PLCs tuaj yeem muab faib ua peb pawg hauv qab no:
(1) Compact PLC
Lub compact PLC sib xyaw ua ke tag nrho cov khoom sib xyaws -xws li lub hwj chim mov, CPU, thiab cov tswv yim / tso zis interfaces - rau hauv ib lub chassis. Nws yog tus cwj pwm los ntawm nws cov qauv compact, lub cev me me, thiab tus nqi qis.
(2) Modular PLC
Lub modular PLC tsim txhua qhov ntawm PLC cov khoom sib xyaw ua ke sib cais, sib txawv module-xws li CPU modules, input/output modules, power supply module (qee zaus ua ke rau hauv CPU module), thiab ntau yam tshwj xeeb muaj nuj nqi modules.
(3) Stackable PLC
Los ntawm kev sib txuas cov yam ntxwv ntawm ob qho tib si compact thiab modular PLCs, yog li -hu ua stackable PLC yog tsim. Nyob rau hauv ib lub stackable PLC, cov khoom xws li CPU, fais fab mov, thiab input/output interfaces kuj muaj xws li ywj siab modules; Txawm li cas los xij, lawv muaj kev sib txuas ntawm cov kab hluav taws xob, thiab cov khoom siv ntawm tus kheej tuaj yeem raug muab tso rau ntawm ib qho ntawm lwm tus. Qhov kev tsim no tsis tsuas yog tso cai rau kev hloov pauv ntawm cov txheej txheem kev teeb tsa tab sis kuj tseem ua rau kev tsim cov txheej txheem compact heev.
