Intrinsically Safe Signal Line Protectors

Novaris slimline surge protection devices (SPDs) provide surge protection for

most twisted pair signaling schemes. Certified to be intrinsically safe Novaris

IS SPDs can be installed in the hazardous zone or the field side of the IS

barrier. This not only provides protection for the PLC or RTU I/O, it also provides

protection for the IS barrier.

IEC Ex and ATEX certified

Novaris ‘IS-’ products are certified intrinsically safe according to IEC Ex and

ATEX; the group IIC T4 certification makes it acceptable for use with all gas/

air mixtures.

Two different earthing options

With two different base options the SL protectors offer either direct earthing via

DIN rail, for the most effective, low impedance earth connection (-G base) or a

connection via GDT to the DIN rail, offering isolation under normal conditions

and equipotential bonding during a surge (-EC90 base).

Slimline pluggable modules

The plug-in design provides simple and rapid replacement and testing - no

rewiring needed. This also provides a convinient method of field equipment

isolation if required.
