Iinkcukacha zobugcisa

Phawula: Imiqondiso yokufaka inkqubo emiselweyo ziimpawu eziqhelekileyo (4~20)mA; xa isignali yokufaka iyisignali yexabiso lokutshintsha elingasebenziyo, isignali emiselweyo yisignali evulekileyo engasebenziyo; ukuba umsebenzisi ufuna ukuba isignali emiselweyo ibe yisignali evaliweyo engasebenziyo phantsi kwemeko enjalo, nceda ucacise xa uodola.

Iimpawu eziphambili

● Ukuhanjiswa kwesignali yenkqubo enamacingo amathathu; isiciko esifakwe eludongeni; ukuphazamiseka kwe-anti-RFI/EMI;

● Le mveliso inembonakalo entle kwaye inobukhulu obuphathekayo, izixhobo ezininzi zinokuxhonywa eludongeni kunye;

● Ikhadi lolawulo oluphambili kunye namakhadi etshaneli abekwe ngokwahlukeneyo kodwa anomsebenzi wokubonisa ngokuhambelanayo. Ngesikrini esikhulu se-LCD yesiTshayina, ikhadi lolawulo oluphambili linokwenza imenyu yesiTshayina isebenze ngokukhawuleza nangokulula;

● Ikhadi lolawulo oluphambili kunye namakhadi etshaneli abekwe ngokwahlukeneyo kodwa anomsebenzi wokubonisa ngokuhambelanayo. Ngesikrini esikhulu se-LCD yesiTshayina, ikhadi lolawulo oluphambili linokwenza imenyu yesiTshayina isebenze ngokukhawuleza nangokulula;

● Iintlobo ezininzi zemveliso zamakhadi etshaneli ziyasebenza ekunxibelelaniseni izixhobo zolawulo lwangaphandle kwindawo. Ngokusebenzisa iprotocol yonxibelelwano yeMODBUS eqhelekileyo, umsebenzi wonxibelelwano we-RS485 unokunxibelelana nekhompyutha ephetheyo (umz. i-DCS/PLC/EDS/RTU, njl.njl.);

● Amakhadi etshaneli angafumana isignali ye-4-20mA okanye igalelo lesignali yexabiso lokutshintsha aze aqhagamshelwe kwizixhobo ezahlukeneyo, kuqukaisixhobo sokubona igesi etshayos, isixhobo sokufumanisa igesi esinobungozi nesinobungozis, isixhobo sokubona ioksijinis, isixhobo sokubona ilangatyes, izixhobo zokuvavanyela umsi/ubushushu kunye namaqhosha abangela uloyiko ngesandla, njl. njl.;

● Gcina iirekhodi zamva nje eziyi-999 ezixhalabisayo, iirekhodi zokusilela eziyi-999 kunye neerekhodi zokuqalisa/zokuvala eziyi-100 ukuze zihlolwe, ezingayi kulahleka xa umbane ucimile;

● Amakhadi esiteshi ane-LCD enemibala emithathu engasemva, enokubonisa ngokucacileyo imeko eqhelekileyo, ukusilela kunye nemeko eyoyikisayo;

● Ikhadi lolawulo eliyintloko lidibanisa imisebenzi yekhadi lombane kunye nekhadi letshaneli yesekethe enye. Zonke iitshaneli zinokuxhotyiswa ngemodyuli yonxibelelwano ye-HART, ebonisa umsebenzi oqinileyo.

Iphaneli yokulawula

Iiphaneli yokulawulaiqulethe iindawo zokubonisa kunye neendawo zokusebenza zekhadi lokulawula eliyintloko kunye namakhadi etshaneli, kubandakanya isikrini sokubonisa, isalathisi sesimo se-LED, i-alamu ye-alamu (efakwe ngaphakathi kwekhadi lokulawula eliyintloko) kunye namaqhosha okusebenza. Ikhadi lokulawula eliyintloko linezitshixo zokusebenza ezilishumi ngelixa ikhadi letshaneli linezintathu (jonga umzobo olandelayo):

Ukufakelwa

● Yenza imingxunya emi-4 okanye emi-6 yokufakela (ubunzulu bemingxunya: ≥40mm) eludongeni ngokweemfuno zobukhulu phakathi kwemingxunya yokufakela (iimpawu zemingxunya 1 - 6) yokufakela ipleyiti yokuxhoma;

● Faka ibholthi yokwandisa yeplastiki kumngxuma ngamnye wokufaka;

● Lungisa ipleyiti yokuxhoma eludongeni uze uyibophelele kwiibholiti zokwandisa ngezikrufu ezi-4 okanye ezi-6 zokuzicofa (ST4.2×25);

● Xhoma iindawo zokuxhoma ezantsi kwesilawuli kwindawo A ebhodini esezantsi ukuze ugqibezele ukuxhoma kwesilawuli.

Ujongano lwangaphandle

Ikhadi lolawulo eliyintloko lidibanisa iisekethe ezili-9 zamakhadi etshaneli. Ikhadi ngalinye letshaneli liqokelela izixhobo zonxibelelwano ze-4-20mA ezinemigca emininzi okanye ezitshintshayo zexabiso elingasebenziyo, ezifana ne-GT-AEC2232bX, GQ-AEC2232bX, GT-AEC2232aT, AEC2338, GQ-AEC2232bX-P, AEC2338-D detectors kunyeisixhobo sokubona ilangatyes. Ingadibanisa nezinye izithumeli ze-output ze-4-20mA. Iiseti ezimbini zeemodyuli ezakhelwe ngaphakathi zekhadi lolawulo eliyintloko zinokufezekisa unxibelelwano olukude lwezixhobo zangaphandle (isandi esikwindawo kunye nokukhanya, siivalvu ze-olenoidkunye neefeni, njl.njl.). Izixhobo zangaphandle (umz. isandi esikwindawo kunye nokukhanya) zinokulawulwa ngeeseti ezintathu zeetheminali zokukhupha isignali yerelay ezibonelelwa yikhadi ngalinye letshaneli. Unxibelelwano olukude nenkqubo yehost lungenziwa nge-interface yonxibelelwano ye-RS485 ukuze inkqubo yehost ikwazi ukujonga i-AEC2392a-BS/AEC2392a-BM.inkqubo yokubhaqwa kwegesikwiindawo ezininzi ngokunzulu.

Ikhadi lolawulo eliyiNtloko:

485A kunye ne-485B: Izitishi zoqhagamshelo lwe-RS485 zonxibelelwano

L, PG kunye no-N: Izitishi zombane ze-AC220V

I-NC*(idla ngokuvalwa), i-COM* (eqhelekileyo) kunye ne-NO* (idla ngokuvula): (Iiseti ezi-3) iiterminal zemveliso zesignali zolawulo lwangaphandle ezithunyelwayo iiterminal zemveliso

V+, SIN kunye ne-GND: iiterminal zokufaka ze-4~20mA okanye iimpawu zexabiso lokutshintsha ezingashukumiyo

Ikhadi letshaneli:

I-NC*(idla ngokuvalwa), i-COM* (eqhelekileyo) kunye ne-NO* (idla ngokuvula): (Iiseti ezi-3) iiterminal zemveliso zesignali zolawulo lwangaphandle ezithunyelwayo iiterminal zemveliso

24V, SIN kunye ne-GND: iiterminal zokufaka ze-4~20mA okanye iimpawu zexabiso lokutshintsha ezingashukumiyo

Xa isignali eqhagamshelweyo iyisignali yexabiso lokutshintsha elingasebenziyo, iziphelo ezimbini zesignali ziqhagamshelwe kwi-4 ~ 20mA (IN) kunye ne- + 24V. Ukuba amandla e-DC24V aza kunikezelwa kwisixhobo esiqhagamshelweyo, intambo injengoko kubonisiwe kwidayagram yoqwalaselo lwenkqubo.

Isiphelo sangaphakathi:

I-CAH, i-CAL, i-VSS kunye ne-24V: iiterminal zonxibelelwano lwangaphakathi (eziqhagamshelwe efektri)

Amanqaku:(1) Ububanzi bentambo obuphezulu obuvumelekileyo kwiitheminali zoqhagamshelo yi-2.5mm2. (2) Umlinganiselo omiselweyo wemveliso yekhadi lolawulo eliyintloko yisignali yexabiso lokutshintsha ngaphandle.
