Pepperl + Fuchs 2 Channel Zener Barrier ATEX Certified DIN Rail Mount Z787.F

Pepperl + Fuchs Z787.F 2 Channel Zener Barrier is an ATEX certified safety barrier designed for integration in hazardous area signal conditioning systems. It provides intrinsic safety by limiting the energy transferred between safe and hazardous areas, thereby preventing ignition risks in explosive atmospheres.

This DIN rail mounted Zener barrier device incorporates dual channels, allowing independent isolation of signals with a safety current resistance of 341 ohms and a maximum safety voltage of 250 V. It utilizes screw terminals for secure electrical connections and operates reliably within a temperature range from -20°C to 60°C.

Typical applications include interfacing thermocouples and other intrinsically safe circuits in industrial process control, instrumentation, and automation systems where safety is critical. The device is designed to suppress external circuit influences and ensure safe grounding by allowing ground to be established only on fault conditions.

Constructed from high-quality materials and certified to EN, CE, TUV, and IEC standards, the Z787.F series ensures compliance and long-term dependable operation. The IP20 enclosure rating provides basic protection suitable for indoor installation within electrical control cabinets.

This device features two channels with Zener barrier technology to ensure intrinsic safety. Mountable on standard DIN rails for easy integration in control panels. Operates at a supply voltage of 27 V dc with a maximum safety current of 93 mA.

Designed with screw terminal types to secure reliable connections. IP20 rated enclosure provides protection against finger contact and limited ingress of solid objects. Operating temperature range from -20°C to 60°C suitable for varied industrial environments.

Includes safety current resistance of 341 ohms for fault protection. Certified to standards EN, CE, TUV, and IEC ensuring compliance and reliability. Manufactured in Indonesia under the Pepperl + Fuchs Z787.F series. Commonly applied in thermocouple and intrinsically safe circuit isolation barrier applications.

This Zener Barrier is essential for industries requiring safe signal transmission across hazardous and safe zones, including chemical processing, oil and gas, pharmaceuticals, and manufacturing. Its compliance with ATEX certification enables usage within explosive gas atmospheres, delivering high safety and performance standards.
