PHD-11TD-21

Txheej txheem cej luam

Kev thaiv kev nyab xeeb cais tawm ntawm sab nrhiav pom: PHD-11TD-21, analog input thiab output, ib qho input thiab ib qho output.

^ Lub thaiv kev cais tawm tuaj yeem cais thiab xa cov teeb liab 4 ~ 20mA lossis DC 4 ~ 20 mA uas lub transmitter tsim tawm hauv thaj chaw txaus ntshai mus rau thaj chaw nyab xeeb. Thaum lub transmitter yog ob-xaim lossis peb-xaim system, lub thaiv kev nyab xeeb muab lub zog rau lub transmitter.

^ Cov khoom no xav tau lub hwj chim sab nraud 20-35VDC.

^ Cov khoom no txhawb nqa HART teeb liab thiab lub tswb ceeb toom txiav.

Lub analog input isolated kev nyab xeeb barrier muab lub zog cais tawmmuab rau ob - thiab peb txoj hlua xa xov hauv thaj chaw muaj kev phom sij.

Lub teeb liab 4 ~ 20mA uas lub transmitter lossis qhov chaw tam sim no tsim tawm yog xa los ntawm thaj chaw txaus ntshai mus rau qhov chaw tso zis hauv thaj chaw nyab xeeb, yog li tsav lub nra hnyav hauv thaj chaw nyab xeeb. Rau ob - lossis peb lub xov hlau transmitters lossis cov teeb liab tam sim no, qhov kev nyab xeeb no txhawb nqa kev sib txuas lus bidirectional ntawm Hart digital teeb liab superimposed rau ntawm 4 ~ 20mA teeb liab thiab muaj lub tswb ceeb toom tawg hlau.

Cov khoom no xav tau lub hwj chim ywj pheej, nrog rau lub hwj chim cais, cov tswv yim, thiab cov zis.
