Надежная защита RS-485: TVS, GDT, "земляная петля" и гальваническая развязка

Burned out an RS-485 port? Or are you afraid it will fail at the worst possible moment, paralyzing your entire network? That "ESD Protected" label on the IC isn't enough. In this episode of the "Upgrade" podcast, Dr. Kuznetsov and I do a full breakdown: from threat theory to real circuit designs that will save your devices. We'll analyze why your protection might not be working, even if you followed the datasheet. Learn how to properly build layered protection for industrial interfaces against ESD, EFT, Surge, and fatal design flaws.
