PHD-12TF-288
Txheej txheem cej luam
Kev tiv thaiv kev nyab xeeb ntawm kev tshawb pom sab: PHD-12TF-288, digital input thiab output, ib qho kev tawm tswv yim thiab ob qhov tso zis.
^ Cov kab thaiv kev sib cais tuaj yeem hloov pauv qhov sib thooj thiab sib txuas lus hauv thaj chaw txaus ntshai rau lub transistor tso zis teeb liab thiab xa mus rau thaj chaw nyab xeeb. Cov zis transistor nruab nrab ntawm ec yog nruab nrog ib qho kev xaiv hloov ntawm "inverted theem / ib txwm theem", ntxiv rau, muaj ib tug input teeb liab luv luv Circuit Court los yog qhib Circuit Court tswb qhia, lub Circuit Court muab rau input sensor fais fab mov.
^ Cov khoom no xav tau 20-35VDC fais fab mov sab nraud.
^ Lub teeb liab qhov taw qhia tau teeb tsa hauv lub teeb liab thiab daj los qhia txog kev ua haujlwm ntawm cov zis relay, thaum lub tswb nrov ces lub teeb liab, thaum lub sijhawm ua haujlwm lub teeb daj.
* Tsheb npav fais fab mov, thov mus saib cov ntawv txuas ntxiv kom paub meej.
