Function
The Zener Barrier Z728 prevents the transfer of unacceptably high energy from the safe area into the hazardous area. Pepperl+Fuchs Zener Barrier Z728
The zener diodes in the Zener Barrier are connected in the reverse direction. The breakdown voltage of the diodes is not exceeded in normal operation. If this voltage is exceeded, due to a fault in the safe area, the diodes start to conduct, causing the fuse to blow. The Zener Barrier has a positive polarity, i. e. the anodes of the zener diodes are grounded.
