Txheej txheem cej luam:
- Abb ai 845 3} bse023675r1 analog cov tswv yim module rau ib qho lossis redundant cov ntawv thov. Tus qauv muaj 8 channel. Txhua tus channel tuaj yeem yog tus qauv hluav taws xob lossis cov tswv yim tam sim no thaum mtu tu844 lossis siv tau, thaum lwm tus MTus tau siv txhua channel ua voltage los yog cov nkag tshiab.
- Cov khoom siv hluav taws xob thiab cov tswv yim tam sim no muaj peev xwm tiv thaiv cov kev txhawb nqa ntawm tsawg kawg yog 11 v DC Lub tswv yim tsis kam tshaj yog 250 Ohm.
- Cov qauv hloov kho sab nraud Hart cov khoom siv hloov kho rau txhua tus channel. Qhov no ntxiv qhov kev txuas yooj yim los faib cov khoom rau 2- xaim lossis {1} hlau transmitters. Lub tshuab xa hluav taws xob muaj kev saib xyuas thiab kev txwv tam sim no.
Ntsia & Nta:
- {{{{{0} channel analog cov tswv yim: 0 ... v.
- HART kev pab sib txuas lus: ua rau HART QROCOL sib txuas lus sib txuas lus rau ntse teb cov khoom siv, cia rau kev kuaj mob thiab kev teeb tsa.
- Ib leeg lossis kev ua haujlwm tsis zoo: tuaj yeem teeb tsa rau ib qho kev ua haujlwm ib leeg lossis kev ua haujlwm.
- Kev Rho Tawm: 1 pab pawg ntawm 8 channel yog cais los ntawm cov av, kom muaj suab nrov thiab kos npe rau kev ncaj ncees.
- Cov khoom siv xa tawm tam sim no: txhua channel suav nrog cov khoom siv xa tawm tam sim no, kev tiv thaiv cov khoom sib txuas los ntawm cov xwm txheej overcurrent.
Cov lus qhia tshwj xeeb:
- Kev daws teeb meem: 12 lub me me, muab cov tshuaj ntsuas analog-rau-digital hloov dua tshiab rau kev ntsuas yog qhov tseeb.
- Cov tswv yim impedance: 10 mω rau voltage inputs, 250 ω rau cov tswv yim tam sim no
- Kev rho tawm: Pab pawg cais cais los ntawm hauv av, ua kom muaj kev nyab xeeb thiab cuam tshuam cov hluav taws xob.
- Raws li / tshaj li qhov ntau: {{0}}}}}}} ma thiab {8}} v inps
- Qhov kub qhuav hluav taws xob: ntau tshaj 50 ppm / degree, txo qhov cuam tshuam txog qhov kev sib txawv kub ntawm kev ua haujlwm module.
- Cov lus tawm lim (lub sijhawm nce 0-90%): 290 ms, cia rau cov lus teb du los hloov cov cim qhia.
- Hloov tshiab lub sijhawm: 10 ms, ua kom cov ntaub ntawv ceev ceev tau txais thiab ua.
Cov Khoom Siv Hluav Taws Xob Kev Nyab Xeeb:
En 61010-1: Yuav tsum muaj kev nyab xeeb rau cov khoom siv hluav taws xob rau kev ntsuas, kev tswj hwm, thiab kev kuaj siv.
Ul 61010-1: UL qauv rau kev nyab xeeb ntawm ntsuas hluav taws xob, tswj, thiab kuaj cov khoom siv kuaj.
