Additional Certifications for Touchscreen Panels

Ross Systems and Controls (SysCon) touchscreen purged panels for Ross, Charles & Son’s mixers, blenders, and other types of equipment and processes have been certified under the standards of Underwriters Laboratories’ (UL)-698A Code and the National Fire Protection Association’s (NFPA)-496 Code. The new certifications are in addition to UL-508A (non-hazardous control panels).

The UL-698A certification involves industrial control panels designed for hazardous locations, including the use of safe barriers. NFPA-496 standards relate to purged and pressurized enclosures.

According to the company, purge systems, which are an alternative to traditional National Electrical Manufacturers Association (NEMA) standards 7 and 9 explosion proof enclosures, are suited for most hazardous locations, including class I, division I and II for gas and vapor environments as well as class II, division I and II for dust environments. Purge panel enclosures can be NEMA 4 carbon steel or NEMA 4x stainless steel depending upon regulatory or aesthetic requirements, the company reports.
