Direct integration of modern sensors and field devices: The Managed and Unmanaged Switches for Single Pair Ethernet and SPE-capable Media Converters enable end-to-end Ethernet communication right up to the cloud. Additional gateways or complex subsystems are not required. The devices can be used universally with all Ethernet and IP-based protocols. In addition to the transmission of data, the end devices are optimally supplied with power from the devices via Power over Dataline (PoDL). Single Pair Ethernet fulfils the requirements for a future-proof network infrastructure.
