Vimpex PF-Z728 Zener Barrier - 1 Channel

Vimpex PF-Z728 Zener Barrier - 1 ChannelThe 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 alternating polarities i. e. interconnected zener diodes are employed and one side is grounded. The Zener Barrier can be used for both alternating voltage signals and direct voltage signals.Depending on the application increased or decreased intrinsic safety parameters apply for serial or parallel connection. For the detailed parameters refer to the Zener Barrier certificate. Application examples can be found in the system description of the Zener Barriers.AC Versionsuitable for Vimpex intrinsically safe products.Key Features1-channelAC versionWorking voltage 26.5 V at 10 ASeries resistance max. 327 Fuse rating 50 mADIN rail mounting
