Remote I/O for explosion protection of paint shops
Cost-effective yet sophisticated solution with PROFINET
Field stations with Remote I/O solutions from R. STAHL have been in use in vehicle & automotive paint shops for many years. One example is a leading manufacturer in the US automotive industry. Specialised in electric vehicles, the manufacturer uses Remote I/O to control ink supply in the color mixing room that is classified as Class 1, Division 1 hazardous location acc. to US NEC 500. Although this roughly corresponds to the ATEX or IECEx classification of a Zone 1, it requires additional specific US approvals. As PROFINET technology for signal transmission has become established in the automotive industry, the decision was made to use the R. STAHL Remote I/O System IS1+. This Remote I/O system perfectly combines both explosion protection and PROFINET communication. The intrinsically safe system structure eliminates the need for "d" or "p" enclosures, ultimately saving space and cost. Risk has been decreased, and safety has been increased. All while keeping on top of explosion protection requirements.
