PHD-11TC-33*
Txheej txheem cej luam
Lub teeb liab sib txuas lus ntawm PHD-11TC-33* raug nkag mus rau hauv qhov thaiv kev nyab xeeb cais, uas tuaj yeem paub txog kev sib txuas lus ob txoj kev ntawm RS-485 Ib Nrab Duplex digital teeb liab hauv thaj chaw txaus ntshai thiab thaj chaw nyab xeeb. Cov khoom no xav tau lub zog hluav taws xob ywj pheej, thiab lub zog hluav taws xob, qhov nkag thiab qhov tso zis raug cais tawm.
Hauv tsab ntawv qauv: PHD-11C-33* tus cim "*" sawv cev rau qhov hluav taws xob uas muab, thiab cov cai yog raws li nram no:
