Sizosebenza ngenhliziyo yonke ukuthuthukisa izixazululo nezinsizakalo zethu. Siphinde sithembise ukusebenzisana nabalingani bebhizinisi ukuze siphakamise ukubambisana kwethu ezingeni eliphezulu futhi sabelane ngempumelelo ndawonye. Siyakwamukela ngemfudumalo ukuthi uvakashele ifektri yethu ngobuqotho.

Imininingwane Yobuchwepheshe

Inothi: Izimpawu zokufaka zesistimu ezizenzakalelayo ziyizibonakaliso ezijwayelekile (4~20)mA; uma isignali yokufaka iyisignali yenani lokushintsha elingasebenzisi, isignali ezenzakalelayo iyisignali evulekile engasebenzisi imvamisa; uma umsebenzisi edinga ukuthi isignali ezenzakalelayo ibe yisignali evala ngokungasebenzisi imvamisa ngaphansi kwaleso simo, sicela ucacise lapho u-oda.

Izici Ezinkulu

● Ukudluliselwa kwesignali yesistimu enezintambo ezintathu; isikhwama esifakwe odongeni; ukuphazamiseka kwe-anti-RFI/EMI;

● Lo mkhiqizo unokubukeka okuhle nosayizi ophathekayo, amadivayisi amaningana angafakwa odongeni ndawonye;

● Amakhadi okulawula ayinhloko kanye namakhadi esiteshi ahlelwe ngokwehlukana kodwa anomsebenzi wokubonisa okuhambisanayo. Ngesikrini esikhulu sokubonisa se-LCD yesiShayina, ikhadi lokulawula eliyinhloko lingafeza ukusebenza kwemenyu yesiShayina kanye nokubonisa nokusebenza okusheshayo nokulula;

● Amakhadi okulawula ayinhloko kanye namakhadi esiteshi ahlelwe ngokwehlukana kodwa anomsebenzi wokubonisa okuhambisanayo. Ngesikrini esikhulu sokubonisa se-LCD yesiShayina, ikhadi lokulawula eliyinhloko lingafeza ukusebenza kwemenyu yesiShayina kanye nokubonisa nokusebenza okusheshayo nokulula;

● Izinhlobo eziningi zokukhipha zamakhadi esiteshi ziyasebenza ekuxhumaniseni amadivayisi okulawula angaphandle asendaweni. Ngokusebenzisa iphrothokholi yokuxhumana ye-MODBUS ejwayelekile, umsebenzi wokuxhumana we-RS485 ungaxhumana nekhompyutha ephethe (isb. i-DCS/PLC/EDS/RTU, njll.);

● Amakhadi esiteshi angathola isignali engu-4-20mA noma okokufaka kwesignali yenani lokushintsha futhi axhunywe kumadivayisi ahlukahlukene, kufaka phakathiisitholi segesi esivuthayos, isitholi segesi esinobuthi nesiyingozis, isitholi se-oxygens, isitholi somlilos, izinto zokubona umusi/ukushisa kanye nezinkinobho ezethusayo ngesandla, njll.;

● Londoloza amarekhodi akamuva athusayo angu-999, amarekhodi okuhluleka angu-999 kanye namarekhodi okuqala/okuvala angu-100 ukuze kuhlolwe, angeke alahleke uma kwenzeka ugesi uphela;

● Amakhadi esiteshi ane-LCD enemibala emithathu engemuva, engabonisa ngokusobala isimo esijwayelekile, ukwehluleka kanye nesimo esesabekayo;

● Ikhadi lokulawula eliyinhloko lihlanganisa imisebenzi yekhadi lokunikeza ugesi kanye nekhadi lesiteshi lesekethe eyodwa. Zonke iziteshi zingafakelwa imojuli yokuxhumana ye-HART, ekhombisa umsebenzi oqinile.

Iphaneli yokulawula

IIphaneli yokulawulaiqukethe izixhumi zokubonisa kanye nezixhumi zokusebenza zekhadi lokulawula eliyinhloko kanye namakhadi esiteshi, okuhlanganisa isikrini sokubonisa, isibonakaliso sesimo se-LED, i-alamu buzzer (efakwe ngaphakathi kwekhadi lokulawula eliyinhloko) kanye nezikhiye zokusebenza. Ikhadi lokulawula eliyinhloko linezikhiye zokusebenza eziyishumi kanti ikhadi lesiteshi linezikhiye ezintathu (bheka umdwebo olandelayo):

Ukufaka

● Yenza imigodi yokufaka engu-4 noma engu-6 (ukujula kwemigodi: ≥40mm) odongeni ngokwezidingo zobukhulu phakathi kwemigodi yokufaka (izimpawu zemigodi 1 - 6) zokufaka ipuleti lokulenga;

● Faka ibholdi yokwandisa yepulasitiki emgodini ngamunye wokufaka;

● Lungisa ipuleti elilenga odongeni bese ulibopha kuma-bolt okunweba ngezikulufo ezizithintayo ezine noma eziyisithupha (ST4.2×25);

● Lengisa izingxenye zokulenga phansi kwesilawuli endaweni A ebhodini elingezansi ukuze uqedele ukufakwa kwesilawuli.

Isixhumi esibonakalayo sangaphandle

Ikhadi lokulawula eliyinhloko lixhumanisa amasekethe angu-9 amakhadi esiteshi. Ikhadi ngalinye lesiteshi liqoqa imishini yokuxhumana yesignali yokukhipha imigqa eminingi noma i-passive switching value engu-4-20mA, njenge-GT-AEC2232bX, i-GQ-AEC2232bX, i-GT-AEC2232aT, i-AEC2338, i-GQ-AEC2232bX-P, i-AEC2338-D kanyeisitholi somlilos. Ingaxhumanisa nezinye izithumeli zokukhipha ze-4-20mA. Amasethi amabili amamojula akhelwe ngaphakathi ekhadi lokulawula eliyinhloko angafinyelela ukuxhumana okukude kwamadivayisi angaphandle (umsindo nokukhanya endaweni, sama-valve e-olenoidkanye namafeni, njll.). Amadivayisi angaphandle (isb. umsindo nokukhanya okusendaweni) angalawulwa ngamasethi amathathu eziteshi zokukhipha isignali yokudlulisela ezinikezwa yikhadi ngalinye lesiteshi. Ukuxhumana okude nohlelo lomsingathi kungenziwa ngesixhumi sokuxhumana se-RS485 ukuze uhlelo lomsingathi lukwazi ukuqapha i-AEC2392a-BS/AEC2392a-BMuhlelo lokuthola igesiezindaweni eziningana ngokujulile.

Ikhadi lokulawula eliyinhloko:

485A kanye ne-485B: Izikhumulo zokuxhumanisa ze-RS485 zokuxhumana

L, PG kanye no-N: Amatheminali kagesi e-AC220V

I-NC*(ngokuvamile ivaliwe), i-COM* (evamile) kanye ne-NO* (ngokuvamile ivuliwe): (amasethi ama-3) amatheminali okukhiphayo amasignali okulawula angaphandle okudlulisa amatheminali okukhiphayo

I-V+, i-SIN kanye ne-GND: amatheminali okufaka amasignali e-4~20mA noma inani lokushintsha elingashintshi

Ikhadi lesiteshi:

I-NC*(ngokuvamile ivaliwe), i-COM* (evamile) kanye ne-NO* (ngokuvamile ivuliwe): (amasethi ama-3) amatheminali okukhiphayo amasignali okulawula angaphandle okudlulisa amatheminali okukhiphayo

24V, i-SIN kanye ne-GND: amatheminali okufaka amasignali e-4~20mA noma inani lokushintsha elingashintshi

Uma isignali exhunyiwe iyisignali yenani lokushintsha elingasebenzisi, iziphetho ezimbili zesignali zixhunywe ku-4~20mA (IN) kanye no-+24V. Uma amandla e-DC24V ezonikezwa imishini exhunyiwe, izintambo zinjengoba ziboniswe kumdwebo wokucushwa kwesistimu.

Itheminali yangaphakathi:

I-CAH, i-CAL, i-VSS kanye ne-24V: amatheminali okuxhumana kwangaphakathi (axhunywe efektri)

Amanothi:(1) Ububanzi obukhulu obuvunyelwe bentambo yamatheminali okuxhuma bungu-2.5mm2. (2) Okuzenzakalelayo kwefektri kokukhipha kwekhadi lokulawula eliyinhloko kuyisignali yenani lokushintsha elingasebenzi.
