Marketing Information

IC485AI, the Isolated Converter, is a bi-directional converter that transparently converts RS-232 signals to RS-422/RS-485 signals (and vice versa), thus permitting the creation of reliable long distance communication systems using standard computer hardware.

IC485AI provides point-to-point, multi-drop, and simplex operations over 4000 feet. Designed with built-in optocouplers for exceptional signal isolation, plus transformers for excellent power isolation, this extremely reliable isolated converter enhances the quality of the data communication. At the same time, it protects your equipment from electrical surges of up to 2000 Volts.
