Active components
Solutions for global industrial use
Ethernet technology is an established standard in ofce
communication and has existed for many years. Without it,
effective communications between equipment such as PCs,
printers, data servers, etc. would not be possible.
In recent years this technology has been expanded under
the term Industrial Ethernet and implemented in automation
systems. The common goal of both manufacturer and user is
to make the networking of automation system components
easier and more effective. To make process data and
diagnostic functions device-independent when exchanged
between network participants, all equipment in a plant
should be linked with just one bus technology.
Industrial applications, however, differ signicantly from
ofce applications. In addition, there are normally much
higher demands placed on the communication devices in
the industrial setting. These include:
• Installation conditions
• Environmental conditions
• Protocols
• Approvals
Weidmüller’s Industrial Ethernet components meet all of
these requirements as they have the properties listed below:
• Reliable (redundant) power supply for uninterrupted
network operation
• Resistance to extreme temperatures
• Immune to electromagnetically caused malfunctions
• Insensitive to vibration, shock and corrosive environments
• Conformity with various certication standards
• Longevity
These rugged devices can therefore be used world-wide in
different industries and applications.
Stable and versatile power supply inputs for
industrial applications
The redundant voltage inputs provide reliable
functionality of the whole system. If a power supply
fails, the redundant power source takes over the
energy supply. All of Weidmüller’s Industrial Ethernet
components have a wide input voltage range of at least
12 to 48 V DC (Basic Line switches 9.6 to 60 V DC).
They can also work with large uctuations in voltage.
For instance, with a rated 48 V DC input, a uctuation of
+20 % is acceptable and yet, in one of 12 V DC, a voltage
drop of up to 20 % presents no problems for the attached
devices.
