Surge protection for data interfaces
The principles of data transmission
Ring networks
Four-wire systems
The computers or data terminals are all
connected to each other like a chain by
means of, for example, coaxial cable.
In this case the data is passed on
from one data terminal to the next.
Therefore, the entire ring is always
under load. The advantage of the ring
network is that it can cover a larger
area than a star n
­ etwork because the
length of the transmission path is
only ever the distance ­between two
adjacent data terminals.
This is the current standard for the
­majority of corporate data networks.
Two wires are used for transmitting
data and two for receiving. These
cables are well shielded and can
transmit data with ­frequencies of up
to 500 MHz over ­distances of up to
100 m.

Surge protection fundamentals for data signals
“Data transmission” is the name
given to the sending of characters,
numbers, ­statuses and measurements
between ­different, decentralised units.
­Decentralised units are, for example,
­controls, computers, measuring
sensors, actuators, etc. One unit
transmits the ­data, the second unit
receives it. This ­corresponds to the
simplest method of data transmission.
It is often necessary for one unit to
receive data and then send an “answer”
back to the other unit. Two data lines
in a back-to-back arrangement are
required for this, or data lines are
combined by providing each end of the
data line with a transmitter and receiver.
Structures and properties of
networks
There are various options for networking
data terminals. We distinguish between
star, ring, point-to-point and bus
networks.
Star networks
The main unit is located in the centre.
The individual data lines then radiate
out from this centre to the individual
terminals. In this system all data
terminals are ­connected to the central
terminal via their own cable.
D.2
Point-to-point networks
These are basically networks between
two data terminals that are connected
directly with each other, e.g. an RS 232
or RS 422 link.
Bus networks
These are networks based on the
parallel connection of modules. All
components operate on one and the
same line. ­Therefore, only two/four
wires are required for the data bus. If
bus cabling includes branches, then
we call that a tree ­structure. Every bus
system includes a bus controller that
issues “transmission ­licences” to the
individual data terminals.
Transmission media
In order to be able to send any data at
all, data lines are necessary:
Coaxial cable
Sending data via coaxial cables is a
rather old technique. This method is
too slow and inflexible and only a few
businesses are still using such systems.
Speeds of up to 12 Mbps are no longer
adequate these days. Over longer
distances, ­modern fibre-optic cables
have been replacing this technology;
these can transmit ­several hundred
Mbps.
Serial interfaces
A serial interface operates with 8 data
bits (1 byte). A start bit (low bit) is
always sent before the output of a byte,
and one or two stop bits (high bits)
are appended to the end of the byte.
This encryption is ­critical for the data
receiver as it can then detect where
each data byte begins and ends. Serial
interfaces frequently operate with
+5 V (logical 1) and 0 V (logical 0).
Advantage: less cabling (only 3 wires).
Disadvantage: slow data transmission.
Two- and three-wire systems
Data transmissions requiring relatively
low transmission rates can make use
of ­two-wire systems. For example, an
ISDN system acting as an exchange
line to a building requires only two
wires.
However, there are bus systems which
also require only two or three wires.

The Concept
The IP20 Solution
The JACKPAC® solution for IP67
Until now, all signal conditioning tasks were carried out by
­modules designed to IP20. For their own protection, these
need to be installed in central switchgear cabinets.
However, decentralised solutions that do not require large
switchgear cabinets are increasingly being sought for use
in modern-day industrial automation technology.
It is true that shielded signals can be fed to the machinery
via powerful fieldbus systems; but in each case, however,
there remains an interconnecting cable between the
subdistribution boards and the sensors/actuators that is
susceptible to inter­ference from surrounding operations.
As has always been the case, signals are still influenced
by overvoltages and earth loops; interference pulses are
superimposed on sensor signals and malfunctions can be
initiated.
The result is that signal conditioning modules sealed to IP20
require terminal boxes, such as switchgear cabinets, or even
cost-intensive special solutions (for example, sensor-actuator
dis­tributors with integrated signal-conditioning functions
providing as many functionalities as possible, even when
these are surplus to requirements).
By introducing JACKPAC®, the M12/RJ45 signal box
for Ethernet Cat. 6 with a high-protection rating of IP67,
Weidmüller now has a modular, versatile strategy that makes
it possible to condition signals in an industrial environment.
Requiring no additional ­enclosure, these modules can be
installed directly on the ­machine, in the production plant,
conveyor system or within a process.
The M12 connector, which is standardised all over the world,
makes it possible to integrate the JACKPAC® at any point in
the sensor-actuator cabling. The fixed pin assignment means
it is easy to install and is protected against polarity reversal.
This versatility really comes into its own when an installation
needs to be altered or modernised, simply because no
additional enclosures or cabling are required.
By providing this high degree of protection and versatility,
JACKPAC® renders possible innovative automation
concepts based on decentralised applications – without
large control ­cabinets or small distribution boards –
for consistent, transparent, efficient and cost-efficient
installations.

Installation instructions for data interfaces
Lightning and surge protection
for data interfaces
Installation instructions for data interfaces
The supply and earth lines of the protective modules should
be kept short in order to achieve optimum protection for the
data terminals.
Likewise, the transmission paths should also be kept as short
as possible because the longer the line, the greater is the
chance of interference having an effect.
Inserting surge protection increases the attenuation of the
line and so changes the signal-to-noise ratio.
Installation position
Protective modules are frequently installed at both ends of
the line.
It is important to ensure that protected and unprotected
lines are routed separately. Further, there should be some
clearance between power lines and data lines. A common
cable duct must be subdivided with metal partitions.
D
Shielded lines for data interfaces
Systems involving several buildings should be designed with
cable shielding capable of carrying current. These data lines
­often have two shields: one for carrying transient currents,
the other as protection against coupled interference.
Circuit concepts
High transmission frequencies place greater demands on
­surge protection in protective circuits for data interfaces. Gas
discharge tubes are frequently the sole means of protection
in these cases. However, the disadvantage of this is that the
­protection level is very high. Lower protection levels can be
attained at high transmission frequencies by using special
low-capacity suppressor diodes.
