ZoneBarrier Network

Protects network and communications applications against induced
surges and transients

The ZoneBarrier Series is a uniquely
modular communication line interface
protection system for IT networks and
industrial communication systems. By
providing an effective barrier between
uncontrolled transient environments and your
valuable electronic systems, the ZoneBarrier
Series protects against costly system down
time and equipment failure.

The sophisticated hybrid circuitry
employed by the ZoneBarrier Series protects
your equipment without impeding normal
operation. ZoneBarrier protection components
comprise a combination of high energy Gas
Discharge Tubes with ultra-fast diodes and
Silicon Avalanche Diodes. This combination
of high quality surge protection components
gives the ZoneBarrier Series its characteristic
low let-through voltage and high, 10kA, surge
current capacity which provides excellent
protection. ZoneBarrier devices have RJ45,
terminal strip or pluggable terminal strip
connectors.

Designed for multi-port or single-port
applications the ZoneBarrier Series offers

a flexible surge protection solution that is
capable of growing with your requirements. A
ZoneBarrier module can be used as a stand­alone device, providing protection for a single
workstation, or as a building block in a surge
protection solution, as simple or as complex
as your requirements, now and in the future.

The small foot print of ZoneBarrier
modules allows a single module to be

conveniently located near to the equipment
it is protecting. Where multiple modules are
required, ZoneBarrier units can be mounted
on standard DIN rail. A DIN rail kit is also
available for 19” rack applications which can
hold up to 32 modules, providing protection
of an impressive 64 100Base-T lines while
occupying less than 5.2 inches (or a 3U
space).

All widely used network systems can
be protected by the ZoneBarrier Series.
ZoneBarrier modules are available for
100Base-T, 1,000Base-T, 10Base-2, RS232,
RS422, RS423 and others with a range of
connector types to suit all common network
applications.

Additional protection circuitry should be
provided for other parts of the network, or other
systems which may be interconnected, e.g.
incoming AC power, telephone wiring, fire and
security systems, etc. ZoneBarrier modules
are available to meet these requirements,
contact your local supplier for details.

INSTALLATION

All ZoneBarrier modules are installed in­line and are identified with “Protected” and
“Unprotected” for fail-safe installation.

DIN rail mounting (figure 2)

ZoneBarrier modules can be mounted on
any standard T-section DIN rail or on the
optional 19” DIN rail assembly. To attach the
ZoneBarrier module to the DIN rail, simply
locate the DIN rail foot of the module over on
edge of the DIN rail and then securely push
the ZoneBarrier onto the DIN rail. Note the DIN
rail must be properly grounded.

Stand-alone installation (figure 3)

To install a ZoneBarrier module as a stand­alone protector, attach an ground lead to the
supplied ring terminal and secure this with the
self tapping screw provided to the base of the
unit. Using screws (or bolts) mount the module
on any flat surface.
