BZG787 GEORGIN Zener Safety Barrier Module
The BZG787 GEORGIN is a compact, high-reliability Zener safety barrier designed to protect intrinsically safe (I.S.) circuits in hazardous industrial environments. By limiting electrical energy—both voltage and current—delivered to field devices installed in explosive atmospheres, the BZG787 GEORGIN prevents ignition risks while ensuring smooth signal transmission between field instruments and control systems.
Designed for space-saving mounting inside industrial control cabinets, the BZG787 GEORGIN barrier features a slim 13 mm enclosure profile per channel. It is suitable for installation in safe non-hazardous areas or directly within Zone 2 locations when housed inside an IP54-rated enclosure utilizing Ex nA type protection.
