Designing Robust Isolated RS-232 Data Interfaces for Harsh Industrial Applications

Blog Post created by MOBrien Employee on Aug 1, 2012

New chip scale isolation technologies are now enabling smaller, cheaper and more reliable isolated data interfaces. For example integrating an RS-232 transceiver along with ADIs’ iCoupler and isoPower technologies enables new single chip, fully isolated RS-232 transceivers.

In my article I look at the traditional methods of implementing an isolated RS-232 interface using discrete components based on opto-couplers for signal isolation and discrete transformer for power isolation. I then show how new chip scale isolation technology, is enabling new single chip isolated RS-232 transceivers that significantly reduce design time and provide compact, reliable, low-cost, high performance solutions. I show two new fully isolated RS-232 transceivers in the article, the ADM3252E a dual channel device and the ADM3251E a single channel device.
