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 convenient method of field equipment isolation if required.
