7LQ2 Dimmer Switches Siemens

Обзор

Dusk switches are used for the demand-oriented switching of lighting installations for shop windows or paths in order to cut operating costs.

A light sensor measures the level of daylight. Switching depends on the desired brightness. A time delay and the switching hysteresis prevent clock-pulse behavior.

The sensor must be mounted so that it is not influenced by the lighting feedback.

Особенности

• The devices 7LQ2 101 and 7LQ2 103 have 2 switching channels that can be set independently of each other. This requires a light sensor
• 12 dusk switches can be switched parallel to a light sensor. This saves the multiple installation of light sensors in a single system and all dusk switches operate independently of each other and can be adjusted individually.
