2. Xaiv cov digital i / o chip
Cov digital i / o Chip yog cov tseem ceeb ntawm cov qauv digital i / o thiab ua haujlwm ncaj qha cuam tshuam rau cov module cov channel ntom thiab lub peev xwm. Thaum xaiv ib qho tsim nyog digital i / o chip, xav txog cov hauv qab no:
(1) channel ntom:Cov channel ntom ntawm digital i / o nti txiav txim siab cov channel ntom ntawm digital i / o module. Xaiv cov channel ntom raws li qhov yuav tsum tau ua.
(2) Cov lus tawm tswv yim / cov txiaj ntsig:Digital I / o Chips feem ntau txhawb cov kev tawm tswv yim digital thiab tawm. Qee lub chips kuj txhawb cov tswv yim analog thiab tawm, cov txee, thiab lwm yam haujlwm.
(3) Ceev:Qhov ceev ntawm cov digital I / o nti txiav txim siab cov lus teb ceev ntawm cov digital I / O Module. Xaiv ib nti nrog nrawm nrawm.
(4) Qhov Tseeb:Qhov tseeb ntawm cov digital i / o chip txiav txim siab cov teeb liab precision ntawm cov digital i / o module. Xaiv cov chips nrog cov qhab nia siab dua.
(5) nqi:Txawv cov digital i / o chips sib txawv sib txawv. Xaiv cov nti tsim nyog raws li kev ua tau tiag tiag.
3. Kev tsim kho hluav taws xob tsim
Cov Circuit Court tsim ntawm cov qauv digital i / o / o qhov kev cuam tshuam loj heev nws cov kev ua tau zoo thiab kev ruaj khov. Txhawm rau txhim kho channel ntom thiab ua haujlwm, ua kom tiav cov qauv corccuit Court los ntawm cov txheej txheem xws li:
(1) Siv siab heev - ceev cov i / o chips:Ua haujlwm siab -} ceev cov chips txhim kho module teb ceev thiab precision.
(2) Kev siv anti - kev tsim qauv cuam tshuam:Txhawm rau txhim kho kev ruaj khov, koom ua ke los tiv thaiv {{}}}}}}}}}} Kev ntsuas kev ntsuas xws li cov ntxaij lim dej thiab kev cais tawm.
(3) Thov kev ua kom zoo rau pcb)Optimized pcb tsim txo cov suab nrov thiab cuam tshuam, kev txhawb nqa module kev ua tau zoo thiab kev ntseeg tau.
4. Xaiv cov ntaub ntawv uas haum thiab qhov ntev
Digital I / O Modules yog feem ntau ntsia hauv cov txee lossis tswj cov kab hauv lossis cov ntaub ntawv xaiv thiab qhov ntev tshaj plaws. Cov ntaub ntawv ntim yuav tsum muab kev tiv thaiv kom zoo dua thiab ua kom sov dissipation los thaiv tus module puag ncig kev cuam tshuam sab nraud.
