Mafotokozedwe Aukadaulo

Zindikirani: Zizindikiro zoyambira zolowera mu dongosolo ndi zizindikiro zokhazikika (4~20)mA; pamene chizindikiro cholowera ndi chizindikiro cha mtengo wosinthira, chizindikiro chokhazikika ndi chizindikiro chotseguka nthawi zonse; ngati wogwiritsa ntchito akufuna kuti chizindikiro chokhazikika chikhale chizindikiro chotseka nthawi zonse, chonde fotokozani mukamayitanitsa.

Zinthu Zazikulu

● Kutumiza chizindikiro cha makina a waya atatu; chivundikiro chomangiriridwa pakhoma; kusokoneza kwa anti-RFI/EMI;

● Katunduyu ali ndi mawonekedwe okongola komanso kukula kwake konyamulika, zipangizo zingapo zimatha kuyikidwa pamodzi pakhoma;

● Khadi lalikulu lowongolera ndi makadi a njira zimayikidwa padera koma zimakhala ndi ntchito yowonetsera yogwirizana. Ndi chophimba chachikulu cha LCD cha ku China, khadi lalikulu lowongolera limatha kugwira ntchito pa menyu yaku China komanso kuwonetsa ndi kugwiritsa ntchito mwachangu komanso mosavuta;

● Khadi lalikulu lowongolera ndi makadi a njira zimayikidwa padera koma zimakhala ndi ntchito yowonetsera yogwirizana. Ndi chophimba chachikulu cha LCD cha ku China, khadi lalikulu lowongolera limatha kugwira ntchito pa menyu yaku China komanso kuwonetsa ndi kugwiritsa ntchito mwachangu komanso mosavuta;

● Mitundu yosiyanasiyana ya ma channel card output imagwira ntchito polumikiza zida zowongolera zakunja zomwe zili pamalopo. Pogwiritsa ntchito njira yolumikizirana ya MODBUS, ntchito yolumikizirana ya RS485 imatha kulumikizana ndi kompyuta yolandira (monga DCS/PLC/EDS/RTU, ndi zina zotero);

● Makhadi a Channel amatha kulandira chizindikiro cha 4-20mA kapena chizindikiro cha switching value ndipo amatha kulumikizidwa ndi zipangizo zosiyanasiyana, kuphatikizapochowunikira mpweya woyakas, chowunikira mpweya woopsa komanso woopsas, chowunikira mpweyas, chowunikira motos, zodziwira utsi/kutentha ndi mabatani owopsa pamanja, ndi zina zotero;

● Sungani zolemba zaposachedwa kwambiri za 999, zolemba za kulephera 999 ndi zolemba 100 zoyambira/kuzimitsa kuti mufufuze, zomwe sizidzatayika ngati magetsi alephera;

● Makhadi a Channel ali ndi LCD yakumbuyo yamitundu itatu, yomwe ingasonyeze bwino momwe zinthu zilili, kulephera komanso momwe zinthu zilili zoopsa;

● Khadi lowongolera lalikulu limaphatikiza ntchito za khadi loperekera magetsi ndi khadi la njira imodzi. Ma channel onse akhoza kukhala ndi gawo lolumikizirana la HART, lomwe limasonyeza ntchito yamphamvu.

Gawo lowongolera

Thegawo lowongoleraIli ndi ma interface owonetsera ndi ma interface ogwiritsira ntchito a khadi lowongolera la master ndi makadi a channel, kuphatikiza chophimba chowonetsera, chizindikiro cha LED, buzzer ya alamu (yomwe yaikidwa mkati mwa khadi lowongolera la master) ndi makiyi ogwiritsira ntchito. Khadi lowongolera la master lili ndi makiyi khumi ogwiritsira ntchito pomwe khadi la channel lili ndi atatu (onani chithunzi chotsatirachi):

Kuyika

● Pangani mabowo anayi kapena asanu ndi limodzi (kuya kwa dzenje: ≥40mm) pakhoma malinga ndi zofunikira za kukula pakati pa mabowo oikira (zizindikiro za mabowo 1 - 6) poikira mbale yopachikira;

● Ikani bolt yowonjezera ya pulasitiki mu dzenje lililonse loyikiramo;

● Konzani mbale yopachikira pakhoma ndikuyimangirira pa mabotolo owonjezera ndi zomangira zinayi kapena zisanu ndi chimodzi zodzigwira nokha (ST4.2×25);

● Pachika zida zopachikira pansi pa chowongolera pamalo A pansi pa bolodi kuti mumalize kuyika chowongolera.

Mawonekedwe akunja

Khadi lowongolera lalikulu limalumikiza ma circuits 9 a makadi a channel. Khadi lililonse la channel limasonkhanitsa zida zolumikizirana za 4-20mA multi-line kapena passive switching value signal output, monga GT-AEC2232bX, GQ-AEC2232bX, GT-AEC2232aT, AEC2338, GQ-AEC2232bX-P, AEC2338-D detectors ndichowunikira motos. Ikhozanso kulumikiza ma transmitter ena a 4-20mA output. Ma seti awiri a ma module omangidwa mkati a master control card amatha kulumikizana kutali ndi zida zakunja (phokoso ndi kuwala komwe kuli pamalopo, smavavu a olenoidndi mafani, ndi zina zotero). Zipangizo zakunja (monga phokoso ndi kuwala komwe kuli pamalopo) zitha kuyendetsedwanso kudzera m'magawo atatu a malo otulutsira chizindikiro chotumizirana omwe amaperekedwa ndi khadi lililonse la njira. Kulumikizana kwakutali ndi makina olandirira kumatha kuchitika kudzera mu mawonekedwe olumikizirana a RS485 kuti makina olandirira athe kuyang'anira AEC2392a-BS/AEC2392a-BMnjira yodziwira mpweyam'madera angapo molimbika.

Khadi lowongolera la Master:

485A ndi 485B: Malo olumikizirana a RS485

L, PG ndi N: Malo operekera magetsi a AC220V

NC*(nthawi zambiri imatsekedwa), COM* (yamba) ndi NO* (nthawi zambiri imatsegulidwa): (maseti atatu) ma terminal otulutsa ma terminal otulutsa ma signal owongolera akunja

V+, SIN ndi GND: malo olowera a 4 ~ 20mA kapena zizindikiro zamtengo wapatali zosinthira

Khadi la njira:

NC*(nthawi zambiri imatsekedwa), COM* (yamba) ndi NO* (nthawi zambiri imatsegulidwa): (maseti atatu) ma terminal otulutsa ma terminal otulutsa ma signal owongolera akunja

24V, SIN ndi GND: malo olowera a 4 ~ 20mA kapena zizindikiro zamtengo wapatali zosinthira

Chizindikiro cholumikizidwa chikakhala chizindikiro cha mtengo wosinthira, malekezero awiri a chizindikirocho amalumikizidwa ku 4 ~ 20mA (IN) ndi + 24V. Ngati mphamvu ya DC24V iperekedwa ku chipangizo cholumikizidwacho, mawayawo ndi monga momwe asonyezedwera mu chithunzi cha kasinthidwe ka dongosolo.

Malo olumikizirana mkati:

CAH, CAL, VSS ndi 24V: malo olumikizirana olumikizirana mkati (olumikizidwa mufakitale)

Zolemba:(1) Chigawo chachikulu cha waya chomwe chiloledwa pa malo olumikizira ndi 2.5mm2. (2) Choyambira cha relay output ya khadi lolamulira la master ndi chizindikiro cha mtengo wosinthira passive.
