Pepperl + Fuchs 2 Channel Zener Barrier, DIN Rail Mount, ATEX Certified, 13.6V AC, 250V Maximum Safety Voltage Z965

Pepperl + Fuchs Z965 2 Channel Zener Barrier is a high-quality device designed for use as a safety interface between intrinsically safe and non-intrinsically safe electrical circuits in hazardous areas. It is mounted on a DIN rail, making installation convenient and standardized for industrial control panels. The product carries ATEX hazardous area certification ensuring compliance for use in explosive atmospheres.

Manufactured from robust Makrolon® material, this dual channel barrier effectively prevents direct grounding of intrinsically safe circuits by allowing grounding only during a fault when the Zener diodes conduct. This design suppresses external circuit influences, providing enhanced protection for sensitive measuring devices such as thermocouples.

The Z965 model features a supply voltage of 13.6V AC, a maximum safety voltage rating of 250V, and a maximum safety current of 153mA, with a safety current resistance of 115Ω. These parameters ensure that energy transfer to hazardous areas is strictly limited to prevent ignition risks.

Operating temperature ranges from -20°C to 60°C, making the barrier adaptable to various industrial environments. The unit comes with screw terminal types that provide secure and reliable connection points for wiring and instrumentation.

Additional safety and quality certifications include compliance with EN, TUV, IEC, and CE standards, providing assurance for demanding industrial and automation applications including process control, water treatment, pharmaceutical manufacturing, and petrochemical plants.

The unit features dual channel safety barrier functionality for effective energy limitation. Constructed with Makrolon® for durable insulation and electrical signal conduction. Suitable for hazardous area certification ATEX standards compliance.

Maximum safety voltage is 250V with a supply voltage of 13.6V AC. Operating temperature range is from -20°C to 60°C ensuring versatility in many environments. Screw terminal type facilitates secure wiring connections. Provides IP20 ingress protection suitable for indoor industrial environments.

Typical applications include thermocouple circuits requiring intrinsically safe isolation. Safety current resistance of 115Ω and maximum safety current of 153mA protect circuits. Compliant with EN, TUV, IEC, CE standards for international reliability.

This product is ideal for engineers and maintenance professionals requiring safe, certified barriers in instrumentation and control applications requiring intrinsic safety measures. The Z965 provides peace of mind with reliable, proven performance in safety barrier technology.
