Optical RS-232 isolators to suit almost any application Our RS-232 optical isolators are ideally suited for many applications - from "control panel" installations requiring DIN Rail mounting to "in-line" or "bump in the cable" installations found in laboratory or retail systems. They provide 2 kV of isolation to protect your equipment as well as a variety of connector options. If you require extended temperature ranges and extra rugged construction, our industrial products will fit the bill. They have advanced EMC and emissions specifications that run the gamut from light industrial EN 61000-6-1 to heavy industrial EN 61000-6-2 with IEEE 1613. We also offer versions with UL 508 and UL Class 1 Division 2. Check out the specs on each product and select the optical isolator that is best suited for your needs.
