Explosive Atmospheres - Part 47: Equipment Protection by 2-Wire Intrinsically Safe Ethernet Concept (2-WISE)
Also Known As:
IEC TS 60079-47:2021 is a technical specification that provides requirements for the construction, marking, and documentation of equipment, systems, and installations that utilize the 2-Wire Intrinsically Safe Ethernet concept (2-WISE). Specifically, it focuses on the physical layer specification for 2-Wire Ethernet 10BASE-T1L as defined in IEEE 802.3cg.
The 2-WISE concept is an advanced physical layer (APL) that aims to simplify the assessment of intrinsic safety parameters for components and cabling within APL segments. It achieves this by establishing universal intrinsic safety parameter limits for APL ports based on specific hazardous area requirements and providing a clear set of rules for segment setup.
It is important to note that the construction and installation requirements for 2-WISE devices and systems specified in this technical specification are complementary to existing standards such as IEC 60079-11, IEC 60079-14, and IEC 60079-25. However, when there is a conflict between the requirements of this document and the aforementioned standards, the requirements of IEC TS 60079-47:2021 take precedence.
