Siv cov kev sib tw uas twb muaj lawm - hom davhlau ya nyob twg ncej ntsia hlau txuas tshuab, thiab ntxiv ib lub voj voog uas muaj cov khoom siv hluav taws xob, kev sib txuas ntawm cov txheej txheem photoelectric tau paub.
Lub hauv paus ntawm kev tswj tsis siv neeg yog tias chav tswj yuav tsum muaj kev ntseeg siab cais tawm ntawm cov sensors thiab actuators kom tsis txhob cuam tshuam. Voltage matching, nws kuj tseem siv tau los ua ib qho kev sib txuas ntawm cov txheej txheem tswj peripherals thiab tswj, teeb liab thiab regulator li, thiab yog haum rau txawv voltage thiab hwj chim ranges.
Optical isolation terminals muaj qhov zoo ntawm qhov tsis tshua muaj kev tswj lub davhlau ya nyob twg teeb liab poob, siab hloov zaus, tsis muaj kev sib cuag ntawm cov neeg kho tshuab, tsis muaj kev hloov pauv, hluav taws xob hluav taws xob siab, tsis ntshai kev vibration, tsis cuam tshuam los ntawm txoj hauj lwm thiab lub neej ntev, yog li lawv tau siv dav hauv cov khoom siv hluav taws xob. teb ntawm kev tswj tsis siv neeg.
