Based on standard Ethernet (802.3) and PoE (802.3af), Etherbus is “Every bus” because it passes any and all Ethernet message packets regardless of origin or protocol, says the vendor. Etherbus works with Modbus/TCP, Profinet, and Ethernet/IP and other fieldbus protocols as well as with PoE devices and non-PoE devices. The EB-5ES-PSE (5-port) industrial Ethernet PoE switch includes four PoE ports that automatically sense and support both PoE and non-PoE (traditional) Ethernet devices. EB-PD industrial PoE splitters convert 48VDC from PoE lines to 24VDC to power conventional (non-PoE) Ethernet devices. EB-PSE industrial PoE injectors add 48VDC power into 1 or 2 Ethernet ports to pass power and data over the same wire to Ethernet devices in the field. The EB-PS-AC48-75 and -120 industrial power supplies put out 48VDC for the Etherbus system.
