The LCN-SR6 is an intelligent six-fold relay module of the LCN bus system which does not require a separate LCN bus module. With its relays any consumers can be switched. The LCN-SR6 can be extended to eight relays with an LCN-R2H if required. As an independent bus module it has an I connection and a P connection. Thus the LCN-SR6 can be extended with additional relay blocks and LCN-BS4 current sensors.
