现场总线本质安全概念安全栅的研究开发

Development of fieldbus intrinsically safe conception barrier

介绍现场总线本质安全概念的内容。说明它和传统“整体”本质安全的区别,参数对比和将给应用带来的利益。介绍现场总线本质安全概念安全栅的参数设计、单元电路原理框图和安全栅开发面临的技术关键。

This paper introduces the Fieldbus Intrinsically Safe Concept, explains the difference between ＂FISCO＂ and ＂entity＂ intrinsically safe, presents a comparison between their parameters, and describes its benefits to users in the applications. The FISCO barrier parameter design, the circuit block diagram, and the key techniques for developing FISCO barrier are discussed.
