Product Description
Pepperl + Fuchs Z779 2 Channel Zener Barrier is engineered for use as a safety interface between intrinsically safe and non-intrinsically safe circuits in hazardous and industrial environments. This DIN Rail mounted barrier limits the energy transferred from the safe area to the hazardous area, preventing ignition hazards by controlling voltage and current.
Designed for industrial automation, electrical signal conditioning, and process control applications, the Z779 model supports intrinsically safe thermocouples and other sensor inputs. It features dual channel operation to impede direct grounding and ensures system integrity through zener diode conduction only in fault conditions.
The device operates reliably within a temperature range of -20°C to 60°C, with a supply voltage of 27V DC and an IP20 protection rating, suitable for indoor electrical environments. Its screw terminals provide robust connections for secure installation.
The Z779 is certified under ATEX hazardous area certification and meets rigorous EN, TUV, CE, and IEC standards, making it compliant for use in Class 1, Division 1, Groups A-G environments. Typical industrial use cases include signal isolation and safe interfacing in manufacturing, process automation, and hazardous location installations.
