Allen-Bradley 1762-IF4 MicroLogix Modul Ɗaukar Siginar Analog Mai Hanya 4

Bayani Kan Samfuri

1762-IF4 yana faɗaɗa ƙarfin masu kula MicroLogix ta hanyar samar da tashoshi huɗu na siginar analog na bambanci masu daidaito sosai. An ƙera wannan modul ne don haɗawa da nau’o’in sensoci na masana’antu iri-iri, yana mai da siginar ƙarfin lantarki ko na yanzu (voltage ko current) zuwa bayanan dijital ga mai kula (controller). 

Manyan Fa’idodin Fasaha

Wannan modul ɗin yana da tashoshi huɗu na bambanci (bipolar) waɗanda ke kawar da hayaniyar common-mode yadda ya kamata, suna tabbatar da ingancin sigina a muhalli na masana’antu da ke da hayaniyar lantarki. Kayan aikin yana tallafawa ma’aunin shigarwa iri-iri, ciki har da daidaitaccen ±10V DC da siginar 4-20mA, yana ba da sassauci wajen haɗa tsofaffin kayan aunawa da na zamani. Tare da maimaituwa (repeatability) na ±0.12%, na’urar tana tabbatar da daidaiton aiki na dogon lokaci. Tsarin cin ƙarfin lantarki kaɗan (yawanci 1.2W) yana rage zafin da ke hauhawa a kan 1762 bus, yana ƙara amincin aiki da tsawon rayuwar dukan tire na PLC.

Shigar da modul ɗin a gefen dama na mai kula MicroLogix ko a gefen modulolin faɗaɗawa na kusa ta amfani da haɗin 1762 bus da aka haɗa a ciki. Don samun kwanciyar sigina mafi kyau, koyaushe yi amfani da igiyoyin twisted-pair masu murfi (shielded) masu inganci, kamar Belden 8761. Ka tabbatar an haɗa murfin ƙasa (ground) a gefe guda kawai (yawanci a gefen PLC) don guje wa ground loop. Don kiyaye maimaituwa ta ±0.12%, ka guji wuce igiyoyin siginar analog a layi ɗaya da manyan layukan wutar lantarki masu ƙarfin lantarki, sannan ka tabbatar modul ɗin yana aiki cikin zangon zafin da aka ba da shawara na -20°C zuwa +60°C.

Na’urar tana ba da daidaitacciyar haɗuwa tsakanin sarrafa siginar analog mai yawa da ƙarfafa daidaiton masana’antu. Ikon ta na sarrafa siginar bipolar yana ba da damar aikace-aikace masu ci gaba kamar sa ido kan kwarara a hanyoyi biyu (bidirectional flow monitoring) ko auna matsin lamba mai tushe a sifili (center-zero pressure sensing). Bugu da ƙari, tsarin 1762 bus yana bai wa shigarwa da daidaita saituna damar gudana da sauri ta amfani da daidaitaccen software na RSLogix, wanda ke rage lokacin commissioning sosai. Ramin IP20 da ƙayyadaddun muhallin da suka ƙarfafa suna tabbatar da cewa wannan modul ɗin yana aiki da tabbas a fannoni daban-daban na masana’antu, daga sarrafa maganin ruwan shara zuwa sarrafa samar da abinci da abin sha.

Tambayoyin Fasaha (FAQs)

Q1: Zan iya haɗa siginar voltage da current a cikin modul ɗaya?
A1: Eh. Ana iya daidaita kowanne daga cikin tashoshi huɗu daban-daban don karɓar ko siginar voltage ko siginar current, wanda ke ba da cikakken sassauci a fagen shigarwa.

Q2: Mene ne mafi tsawon igiyar da ake ba da shawarar don shigarwar siginar analog?
A2: Don samun kwanciyar watsar sigina da daidaito, ana ba da shawarar a takaita tsawon igiyar zuwa ƙasa da mita 100 tare da amfani da igiyoyi masu murfi (shielded) da aka yi daidai.

Q3: Shin modul ɗin yana buƙatar wutar 24V DC ta waje?
A3: Modul ɗin yana jan mahimmin ƙarfin lantarkinsa daga 1762 bus na MicroLogix, ko da yake sensocin gefen fage na iya buƙatar tushen wutar su na musamman gwargwadon irin su.
