产品介绍
"For most non-voltage-producing devices located in a hazardous area, a single zener barrier that is negative-earth-grounded can be used for intrinsic safety.","Instrumentation that produces an output (signal conditioners) usually requires two barriers, one for each \"floating\" lead. In this case, select one of the 54800 Series dual channel barriers shown here.","Any non-voltage-producing sensor or switch is rendered intrinsically safe for hazardous locations when properly connected to the output of these Zener Barriers."
特性
- 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, 54800 Series Barriers are impervious to dust and moisture
- Optional clip available for rail mounting
