Imininingwane Yezobuchwepheshe

Izici Eziyinhloko

● Isakhiwo sensimbi engu-19” esijwayelekile sekhabhinethi engu-3U esifakwe ngephaneli singavimbela ukuphazamiseka kwe-EMI/RFI. Ngenxa yomklamo ozimele wekhadi le-plug-in, amakhadi amashaneli angakhethwa, amakhadi okulawula amakhulu kanye namakhadi okuphakela amandla angasetshenziswa njengoba kudingekile ukuze kumiswe uhlelo lokuqapha igesi elinezindawo zamaphoyinti angu-1,000;

● Ikhadi lokulawula eliyinhloko libonakala ngesibonisi se-LCD sesiShayina kanye nokusebenza kwemenyu yezinhlamvu. Ingakwazi ukuqapha ukuhlushwa kwesistimu, i-alamu kanye nezimo zokwehluleka. Ingasetshenziswa futhi ukusetha nokusesha amapharamitha ahlukahlukene. Ingasetha isikhathi sesistimu, ububanzi (% LEL, ppm kanye ne-%VOL), izinhlobo ezintathu ze-alamu, ukugxilwa kwe-alamu, iphasiwedi, nokugunyazwa kokusebenza kanye nokusesha amarekhodi e-alamu namarekhodi angu-999 kanye namarekhodi okuqalisa/ukuvala ayi-100;

● Ikhadi lokulawula eliyinhloko lekhadi lokuxhumana lebhasi le-RS485, elifakwe iphrothokholi evamile ye-MODBUS, lingaxhumana namasistimu okulawula umsingathi futhi lixhume amasistimu omlilo negesi ukuze kuthuthukiswe izinga lokuhlanganisa isistimu;

● Amakhadi amashaneli angathola isignali ye-4-20mA noma okokufaka kwesignali yenani lokushintsha futhi axhunywe namadivayisi ahlukahlukene, okuhlanganisa izithoni zegesi ezivuthayo, izithonjana zegesi ezinobuthi neziyingozi, izithonjana ze-oksijini, izithonjana zomlilo, izithonjana zentuthu/ukushisa nezinkinobho ezithusayo ezenziwa ngesandla, njll.;

● Ngokunemba kwesibonisi se-LED okungu-0.000-9999, amakhadi esiteshi angakwazi ukuqapha ukugxiliswa kwemishini yangaphandle, izimo ze-alamu kanye nokuhluleka ngesikhathi sangempela futhi axhumane nekhadi lokulawula eliyinhloko. Amakhadi eziteshi nawo angasebenza ngokuzimela futhi asetshenziselwe ukusetha imingcele yezitholi. Ngakho, ukwehluleka kwekhadi lokulawula eliyinhloko noma ukwehluleka kwamanye amakhadi esiteshi ngeke kube nomthelela ekuqaphelweni kwegesi kwamakhadi esiteshi;

● Izinhlobo eziningi zokuphuma kwamakhadi amashaneli ziyasebenza ekuxhumaneni kwemishini yokulawula yangaphandle ehlukahlukene esendaweni, elungele ukuhlanganiswa kohlelo lokulawula umsingathi;

● Amakhadi okuphakela amandla ahlinzeka ngogesi we-DC24V kumadivayisi angaphakathi ekhompuyutha ebamba kanye namadivayisi asendaweni (uma kwenzeka umthamo omkhulu, sebenzisa ukunikezwa kwamandla okucisha umlilo ngenjongo ekhethekile).

I-HA1+ ne-HA2-:amatheminali okuxhuma okukhipha isignali edluliselweyo uma kwenzeka umtshina unikeza i-alamu ephezulu

I-GND kanye ne-4~20mA (OUT):(4~20) amatheminali okukhipha isignali ye-mA

GND, 4~20mA (IN) kanye +24V:amatheminali okokufaka we-(4~20) mA noma amasiginali yenani lokushintsha

Itheminali yangaphakathi: akukho msebenzi odingekayo

B futhiA: Amatheminali okuxhumana okuxhumana kwangaphakathi

I-GND ne-24V-IN:Amatheminali kagesi we-DC24
