ABB Ai845 3Bse023675r1 Analog Cov Lus Qhia Module
Lub Ai845 analog cov tswv yim module rau ib qho lossis redundant cov ntawv thov. Tus qauv muaj 8 channel. Txhua tus channel tuaj yeem yog tus qauv hluav taws xob lossis cov tswv yim tam sim no thaum mtu tu844 lossis siv tau, thaum lwm tus MTus tau siv txhua channel ua voltage los yog cov nkag tshiab.
Cov khoom siv hluav taws xob thiab cov tswv yim tam sim no muaj peev xwm tiv thaiv cov kev txhawb nqa ntawm tsawg kawg yog 11 v DC Lub tswv yim tsis kam tshaj yog 250 Ohm.
Cov qauv hloov kho sab nraud Hart cov khoom siv hloov kho rau txhua tus channel. Qhov no ntxiv qhov kev sib txuas yooj yim los faib cov khoom rau 2-xaim lossis 3-hlau transmitters. Lub tshuab xa hluav taws xob muaj kev saib xyuas thiab kev txwv tam sim no.

Cov Lus Nquag Nug txog cov khoom yog raws li hauv qab no:
-What yog Abb Ai845?
ABB Ai845 yog ib qho qauv analog uas hloov cov cim analog rau cov ntaub ntawv digital uas tswj tau cov txheej txheem. Nws yog feem ntau siv rau conterface nrog cov cim qhia thiab cov khoom siv analog cov cim, xws li cov ntsuas kub (RTDs, thiab lwm yam kev hloov pauv ntawm cov txheej txheem.
-Tus hom cov tswv yim cov cim qhia tau cov cim npe Ai845 tus qauv?
Tam sim no (4-20 ma, 0-20 ma)
Voltage (0-10 V, ± 10 V, 0-5 V, thiab lwm yam)
Kuj (RTDs, Tus Khwv, Nrog Txhawb rau cov hom tshwj xeeb xws li 2, 3, lossis 4-hlau RTDs
Thermocows (nrog kev pab cuam tshuam txias thiab linearization)
-What yog lub zog uas yuav tsum muaj rau Ai845?
Lub Ai845 yuav tsum tau 24V DC fais fab ua haujlwm ua haujlwm.
