Ex “ec”, Type “n”
Ex “ec”/Type “n” is a construction that enhances safety not to cause a spark, an arc or high
surface temperatures in a normal operation and also to avoid causing a spark, an arc or high
surface temperatures under defined conditions such as an overload.
A Field Control Unit (for Vnet/IP), a node unit for FIO/N-IO and an I/O module of CENTUM have
acquired ATEX Ex “ec” or ATEX Type “n”. Also, a Field Control Unit (for Vnet/IP), a node unit
for FIO/N-IO and an I/O module of CENTUM have acquired UKEX Ex “ec” or UKEX Type “n”.
And a Field Control Unit (for Vnet/IP), a node unit for FIO/N-IO, and a communication module of
CENTUM have acquired IECEx Ex “ec” or IECEx Type “n”.
An N-IO field enclosure has acquired ATEX Ex “ec”, IECEx Ex “ec”, and UKEX Ex “ec”.
This approval permits that the products above can be used in hazardous areas such as Zone 2.
