Modern technologies of galvanic separation of digital signals and their possible applications in intrinsically safe devices
Journal Title: Mining – Informatics, Automation and Electrical Engineering - Year 2015, Vol 523, Issue 3
Abstract
The article presents the reasons why the approach to separation has changed. Based on the solutions by Analog Devices and Texas Instruments, state-of-the-art technologies of galvanic separation of digital signals were presented. The authors described inductive coupling in the iCoupler technology and capacitive coupling in the ISO technology. Finally they discussed possible future applications of this kind of separation in intrinsically safe devices.
