Txheej txheem cej luam
Lub tshuab cais hluav taws xob tiv thaiv kev poob siab analog input signal isolator tuaj yeem hloov ob lossis peb-xaim 4 ~ 20A lossis cov teeb liab tam sim no mus rau hauv cov teeb liab tam sim no lossis voltage los ntawm lub isolator. Cov kev teeb tsa tso zis tuaj yeem hloov kho raws li tus neeg siv xav tau.
Cov khoom no yuav tsum tau siv hluav taws xob ntawm nws tus kheej, thiab lub hwj chim muab hluav taws xob, cov tswv yim thiab cov zis tawm raug cais tawm.
