The LCN-UPP flush-mounted module is a sensor/actuator module of the LCN bus system. It has two switchable or dimmable 230V electronic outputs. Two further outputs are simulated and not connected to the outside. The LCN-UPP also has T and I connections for accommodating additional LCN sensors and actuators. The internal operating program can be freely parameterized using the LCN system software LCN-PRO. The LCN-UPP is installed decentrally in deep switch, distribution or electronic boxes.
