Making the Upgrade: Automation Hardware Changes in Classified Hazardous Areas

Electrical installations in classified hazardous areas always present unique challenges to mitigate the possibility of an explosion. Control panels, PLC I/O and associated devices require special care and attention when selecting hardware and designing the associated electrical circuits. Whether due to equipment obsolescence or changes to the room functions and electrical classification, upgrades to automation hardware in hazardous areas may be required periodically.  Don’t make these changes though without first checking out some best practices noted in the March issue of Hixson’s From Experience newsletter.
