Pepperl + Fuchs 2 Channel Zener Barrier, ATEX Certified, DIN Rail Mount Z778

Pepperl + Fuchs Z778 2 Channel Zener Barrier is an ATEX-certified safety device designed for use in hazardous areas to ensure intrinsic safety by limiting energy transfer between safe and hazardous circuits. This dual channel barrier connects intrinsically safe equipment such as thermocouples or sensors to non-intrinsically safe systems while preventing dangerous fault conditions by impeding direct grounding unless diode conduction occurs.

The barrier utilizes high-quality Makrolon® housing material and features a DIN Rail mount type that simplifies installation within industrial electrical panels. It has screw terminals for secure and reliable wiring connections. The device operates at a supply voltage of 27V dc, offering a maximum safety current of 46mA and a safety current resistance of 646Ω, making it suitable for sensitive instrumentation protection.

With an IP20 rating, the Z778 barrier is protected against solid object ingress but designed primarily for indoor use. It operates reliably within temperatures from -20°C up to 60°C, suitable for various industrial environments. The product complies with relevant international standards including EN, CE, TUV, and IEC, ensuring dependable performance and user safety. Manufactured in Indonesia, this safety barrier is customized for demanding applications in electrical automation and signal conditioning where hazardous area certification is essential.
