Light Circuit

When planning the lighting, consider the number, function, and type of lights to be used. It is recommended to mark the individual lighting circuits on a floor plan and specify whether each circuit should be switchable or dimmable. The type and number of lights in each circuit determine which modules are required.

For dimmable lighting circuits, the Schrack Smart Building Automation Dimming Module "L1424" is used. Each module can control two lighting circuits. An appropriate external dimmer is also required for each dimmable lighting circuit, depending on the type of light source, for example an Eltako SUD12 1-10 V universal dimmer. The Dimming Module "L1424" controls the external dimmer via 0-10 V or 1-10 V. The digital output of the module can be used to switch the external dimmer or an intermediate relay on and off.

For switchable lighting circuits, either the Schrack Smart Building Automation Light Module "L1244" with integrated 230 V/16 A relays or the Light Module "L1144" for connecting external relays can be used, depending on the application and load. Each module can control four lighting circuits.

Example:
Two normal and two dimmable lighting circuits are planned for the bedroom.

The two normal lighting circuits are used for the ceiling and balcony lighting. A Schrack Smart Building Automation Light Module "L1244" with integrated 16 A relays is used for this purpose. Two of the four outputs are used, leaving the remaining two outputs available for other lighting circuits.

The two dimmable lighting circuits are used for the reading lights on the left and right sides of the bed. A Schrack Smart Building Automation Dimming Module "L1424" is used for these circuits. An appropriate external dimmer is additionally required for each lighting circuit.
