Analog tswv yim

Txheej txheem cej luam

Kev tiv thaiv kev nyab xeeb ntawm kev tshawb pom sab: PHD-11TD-21, analog input thiab output, ib qho kev tawm tswv yim thiab ib qho kev tso tawm.

^ Cov kab thaiv kev sib cais tuaj yeem sib cais thiab xa cov teeb liab 4 ~ 20mA lossis DC 4 ~ 20 mA teeb liab tsim los ntawm lub transmitter hauv thaj chaw txaus ntshai mus rau thaj chaw nyab xeeb. Thaum lub transmitter yog ob-xaim los yog peb-xaim system, qhov kev ruaj ntseg barrier muab lub zog rau lub transmitter.

^ Cov khoom no xav tau 20-35VDC fais fab mov sab nraud.

^ Cov khoom no txhawb nqa HART teeb liab thiab lub tswb cuam tshuam.

* Ceeb Toom: Yog tias koj xav tau lwm yam khoom ntawm cov khoom no, thov hu rau peb cov kev pabcuam. Yog hais tias cov zis yog lwm yam tsis, nws yog qhia los ntawm tus xov tooj 9, thiab cov tsis tshwj xeeb yog qhia tom qab tus qauv tooj.

^ Piv txwv:input 2-xaim, 3-xaim los yog 4-20mA, tso zis 2 ~ 10V.

^ Qauv:PHD-11TD-29 (2-10V)

* Tsheb npav fais fab mov, saib daim ntawv txuas ntxiv kom paub meej.

PHD-12 TX-211

Ob los yog peb-xaim transmitter los yog tam sim no qhov chaw tawm tswv yim / 4 ~ 20mA tso zis 1 input 2 tso zis

Txheej txheem cej luam

PHD-12TD-211 yog ib qho kev sib cais ntawm qhov kawg kev nyab xeeb barrier tsim tshwj xeeb rau analog input thiab tso zis.

PHD-22 TX-2121

Ob los yog peb-xaim transmitter los yog tam sim no qhov chaw nkag

/ 4 ~ 20mA tso zis 2 inputs 2 outputs

Txheej txheem cej luam

Kev tiv thaiv kev nyab xeeb ntawm kev tshawb pom sab: PHD-22TD-2121, dual input thiab dual tso zis nrog analog teeb liab.

Surge Protection Type Analogue Input Isolated Safety Barrier
PHD-11TD-21+ 1 input thiab 1 output
PHD-12TD-211+ 1 input thiab 2 outputs

Cov tswv yim: ob lossis peb-xaim transmitter lossis tam sim no qhov chaw (HART digital teeb liab)
Tso zis: 4 ~ 20mA (HART digital signal)
