Efficient machine and facility operation calls for fail-safe and maintenance-friendly control voltage distribution that can be installed in a time and space-saving manner. With the new load monitoring system, the terminal blocks (previously installed separately) for distributing potential to the outputs of the electronic load monitors become an integral part of a 24 V DC control voltage distribution solution. The new combination of load monitoring and potential distribution saves time during installation, increases safety against failure and reduces the amount of space required on the terminal rail by 50 %.

Our load monitoring product range

maxGUARD is breaking new ground in control voltage distribution. The combination of load monitoring elements and potential distribution terminals saves up to 50 % space and up to 20% time with wiring work, while the flexible compatibility of numerous single-channel and four-channel variations optimises material costs. maxGUARD offers you the benefits of a modular, highly flexible system that can be optimally adapted to any application.


The IO-Link-capable load monitoring system topGUARD offers remote control options, full data transparency, and reliable protection of the 24 V system voltage. It is an outstanding supplement to the IO-LINK-capable PROtop power supplies.

  • Data transparency and remote control due to IO-Link
  • Maximal flexibility thanks to a modular system
  • Voltage-adaptive load monitoring according to Class 2
  • Time and cost savings due to an integrated distribution of potential
  • Simple migration from maxGUARD to topGUARD


Perfect for machines and systems: the fail-safe and maintenance-friendly maxGUARD system represents load monitoring and potential distribution all in one.

  • Modular, highly flexible system that can be optimally adapted to any application
  • Potential distributors with a 6.1 mm pitch ensure space-savings of up to 50 % on the rail
  • Time savings of up to 20 % due to unique cross-connectors between load monitoring and potential distribution terminals
  • Extreme ease of service during commissioning and maintenance
  • Practical disconnecting lever for simple galvanic isolation of the load circuit

Online support for Electronic Load Monitoring

We want to support you in the best possible way. This is why you’ll find all the data and information you need about our systems in the form of manuals, application notes, certificates and much more. To ensure that you have no problems operating our power supplies and that you’re always up to date, you’ll also find further information about our software updates on our website. If you have any further questions, please feel free to contact our experts at any time. We will be happy to answer your questions and help you find the ideal power supplies for your needs.

Further product families and accessories

Optimise your power supply with accessories from the Weidmüller product range. For example, by creating a redundant power supply using our modules, you can protect your switch mode power supplies from failure of the 24 VDC control voltage. We have the right product for every requirement and can also help you identify the right solution for your needs.

Redundancy and diode modules

The benefits of establishing a redundant supply are twofold: neither the failure of a switched-mode power supply nor that of an individual phase will cause the 24 V DC control voltage to fail. Each redundant branch is capable of supplying the full output load separately.
