Intshayelelo kwi-4-20 mA Output

1. Yintoni imveliso ye-4-20 mA
I-4-20 mA sisignali yangoku ye-analog esemgangathweni esetyenziswa kakhulu kwizixhobo zoshishino, ezifana neemitha zamanqanaba, iimitha zokuhamba, ii-transmitters zoxinzelelo, njl.
I-4 mA imele ixabiso eliphantsi le-0%
I-20 mA imele ixabiso eliphezulu le-100%
2. Iingenelo ze-4-20 mA
Amandla okulwa nokuphazamiseka okunamandla, afanelekileyo ekudluliseleni umgama omde
Ayichaphazeleki kangako kukuxhathisa intambo kunye nokuhla kwevolthi
Kulula ukubona ukwaphuka kwentambo (isignali < 4 mA ithetha ukuba kukho ingxaki)
Iyahambelana nee-PLC ezininzi, ii-DCS, iirekhoda kunye neenkqubo zolawulo
Izinzile kwaye ithembekile kwiindawo zoshishino ezinzima
3. Usetyenziso oluqhelekileyo
Dlulisa amaxabiso alinganisiweyo (inqanaba, ukuhamba, uxinzelelo, ubushushu)
Qhagamshela kwiinkqubo zolawulo ukuze ubeke esweni kwaye ulawule
Isetyenziswa kwizixhobo ezahlukeneyo zentsimi yemizi-mveliso
Ifanelekile kwi-oyile, unyango lwamanzi, iikhemikhali, umbane kunye nezinye izimboni
