INTRINSICALLY SAFE ENERGY AND DATA TRANSMISSION IN AN ETHERNET NETWORK

摘要

A transmission device for the intrinsically safe transmission of data in an Ethernet network via a core pair of an Ethernet cable is disclosed. The transmission device includes a first sub-path connected to a first wire of the core pair of an Ethernet signal pair and a second sub-path connected to a second wire of the core pair of the Ethernet signal pair. Each sub-path comprises at least one current-limiting resistor and a common-mode rejection unit connected in series to the current-limiting resistor.
