Acting as the head station of an electronic terminal block, the coupler converts telegrams from the higher-level fieldbus system into the bit-level signals of the internal Bus Terminals. The BK9105 features an integrated 2-channel switch with two RJ45 interfaces, enabling implementation in line topologies without requiring additional external switches.\u003c\/p\u003e\n\u003cp\u003eThis bus coupler supports up to 64 Bus Terminals directly, which can be expanded up to 255 terminals using K-bus extension technology. It handles up to 492 bytes of input data and 492 bytes of output data over EtherNet\/IP. Configuration and parameterization of the connected I\/O stations are managed via the KS2000 configuration software or through the controller using standard configuration tools. The unit is powered by a 24 V DC supply and provides internal current to the K-bus to support connected system terminals.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n
