Gems® type 54800 dual channel zener barriers provide intrinsic safety with solid-state reliability. Since no explosion proof enclosures are needed for sensor wiring, these units further provide economical installation. With encapsulated construction, they are impervious to dust and moisture. They are used with instrumentation that produces an output (signal conditioners) and requires two barriers, one for each floating lead. Any non-voltage producing sensor or switch is rendered intrinsically safe for hazardous locations when properly connected to the output of these zener barriers.
