Programmable logic maub los ( PLC ) lossis programmable maub los yog lub khoos phis tawj digital uas tau raug kho thiab hloov kho rau kev tswj cov txheej txheem tsim khoom, xws li cov kab sib dhos, lossis cov khoom siv neeg hlau, lossis txhua yam haujlwm uas yuav tsum muaj kev ntseeg siab, yooj yim ntawm kev ua haujlwm thiab kev kuaj xyuas kev ua txhaum.
Yog li ntawd, PLC yog dab tsi thiab nws ua haujlwm li cas?
Lub programmable logic controller yog lub khoos phis tawj tshwj xeeb siv los tswj cov tshuab thiab cov txheej txheem. Tsis zoo li tus kheej lub computer txawm tias PLC yog tsim los kom ciaj sia nyob rau hauv lub rugged industrial cua thiab yuav hloov tau yooj yim nyob rau hauv yuav ua li cas nws cuam tshuam nrog inputs thiab outputs rau lub ntiaj teb no tiag.
Tsis tas li ntawd, dab tsi yog hauv PLC? Cov PLC Feem ntau muaj CPU, thaj chaw nco, thiab cov khoom siv hluav taws xob tsim nyog kom tau txais cov ntaub ntawv nkag / tawm. Peb tuaj yeem xav txog qhov PLC los ua ib lub thawv uas muaj ntau pua lossis ntau txhiab tus sib cais relays, txee, timers thiab cov chaw khaws ntaub ntawv.
Ua li no, 4 lub ntsiab ntawm PLC yog dab tsi?
PLC Cheebtsam
- Fais fab mov.
- Input module.
- Tso zis module.
- Processor (CPU)
- Rack los yog mounting los ua ke.
- Programming unit (software)
PLC vaj huam sib luag yog dab tsi?
Programmable logic maub los ( PLC ) tswj vaj huam sib luag los yog tseem hu ua PLC Automation Vaj huam sib luag yog ib qho tseem ceeb tshaj plaws thiab muaj txiaj ntsig ntawm kev tswj hwm vaj huam sib luag . Uas yog feem ntau yog siv nyob rau hauv ntau yam ntawm hluav taws xob thiab hluav taws xob Circuit Court fittings.

Yuav ua li cas koj xaim hluav taws xob tiv thaiv hluav taws xob?
Ntxig txhua lub xaim rau hauv lub qhov tsim nyog hauv qhov chaw txais khoom tshiab thiab ceev cov ntsia hlau davhlau ya nyob twg kom ruaj ntseg. Qhwv qhov kawg ntawm cov tooj liab liab lossis ntsuab xaim (hauv av) nyob ib ncig ntawm cov ntsia hlau ntsuab thiab nruj. Maj mam thawb lub qhov hluav taws xob rov qab rau hauv lub thawv thiab ceev cov ntsia hlau mounting
Dab tsi ua rau lub qhov hluav taws xob muaj hluav taws xob tsawg?
Ib qho laj thawj uas lub qhov hluav taws xob yuav muaj lowvoltageis uas nws hnav tawm. Cov hluav taws xob hluav taws xob tuaj yeem hnav tawm tib yam li txhua yam khoom siv lossis cov khoom siv hluav taws xob.Qhov txuas tsis tu ncua thiab tshem tawm cov hlua rau hauv lub qhov hluav taws xob tuaj yeem loosen thiab hnav cov kev sib txuas
Chav hluav taws xob hloov hluav taws xob yog dab tsi?
Chav hloov. ib cheeb tsam uas muaj kev sib dhos ntawm cov khoom siv hluav taws xob rau kev tswj thiab kev tiv thaiv hluav taws xob circuits. chav hloov pauv tuaj yeem cuam tshuam rau lub substation tab sis tsuas muaj cov keyboards xwb. lub ntsiab hloov mus rau cais tawm hluav taws xob yog nyob rau hauv lub ntsiab switchroom
Puas tuaj yeem tiv thaiv hluav taws xob tiv thaiv hluav taws xob?
Surge protectors tiag tiag yuav tiv thaiv cov khoos phis tawj thiab lwm yam khoom siv hluav taws xob los ntawm lub zog hluav taws xob thiab feem ntau cov xob laim nyob deb, tab sis lawv tsis tuaj yeem tiv thaiv lub teeb pom kev ncaj qha los ntawm kev puas tsuaj rau cov khoom siv sib txuas
Puas yog txhua lub tshuab hluav taws xob muaj GFCI qhov hluav taws xob?
Duplex (ob chav) qhov hluav taws xob muaj nyob rau ntawm lub tshuab hluav taws xob nqa tau thiab txhua qhov khoom siv 120 volts. Hauv av txhaum kev tiv thaiv qhov hluav taws xob (GFCI) yog qhov tshwj xeeb ntawm qee cov qauv thiab tiv thaiv tus neeg siv los ntawm hluav taws xob shocks
