What types of signaling devices make the most sense in hazardous locations?
Carter Williams, product manager, Siemens: When using control devices in a hazardous location, special precautions must be taken to ensure the signaling device used doesn’t have the potential for igniting the fiber or gases that are present during operation. Class 51 pilot devices that are rated for NEMA 7 and 9 hazardous-location applications are suitable for most hazardous environments. There are several guidelines that have been set up to guide you with your product selection based on your specific hazardous environment. You should always reference your local codes and guidelines setup in the NFPA and/or ATEX, depending on which local codes apply in your region.
