungaphezulu komkhiqizo ngezindlela ezithile zokugcina izintambo.

Izinyathelo Zokuqapha Ukufaka:

Ukufakwa nezintambo kufanele kwenziwe ngochwepheshe abafanelekayo. Amandla kufanele avulwe ngesikhathi sokugcina izintambo. Lapho i-transmitter inikwe amandla ngamandla kagesi angama-24VAC, kunconywa ukuthi kusetshenziswe amandla e-AC ahlukaniswe nge-transformer. Lapho isidlulisi sabelana ngamandla angama-24VAC neminye imishini, kuyadingeka ukuqinisekisa ukuxhumana okuthembekile phakathi kuka-24V no-GND. Ngaphandle kwalokho, kungase kube nesimo esingalindelekile, noma ngisho nomonakalo emishinini.
