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.

Z-system zener barriers from Pepperl+Fuchs are directly mounted on a 35 mm DIN-Rail. Through accessories, the required grounding can be done directly on the DIN mounting rail.

• Fast mounting on the DIN-rail
• Grounding directly connected with DIN-rail
• Separation of field loop by removing the fus

Z-system zener barriers are available with high density up to 2 channels / 12,5 mm width. Variants with 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.
