Single relay for the flush-mounting box


The LCN-R1U is a relay without its own processor for flush mounting with a potential-free changeover contact for connection to an LCN-UPP, LCN-UP24 or LCN-UPS module. This can be used in particular for switching sockets or for controlling heating actuators. The two electronic outputs of the LCN-UPP are still available.

Fields of application:

  • The relay module provides the user with an additional switching contact for each flush-mounted module.

The relay contact of the LCN-R1U is optimized for high inrush currents (contact material AgSnO). It require a minimum load of at least 20 V or 100 mA, so that no oxide layers and thus contact faults occur. The signal tone of the intelligent bus module must be switched off completely for the function of the LCN-R1U.
