Fibre optics transceiver for plastic cabel DIN rail mounting

The LCN-LLK is the plastic LWL coupler for the LCN bus system. It is used as a double transceiver module and has connections for the LCN two-wire bus and the plastic fibre optics cable. As it does not have its own processor, programming with the LCN software LCN-PRO is not necessary.

Field of application:

  • The fibre optic LWK coupler LCN-LLG is used for the connection of separated LCN buses within an LCN segment with a max. range of 100 m when used with LCN-LK cables.
  • Single building, rented and supply areas are connected with each other so that communication among all LCN bus modules is possible.
