Dab tsi yog Main Control Output
Lub ntsiab tswj qhov tso zis yog qhov tso tawm tseem ceeb ntawm qhov ntsuas kub,siv los tswj cov load ncaj qha. Nws lub hom phiaj yog txhawm rau tswj qhov kub thiab txias ntawm qhov teeb tsa tus nqi, thiab nws yog nyob rau hauv lub kaw - voj tswj kev ua tiav davhlau ya nyob twg.
Hom hom
Relay tiv tauj cov zis (passive qhuav hu, rau tswj contactors thiab kiv cua)
SSR tsav tso zis (rau tsav lub xeev relays)
Thyristor tso zis
Analog tswj cov zis: 0-10V / 4-20mA
Cov yam ntxwv tseem ceeb
Ncaj nraim tswj cov cua sov, cua txias thiab cov khoom siv actuator
Paub PID tsis siv neeg tswj raws li qhov kub thiab txias sib txawv
Target loads: contactors, solid state relays, hwj chim regulators
belongs rautswj cov zis, lub luag haujlwm rau ntawm -kev tswj qhov kub thiab txias
Transmission Output yog dab tsi
Transmission output, kuj hu ua analog retransmission tso zis, converts tusntsuas qhov ntsuas kubrau hauv cov qauv kev lag luam analog teeb liab rau cov chaw taws teeb kis.
Hom teeb liab
4-20mA / 0-20mA / 0-10V / 0-5V
Cov yam ntxwv tseem ceeb
Siv rau qhov kub thiab txias cov ntaub ntawv uploading thiab xyuas tej thaj chaw deb
Cov zis teeb liab hloov linearly nrog qhov tseeb kub
Txuas nrog PLC, HMI, recorder, data acquisition module and host computer
belongs rauteeb liab kis tau tus mob, tsuas yog rau kev sau cov ntaub ntawv, tsis koom nrog hauv - tswj chaw
Sib piv: Main Control Output vs Transmission Output
表格
| Yam khoom | Main Control tso zis | Transmission tso zis |
|---|---|---|
| Muaj nuj nqi | Tswj load thiab tswj qhov kub thiab txias | Tej thaj chaw deb kub teeb liab kis tau tus mob & cov ntaub ntawv sau |
| Ua haujlwm logic | PID kev hloov kho / rau-tso cai tswj | Linear ua raws li qhov kub thiab txias |
| Txuas ntaus ntawv | Contactor, SSR, hwj chim regulator | PLC, HMI, recorder, lub computer sab sauv |
| Hom teeb liab | Relay hu / SSR mem tes / analog tswj | Standard 4-20mA / 0-10V analog teeb liab |
| Tswj kev koom tes | Directly involved in temperature closed-loop control | Tsuas yog cov ntaub ntawv kis tau tus mob, tsis muaj kev tswj hwm |
| Daim ntawv thov | Ntawm -qhov chaw tswj qhov kub thiab txias | Centralized saib xyuas thiab tej thaj chaw deb tau |
Daim ntawv thov Scenario
Tsuas yog Main Control OutputKev ywj pheej ncu, hluav taws xob furnaces thiab khoom siv cua sov standalone; Tsuas yog hauv zos qhov ntsuas kub tsis tu ncua yog yuav tsum tau, tsis muaj cov ntaub ntawv upload xav tau.
Tsuas tso zis tawmTsis muaj kev tswj kev thauj khoom ncaj qha rau ntawm qhov chaw; kub teeb liab raug xa mus rau PLC lossis lub khoos phis tawj sab saud rau kev tswj hwm kev sib koom ua ke.
Dual Output Siv ua ke (feem ntau)
Kev tswj cov zis tseem ceeb: Paub meej qhov ntsuas kub tsis tu ncua hauv zos los ntawm kev tswj cov cua sov / cua txias
Kev xa tawm cov zis: Tshaj tawm tiag tiag-lub sijhawm kub rau PLC, kov lub vijtsam thiab lub kaw lus rau kev saib cov chaw taws teeb, cov ntaub ntawv kaw thiab kaw qhov system
Kev Xaiv & Cov Lus Cim
Yog tias koj xav tau tswj cov cua sov loads, xaiv cov qauv nroglub ntsiab tswj tso zis.
Yog tias cov ntaub ntawv kub xav tau muab tso rau hauv PLC lossis lub khoos phis tawm, thov xaivkis tau tus mob tso zis.
Cov zis kis tau tus mob yog active analog teeb liab; thov xyuam xim rau qhov zoo/tsis zoo polarity thiab siv shielded cable rau kev ncua deb.
Relay lub ntsiab tswj cov zis yog passive qhuav hu, tsis muaj polarity yuav tsum tau, sab nraud fais fab mov yog xav tau los tsim ib lub voj.
Tsis txhob sib tov ob qhov tso zis; kev sib txuas tsis ncaj ncees yuav ua rau qhov ntsuas qhov chaw nres nkoj puas.
Cov ntsiab lus
Main Control tso zis- Tswj lub nra thiab ua kom kub nyob ruaj khov hauv zos.
Transmission tso zis- Xa lub sijhawm tiag tiag -lub sijhawm ntsuas kub ntawm qhov deb rau kev saib xyuas thiab kaw cov ntaub ntawv.
Tsim nyog sib piv ntawm ob qhov kev tso tawm paub meej meej hauv zos tswj qhov kub thiab txias nrog rau kev saib xyuas cov chaw taws teeb thiab kev sib txuas tsis siv neeg.
