Connection device for bus-subscriber on direct current-driven energy and data bus system, has energy supply unit for bus-subscriber and two-way data communication unit, where data communication unit is carried out through two-wire line

摘要

The connection device has an energy supply unit for a bus-subscriber and a two-way data communication unit, where the data communication unit is carried out through two-wire line. A coupling network is provided with a resonant circuit-1 (4,5), a rectifier (15) and a resonant circuit-2 (13,14).
