Txheej txheem cej luam
Thermistor input isolation safe barrier with surge protection function can convert the Pt100 signals of two wire and three wire thermistors (RTDs) nyob rau hauv cov chaw muaj kev phom sij rau hauv 1: 1 teeb liab ntawm lub thermistor thiab xa mus rau thaj chaw nyab xeeb. Nws tuaj yeem tsim kho tau zoo, thiab qhov tseeb ntau yam ntawm cov thermal kuj tuaj yeem teeb tsa los ntawm computer software. Nws muaj lub luag haujlwm ntawm lub tswb tawg tawg thiab tawm ntawm lub tswb nrov.
Cov khoom no yuav tsum muaj kev ywj pheej fais fab, nrog cov khoom siv hluav taws xob sib cais, cov tswv yim, thiab cov khoom siv tawm.

Nco tseg:
1. Lub hwj chim rail muaj nuj nqi yog ib qho kev xaiv muaj nuj nqi, thiab cov neeg siv yuav tsum tau qhia kom meej lub hwj chim txoj kev thaum muab ib qho kev txiav txim.
Kev xaiv ntawm fais fab rail connectors tuaj yeem xa mus rau nplooj 89 ntawm "Annex"
2. Thaum nkag rau peb xaim RTD, nws yog ib qho tsim nyog los xyuas kom meej tias peb cov xov hlau muaj qhov sib npaug ntawm qhov ntev li ntau li ntau tau
3. Thaum muab ob-xaim RTD, kev ruaj ntseg barrier terminals 5 thiab 6 yuav tsum luv luv circuited
