ABB AI880A 3BSE039293R1 Imodyuli yoNgeniso yeAnalog yeMfezeko ePhezulu
Imodyuli yoNgeniso ye-AI880A ePhezulu ye-Analog yenzelwe ukucwangciswa okukodwa kunye nokungafunekiyo. Imodyuli inamajelo asi-8 akhoyo ngoku. Ukuchasana kwegalelo yi-250 ohm.
Imodyuli isasaza unikezelo lwe-transmitter yangaphandle kwitshaneli nganye. Oku kongeza uxhulumaniso olulula ukusabalalisa unikezelo kwii-2- okanye ezi-3-wire transmitters. Amandla othutho ajongwe kwaye okwangoku alinganiselwe. Zonke iitshaneli ezisibhozo zodwa kwiModuleBus kwiqela elinye. Amandla kwiModyuli aveliswa kwi-24 V kwiModuleBus.
I-AI880A ihambelana ne-NAMUR ncomo ye-NE43, kwaye ixhasa uqwalaselo phezu-naphantsi kwemida yoluhlu.

Imibuzo edla ngokubuzwa malunga nemveliso yile ilandelayo:
-Yintoni i-ABB AI845?
I-ABB AI845 yimodyuli yokufaka i-analog eguqula iimpawu ze-analog kwiidatha zedijithali ezinokuthi ziqhutywe inkqubo yokulawula. Ngokuqhelekileyo isetyenziselwa ukudibanisa kunye nezixhobo zoluvo kunye nezixhobo ezivelisa izibonakaliso ze-analog, ezifana nezinzwa zobushushu (i-RTDs, i-thermocouples), izidlulisi zoxinzelelo, kunye nezinye izixhobo ezinxulumene nenkqubo.
-Ziziphi iintlobo zeempawu zegalelo ezinokusingatha imodyuli ye-AI845?
Iimpawu zangoku (4-20 mA, 0-20 mA).
I-Voltage (0-10 V, ± 10 V, 0-5 V, njl.) iimpawu
Ukumelana (i-RTDs, i-thermistors), kunye nenkxaso kwiintlobo ezithile ezifana ne-2, i-3, okanye i-4-wire RTDs
I-Thermocouples (enembuyekezo efanelekileyo yesiphambuka esibandayo kunye nomgca)
-Ziziphi iimfuno zamandla kwi-AI845?
I-AI845 idinga umbane we-24V DC ukuze isebenze.
