The Concept
The IP20 Solution
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 eldbus systems; but in each case, however,
there remains an interconnecting cable between the
subdistribution boards and the sensors/actuators that is
susceptible to inter ference from surrounding operations.
As has always been the case, signals are still inuenced
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
dis tributors with integrated signal-conditioning functions
providing as many functionalities as possible, even when
these are surplus to requirements).
The JACKPAC
®
solution for IP67
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 xed 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, efcient and cost-efcient
installations.
• Easy ‘Plug and Play’ installation
• Universal and versatile usage
• No additional enclosure required
• Saves time and costs
• Ideal for decentralised concepts and
plant modernisation (retrotting)
• Directly on-site at the facility
• Simple to retrot if there are malfunctions in the eld
plant
