ABB AI895 3BSC690086R1 Analog Module Input
Qalabka analogga ah ee AI895 wuxuu si toos ah ugu xiri karaa gudbiyaasha 2-fire, iyo xiriiro gaar ah, waxay sidoo kale ku xiri kartaa gudbiyaasha 4-fire iyada oo aan lumin shaqada HART. Qalabka analogga ah ee AI895 wuxuu leeyahay 8 kanaal. Cutubka waxaa ku jira qaybo ilaalin oo ammaan ah oo ku yaal kanaal kasta oo loogu talagalay isku xirka aaladaha habka meelaha halista ah iyada oo aan loo baahnayn qalab dheeraad ah oo dibadda ah.
Kanaal kastaa wuxuu awoodaa oo la socon karaa gudbiyaha habsocodyada silig-labada ah iyo xidhiidhka HART. Hoos-u-dhaca danab-gelinta wax-soo-gelinta ee hadda jira waa 3 V, oo ay ku jirto PTC. Korontada gudbiyaha ee kanaalka kasta ayaa awood u leh in uu bixiyo ugu yaraan 15 V at 20mA loop current si uu u koronto gudbinta habsocod hore oo shahaado ah, oo ku xaddidan 23 mA xaaladaha culeyska xad dhaafka ah.

Su'aalaha inta badan la is weydiiyo ee ku saabsan alaabta waa sida soo socota:
Waa maxay ABB AI895 3BSC690086R1?
ABB AI895 3BSC690086R1 waa qayb galinta analoogga ah ee iska leh ABB's System 800xA ee badeecooyinka. Inta badan waxaa loo isticmaalaa in lagu helo calaamadaha analoogga ee nidaamyada otomaatiga ah oo loogu beddelo calaamadaha dhijitaalka ah si loo sii farsameeyo iyo falanqaynta.
-Immisa kanaal wax gelin ah ayay leedahay?
AI895 3BSC690086R1 waxay leedahay 8 kanaal wax gelin oo kala duwan oo u heellan cabbirka kuleylaha/mV.
Waa maxay cabbirkeeda?
Kanaal kasta waxa loo habayn karaa in lagu cabbiro inta u dhaxaysa -30mV ilaa +75mV linear, ama nooca kulaylaha u dhigma.
-Waa maxay sifooyinka qaabeynta kanaalka?
Mid ka mid ah kanaalada (channel 8) waxaa loo habeyn karaa cabbirka heerkulka "dhamaadka qabow" (ambient), marka waxaa loo isticmaali karaa kanaalka CJ ee kanaalka.
