DGA safety barrier is a main line of our DG series rail type instruments for preceding stage processing, and it is the crystallization of our rich experience in development and manufacturing of various type of safety barrier, and the latest technologies introduced from renowned foreign companies.
DGA safety barrier is a compact guide rail type instrument. It features compactness, low weight, cute appearance, and it can be flexibly and conveniently mounted.
DGA safety barrier is characterized by compact construction, high accuracy and low temperature drift, through using high performance modular circuit design and advanced SMT technology. Its reliability is remarkably enhanced, by isolating input, output and power supply from each other through electromagnetic isolation.
During mounting or power distribution, the electrified DGA safety barrier can be plugged and replaced, by which means the maintainability greatly improved.
DGA safety barrier is the related equipment of intrinsically safe instrument! identification of explosion-protection class of DGA—□□00 (ib) safety barrier is: [Exib]IICT6. <
DGA—□□00(ib) safety barrier has been tested qualified by China Quality Supervision and Test Center for Electric Equipment for Use in Explosion Atmospheres (CQSTEx, Nanyang, Henan, China), and awarded with (nationally accepted) Explosion-Protection Certificate by the center, the number of which are CNEx02.847、CNEX02.848、CNEX02.850.
According to its different function, DGA safety barriers are in four types: isolation single channel test end, single channel operation end, repeatable single channel and switching value input/output safety barrier.
As the connecting equipment between control room instrument and onsite instrument, it is widely used in process control systems of industries, such as oil, metallurgy, chemical industry and power plants, particularly in intrinsically safe systems of special industry requiring explosion protection
