摘要：
An intrinsically safe connection unit with a network interface for intrinsically safe appliances in explosion-risk areas, having a housing, a voltage supply connection, plug connection for connecting an intrinsically safe appliance via a transmission cable, and a decoupling circuit. For allowing even a multiplicity of network subscribers to be connected in the explosion-risk area with less wiring complexity, a plurality of plug connections of the same type are provided as network interface, each being preceded by a separate decoupling circuit, and the voltage supply connection builds a central feed connection with separate supply cores for each plug connection each having at least two plug contacts for data communication and at least two plug contacts for supplying power to the connectable appliances via the transmission cable. The invention relates also to a Controller and a network interface for use therewith.
