NVE Corporation Product Announcement
NVE Isolators Certified Intrinsically Safe

EDEN PRAIRIE, Minn.—May 31, 2022—NVE announced today that a number of its isolated data coupler were certified under stringent ATEX and IECEx requirements for use as isolating components between intrinsically safe circuits (“IS-to-IS”) in explosive atmospheres.

Worldwide Certification
ATEX certification is given to equipment that has gone through rigorous testing outlined by European Union directives. IECEx (the International Electrotechnical Commission System for Certification to Standards Relating to Equipment for Use in Explosive Atmospheres) is accepted in many other countries, including the Unites States, China, and Japan.

NVE has both ATEX and IECEx certifications, so its isolators can meet intrinsic safety requirements almost anywhere in the world.

Non-Ignition
Certification ensures that when used within recommended entity parameters, these isolators will not become an ignition point when short circuited or if connected circuitry fails.

Widest Operating Range
Intrinsically Safe “Zones” are defined as where dust or gas can create hazardous conditions. Components in an IS zone cannot provide a source of ignition. Energy to components in IS zones must be limited, and IS-zone power supplies must be in the Safety Extra Low Voltage (SELV) range of 24 to 60 volts.

Unlike other isolation components, NVE isolators can operate over the full SELV range.

Three Intrinsically Safe Families
Three NVE isolator lines have Intrinsically Safe versions:
IL7xxVE-Series isolated datacouplers are rated at best-in-class 6 kVrms Reinforced Isolation and 1.2 kVrms Working Voltage under the stringent VDE V 0884-11 standard, providing the ultimate in rugged safety.

The IL3685V isolated RS-485 transceiver is fully compliant with PROFIBUS and RS-485 standards and designed for harsh environments. In addition to being Intrinsically Safe they have 15 kV bus ESD rating, thermal shutdown protection and are hot-plug capable. They are also rated at best-in-class 6 kVrms Reinforced Isolation and 1.2 kVrms Working Voltage.

IL0xx-Series isolators are low power and Intrinsically Safe, reducing energy usage in hazardous areas or allowing more channels for a given power budget.
The Intrinsically-Safe parts are available in various channel configurations. A total of 11 NVE part types have currently been certified.
