Conditions for using digital isolators in intrinsically safe applications
Journal Title: Mining – Informatics, Automation and Electrical Engineering - Year 2017, Vol 529, Issue 1
Abstract
This article highlights the issues related to the use of the galvanic separation of digital circuits by employing modern digital isolators in intrinsically safe applications. The authors refer to the requirements of suitable standards and directives and present their interpretation. They also identified limitations related to the use of digital isolators in intrinsically safe circuits.
