The efficient operation of machines and systems requires fail-safe and maintenance-friendly control current distributions that can be installed in a time- and space-saving manner. The new load monitoring system eliminates the need for the previously separately installed terminal blocks for potential distribution, as the outputs of the electronic load monitors become an integral part of the control current distribution. The new combination of load monitoring and potential distribution saves time during installation, increases reliability and reduces the space required on the mounting rail by 50%.
