Qattiq holatdagi releni multimetr bilan qanday baholash mumkin
Multimetrdan umumiy foydalanish aniqlay olmasa, biz qattiq holat o'rni yaxshi va yomon aniqlashni aniqlaymiz, to'g'ri aniqlash usuli shu tarzda bo'lishi kerak.
Avvalo, biz birinchi navbatda aniqlash tugagandan so'ng qarashimiz kerak, u kirish boshqaruv terminaliga 3V dan 32V gacha sozlanishi doimiy kuchlanish manbaiga ulanishi mumkin, keyin yorug'lik chiqaradigan diyotning normal yonishi mumkinligi ko'rsatkichini kuzatishimiz kerak, keyin chiqish tomoniga e'tibor bering yukga ulanish shart emas, quvvat manbaiga ulamang.
Shu tarzda ishlash uchun ikkinchi qadam: bu vaqtda biz kirish nazorat kuchlanish UI bo'lsa, chiqish qarshilik aniqlash uchun multimeter RX1K fayl ko'rsatkich foydalanish mumkin.<2.7V, the multimeter indicates that the resistance value should be infinite, in other words, the output of the solid state relay should not conduct; we continue to increase the voltage, when the voltage increases to 3V, when the multimeter's resistance value is generally below 10 ohms, indicating that the output of the solid state relay is already conducting.
Nihoyat, uchinchi bosqich: sinovning dastlabki ikki bosqichi normal bo'lgandan so'ng, biz yuk va quvvat manbaini ulashimiz mumkin, kirish kuchlanishi 0V bo'lsa, yuk ishlamayapti; kirish kuchlanishi 5V yoki shunga o'xshash ga qo'shilsa, yuk ishlashi mumkin. Bu qattiq holat o'rni buzilmaganligini ko'rsatish uchun, aks holda qattiq holat o'rni noto'g'ri va uni ta'mirlash kerak.
