Function & Operation
The Zener Barrier prevents the transfer of unacceptably high energy from safe areas into hazardous areas. Zener diodes in the barrier are connected in reverse direction, with the breakdown voltage not exceeded during normal operation. If voltage exceeds safe limits due to faults in the safe area, the diodes conduct and cause the fuse to blow, ensuring safety.
Key Features
- Alternating polarities with interconnected zener diodes
- One side grounded for enhanced safety
- Compatible with both alternating voltage and direct voltage signals
- Intrinsic safety parameters vary based on application requirements
Application Note: For detailed intrinsic safety parameters and application examples, refer to the Zener Barrier certificate and system description documentation.
