Zener Barrier, Z705, Z-System Barriers

  • 1-channel
  • DC version, positive polarity
  • Working voltage 0.9 V at 1 µA
  • Series resistance max. 18.18 Ω
  • Fuse rating 250 mA
  • DIN rail mounting

he Zener Barrier prevents the transfer of unacceptably high energy from the safe area into the hazardous area.

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.
