Yog vim li cas Industrial Qib Matters - Qhov no tsis yog kev yuav khoom ntawm cov neeg siv khoom
Qhov xwm txheej tiag tiag: lub Hoobkas hauv pem teb HMI ua tsis tiav tom qab 8 lub hlis vim yog tus neeg siv khoom- qib vaj huam sib luag
Lub chaw ua zaub mov tau teeb tsa cov neeg siv khoom- qib 7-nti zaub hauv lawv cov kab ntau lawm HMIs. Tsis pub dhau yim lub hlis, cov av noo thiab kub hloov pauv tau ua rau ntau qhov kev ua tsis tiav, ua rau cov khoom lag luam nres thiab kev hloov pauv thaum muaj xwm txheej ceev uas raug nqi ntau dua li kev yuav cov vaj huam sib luag tsim nyog txij thaum pib.
Dab tsi "industrial grade" txhais tau tias hauv kev lag luam zaub
Nws yog hais txog cov khoom tsim kho rau cov xwm txheej hnyav: qhov kub thiab txias ntau dua, siab dua MTBF, kev tsim kho tshuab muaj zog dua, thiab ntev dua - lub sij hawm muaj nyob.
Tus nqi ntawm qhov tsis ncaj ncees lawm: downtime, hloov, thiab rov tsim cov nuj nqis
Daim ntawv qhia kev yuav khoom no yog sau rau leej twg
Cov lus qhia no yog rau OEM engineers, automation specialists, thiab procurement professionals nrhiav 7 nti lcd zaub daws teeb meem rau cov ntawv thov kev lag luam.
Industrial vs Consumer Qib 7 Nti LCD - Dab tsi yog qhov txawv?
Cov khoom zoo: qib capacitor, backlight binning, tsav IC xaiv
