To avoid confusion in selecting explosion-proof barriers. This is a technical document comparing the structural and characteristic differences between the Zener method and the isolation method.
This document provides a clear explanation of the differences between the two representative types of intrinsic safety explosion-proof barriers: "Zener Barrier" and "Isolating Barrier." It compares their structures, grounding methods, ease of installation, costs, and introduces the characteristics and selection points for each. Additionally, it includes features of the intrinsic safety explosion-proof barrier "D5000 Series," which adopts an isolating method. [Contents] ■ Differences between Zener Barrier and Isolating Barrier ■ Comparison of grounding methods, ease of installation, and costs ■ Reasons for choosing Isolating Barrier ■ Introduction to GMI D5000 Series *For more details, please refer to the document.
