Photocell

These two-part photocells are designed to monitor the amount of ambient daylight and are used for controlling the light facilities of streets, external stairways, shop windows, entrances etc.
The Luna 121 includes a Time Clock for scheduling switching times.

The Photocells are supplied in two parts:
The light sensor can be mounted up to 100 metres from the control unit. The sensor is designed for outdoor installation.
The control unit can be used to select the range of illuminance and has an LED to indicate when it is switched
on. The control unit is for use only in closed, dry rooms.
