Protecting RS-485 interfaces against lethal electrical transients

Posted: 09 Jun 2009 ?? ?Print Version ?Bookmark and Share

Keywords:RS-485 interface? electrical transients? immunity test?

Industrial networks must operate reliably in harsh environments. Electrical over-stress transients caused by ESD, switching of inductive loads or lightning strikes will corrupt data transmission and damage bus transceivers unless effective measures are taken to diminish transient impact.

This article gives an overview of the three most commonly applied transient immunity tests and provides recommendations on how to protect network nodes against real world transients.
