Isolation Zones Explained
Transients follow the path of least resistance, and a tiny gap between circuit board traces is an easy path for surges to reach the delicate computer bus, bypassing expensive isolation components entirely. You'll find wide isolation zones on B&B Electronics' serial isolators such as the 485OPDR, 485OPRi & 485OPDRI-PH. If you're buying products from someone else, hold them up to the light and check the isolation zones, you might not be getting the protection that you're paying for - and need.
