PHD-11TC-33M
Txheej txheem cej luam
Lub teeb liab sib txuas lus ntawm PHD-11TC-33M 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. Lub voj voog muab kev faib hluav taws xob rau cov cuab yeej hauv tsev. Tus nqi hluav taws xob tuaj yeem hloov pauv los ntawm lub pob hloov sab saum toj. Txoj kev ua haujlwm tshwj xeeb tau qhia hauv daim ntawv qhia hauv qab no. Cov khoom no xav tau lub zog hluav taws xob ywj pheej, thiab lub zog hluav taws xob, kev nkag thiab tso zis raug cais tawm.
