Field wiring for hazardous areas
Weidmüller offers high-quality stainless steel enclosures –
assembled and certied according to customers require-
ments – for the use in hazardous areas. Fields of application
are distribution enclosures for intrinsically safe signal
circuits, distribution enclosures for power transmission and
distribution in Ex-zones, as well as eldbus distributors.
• Enclosures Klippon TB, K and POK
• Accessories like terminal blocks,
cable glands, mounting materials
• Fieldbus distributors FBCon, for intrinsically
safe applications with additional current
limitation or surge protection and stainless steel versions.
Surge protection for signal circuits
VARITECTOR gives you the best possible facility protection
to minimise plant down-time caused by surge voltages by
the use of components close to the process as well as those
in the eld or the control room.
• VARITECTOR SSC with just 6 mm modular
width gives you a space-saving solution
for use in distribution cabinets of the
control system.
• VARITECTOR SPC has a pluggable surge
protection module with a user-friendly operation
and status indication as well as fault monitoring.
Marshalling, interface units and
system cabling for control systems
Marshalling solution for efcient connection, isolation, con-
version and protection of eld signals to the control system.
• Marshalling terminals PRV with the highest wiring
density, or WMF 2.5 for the highest level of functionality
and the use of pluggable system cables.
• Interface units and PLC solutions for the efcient
interaction between the control system/PLC and the eld
connection level.
• Shield connection solutions (KLBU)
• Intrinsically safe signal conditioners for signals coming
out of the hazardous area.
Safety signal circuits
Reliable switching and protection of important process parts,
for example, the emergency shutdown of back-up systems,
with certication to the safety requirement level SIL3.
• SAFESERIES SIL3 relays for emergency shutdown
in ESD/SIS applications
• VARITECTOR surge protection for the protection
of signals with certication to the safety
requirement level SIL3.
Electrical cabinet infrastructure
Reliable components and solutions which are often used
in the control system facilities multiple times, to ensure the
power supply, communications and protection of the
electrical cabinets.
• Analogue signal conditioners
• Industrial Ethernet both active and passive
• Terminal blocks and heavy-duty connectors
• Marking systems and tools
• PRO-H power supplies for use even in hazarous areas
Power management
Weidmüller offers the most varied supply solutions to meet
its customer’s requirements for the continuous availability of
the required power supply.
• Simple parallel connectivity to increase the output power
• Diode modules to simply build redundant circuits
(true redundancy)
• Capacitor modules for the additional, short-term power
requirements in peak currents, for example, to trip circuit
breakers
• Uninterruptible power supplies (UPS) with optimised load
management and status information
• DC/DC transformers for galvanic isolation and handling of
system voltages
