Intelligent fieldbus interface

The new FieldConnex FieldBarrier adds to Pepperl+Fuch’s concept of availability. It includes 12 outputs with diagnostics and monitoring.
The FieldBarrier includes features designed to offer protection against typical fault scenarios to ensure maximum reliability. FieldConnex FieldBarriers is said to be able to detect the dynamics of faults, such as loose contacts or contact bounces. As a result, faults can be identified and isolated quickly.
The new component is the first to allow monitoring of the physical layer at each FieldBarrier output. This enables gradual changes in the installation and faults in the control room to be reported. This monitoring function ensures a high degree of transparency and fills a gap in the monitoring process as it proactively identifies maintenance requirements.
Another feature is load management. The 12 outputs start sequentially, reducing the load on the power supply from the inrush current. If the segment current reaches critical levels, automatic load-shedding of less critical nodes is activated in order to safeguard against failure of the entire segment.
