AI835 / AI835A muab 8 qhov sib txawv input channel rau Thermocouple / mV ntsuas. Kev ntsuas qhov sib txawv ntawm ib qho channel yog: -30 mV rau +75 mV linear, lossis TC Hom B, C, E, J, K, N, R, S thiab T, rau AI835A kuj D, L thiab U.
Ib qho ntawm cov channel (Channel 8) yuav raug teeb tsa rau "Cold Junction" (ambient) ntsuas kub, yog li ua haujlwm CJ-channel rau Ch. 1... 7. Qhov ntsuas kub ntawm qhov sib txuas yuav raug ntsuas hauv zos ntawm MTUs ntsia hlau terminals, lossis ntawm qhov chaw sib txuas nyob deb ntawm lub cuab yeej.
Xwb, kho qhov kub thiab txias rau lub module yuav raug teeb tsa los ntawm tus neeg siv (raws li qhov ntsuas) lossis rau AI835A kuj los ntawm daim ntawv thov. Channel 8 tuaj yeem siv tib yam li Ch. 1...7 thaum tsis muaj CJ ntsuas kub xav tau.
Nta thiab cov txiaj ntsig
- 8 qhov sib txawv input channel rau thermocouple / mV.
- Channel 8 tuaj yeem raug xaiv los ua CJ-channel (4-wire Pt100 RTD)
- Ntau yam ntawm cov thermocouples nrog cov yam ntxwv hauv qab no: B, C, E, J, K, N, R, S thiab T rau AI835A kuj D, L thiab U
- 15 ntsis daws teeb meem (A / D)
- Inputs raug saib xyuas rau cov hlau tawg qhib-circuit
