摘要

Intrinsically safe connection unit with network interface for intrinsically safe devices in potentially explosive areas, with a housing (14), with a voltage supply connection (12) on the housing, with at least one plug connection (11) on the housing for connecting a transmission cable for an intrinsically safe device on the connection unit, and with a decoupling circuit arranged upstream of the at least one plug connection (11) and arranged in the housing (14), characterized in that a plurality of similar, electrically conductive plug connections (11A, 11B) are provided on the housing (14) as network interface connections, each of which A separate decoupling circuit is connected upstream, and that the voltage supply connection (12) on the housing is designed as a central feed connection with separate supply wires (13A, 13B, 13C) for each plug connection (11A, 11B, 11C), each plug connection (11) having at least two plug contacts ( 21) f for data communication and at least two to the associated V (22) for power supply of the connectable devices via the transmission cable.
