Zener Barrier

Zener barriers – cost saving and easy mounting Ex-protection
Zener barriers provide cost saving Ex-protection for various applications in process automation systems. The amount of energy transferred to the hazardous location is limited to a safe level incapable of igniting the explosive atmosphere. Pepperl+Fuchs offers a wide product portfolio of housing and connection styles, which include DIN rail, termination board mounted, and accessories for each application.

Zener barriers have to be connected to an IS ground.
The IS grounding can be realized several ways:
Isolated from the DIN- Rail
Via an isolated DIN-Rail
Via DIN-Rail
Field replaceable fuses provide a convenient means of disconnecting or open-circuiting the instrument loop without interfering with the wiring, making commissioning and maintenance operations much easier.
