Mischlicht-Sensor für Deckenein-/ aufbaumontage. Dient zur Mischlichtaufnahme in geschlossenen Räumen und kann zur Lichtkonstanthaltung verwendet werden. Der Messbereich beträgt 0 – 700 Lux in einer Messkeule von 60 Grad. Die Ausgabe des Messwerts erfolgt über 0 – 10 VDC. Die Verbindung mit der Zentraleinheit erfolgt über GLS-SIM oder DIN-IO8. Eingangsmodule. Maße : H= 2,52 cm, D= 6,41 cm.

The GLS-LCL is a photocell sensor designed for daylight harvesting applications to control the balance of natural and artificial lighting in an indoor space. By harnessing natural daylight from windows and skylights, electrical lighting can be dimmed, reducing energy usage while maintaining a consistent light level for a more efficient and comfortable work or living space.

Intended for use with closed-loop type daylight harvesting systems, the GLS-LCL continually monitors the total ambient light level from all available light sources, enabling precise control of room lighting and window shades to maintain a consistent level of light throughout the day. The best place to install the GLS-LCL in a typical office or similar space is on the ceiling directly above the primary work area. The sensor measures all light within a 60° cone, which consists predominately of reflected light, acquiring the most natural approximation of perceived changes in ambient light levels.

The GLS-LCL includes hardware to facilitate flush or surface mounting to a drywall or drop-tile surface. It can also be mounted to a standard 4-inch octagon box. Its simple 3-wire interface allows for direct connection to a Crestron control system via a single Versiport I/O or analog input port, with 24 Volt power taken from the Cresnet® control bus[1].

Using the optional GLS-SIM Sensor Integration Module, the GLS-LCL becomes a full-featured Cresnet device, streamlining the total lighting system. Cresnet provides a simpler solution for configuring and wiring sensors as part of any complete Crestron system. Cresnet is the communications backbone for Crestron lighting dimmers, keypads, touchpanels, shade controllers, thermostats, and many other devices. This flexible 4-wire bus provides data communications and 24 Volts DC power for all of the devices on the Cresnet network.
