Advantech Corporation: Remote I/O Modules with Class I, Division 2 Certification

The modules are certified not to cause explosions if gases, vapors and liquids are present, as in any area where highly flammable substances may be produced, processed, stored, and transported. Hazardous locations are classified in three ways by the National Electrical Code (NEC): Type, Condition, and Nature. Class I locations are areas where flammable gases may be present in sufficient quantities to produce explosive or flammable mixtures. Division 2 is an environment where flammable gases, vapors, liquids, combustible dusts or ignitable fibers are not likely to exist under normal operating conditions. The company’s remote I/O modules, including repeaters, converters, and both RS-485-based and Ethernet-based remote data acquisition modules, provide ideal industrial automation, control, and measurement solutions for harsh environments and demanding applications. What’s more, with a wide operating temperature range and multiple mounting methods, the modules can be implemented across diverse applications, making the systems always connected and reliable.
