PHD-22HD-2121
Txheej txheem cej luam
Muaj kev nyab xeeb cais tawm ntawm sab ntes: PHD-22HD-2121, analog input thiab output, dual input thiab dual output.
Lub tshuab thaiv kev sib cais tuaj yeem cais thiab xa cov teeb liab 4 ~ 20mA lossis DC 4 ~ 20 mA uas lub tshuab xa xov tsim tawm hauv thaj chaw txaus ntshai mus rau thaj chaw nyab xeeb. Thaum lub tshuab xa xov yog ob-xaim lossis peb-xaim, lub tshuab thaiv kev nyab xeeb muab lub zog rau lub tshuab xa xov.
Cov khoom no xav tau kev muab hluav taws xob ywj pheej.
Cov khoom no txhawb nqa HART teeb liab thiab kev ceeb toom txiav tawm.
| Fais fab mov | 20 ~ 35VDC, kev siv hluav taws xob |
