The LCN-LLK is the plastic fiber optic coupler of the LCN bus system. It is designed as a double transmitter-receiver module and has connections for the LCN two-wire bus and the plastic fiber optic cable. Since it does not have its own processor, parameterization using the LCN system software LCN-PRO is not necessary. The plastic fiber optic coupler LCN-LLK is used to connect spatially separated individual LCN buses within an LCN segment. The range is max. 100m when using the LCN-LK cable. The LCN-LLK is used to connect individual rental, supply and building areas so that all LCN bus modules can communicate with each other.
