7
kV Isolator Intrinsic Safety
Certification Renewed |
|
|
|
 |
NVE aced a rigorous audit to
renew its ATEX and IECEx intrinsically safe certifications.
Our isolators are the most rugged in the industry, including up to 7 kVrms
isolation, 1200 Vrms Working Voltage, 100 teraohm isolation resistance,
and certification over the full SELV range.
Worlds Fastest Isolators
IL700-Series Isolators are the worlds fastest as well as the most rugged.
This
video proves it.
Widest SELV Range
Intrinsically Safe power supplies must be in the Safety Extra Low Voltage (SELV)
range of 24 to 60 volts. Unlike other devices, NVE isolators are certified over
the full SELV range.
Worldwide Certification
ATEX is a European certification, while IECEx is accepted in many other countries,
including the U.S., China, and Japan. NVE has both ATEX and IECEx certifications,
so the isolators can meet intrinsic safety requirements anywhere in the world.
Three Intrinsically Safe Families
Three isolator lines have Intrinsically Safe versions:
|
 |
IL7xxVE-Series
isolated datacouplers are rated for best-in-class 7 kVrms Reinforced Isolation
under the gold-standard IEC 60747-17 (VDE 0884-17):2021-10 standard.
|
 |
IL0xx-Series
isolators are low power and Intrinsically Safe, reducing energy usage in hazardous
areas or allowing more channels for a given power budget.
|
 |
IL3685VE
isolated transceivers are fully compliant with RS-485 and PROFIBUS standards and
designed for harsh environments. In addition to being Intrinsically Safe, they
have best-in-class 6 kVrms Reinforced Isolation, 15 kV bus ESD, 125 °C,
thermal shutdown protection, and hot-plug capability. And theyre the worlds
fastest isolated transceivers at 40 Mbps. |
NVE Intrinsically-Safe isolators are available in popular channel configurations:

Sensor
Interface Isolation
There are several compelling
reasons to isolate SPI sensors from microprocessors:
|
|
Safety
Isolation prevents high voltages in the sensor environment from reaching the microprocessor
and user interface.
|
|
Protection
Isolators safeguard microprocessors from ESD in the sensor environment.
|
|
Data Integrity
By eliminating ground loops and reducing the transmission of EMI noise, isolation
can significantly improve signal integrity.
|

Isolated SPI sensor interface
In this circuit, the IL7617VE
provides isolated power as well as data. Its three transmit channels and one receive
channel make it ideal for isolating SPI sensors.

NVE will be expanding
and staying put for a while.

The company extended its lease through 2031. The new lease includes funding for
an expansion to increase capacity and capabilities. |
