DALI External Photocell

The external photocell connects to Prolojik LCMs and hubs to provide a sample of external daylight levels for use with daylight linking.

An Integral feedback LED allows for the installer to easily verify correct wiring and identify connection.

Prolojik’s PS320 External Photocell is designed to work with Prolojik PL and PC series lighting controllers. The photocell delivers high accuracy light level measurement.
