OPTOTRONIC® Programmable LED Driver with DEXAL® Technology

The OSRAM OPTOTRONIC LED Programmable Driver with DEXAL Technology, is a non-proprietary, intra-luminaire interface, based on DALI-2 communications, that enables bidirectional communications between the driver and the fixture-integrated component. It provides exact luminaire-specific data, including diagnostics, to light management systems. 

Fixture manufacturers can design smart fixtures and streamline the configuration process by leveraging DEXAL as a standard bi-directional communications interface.

Uses the CBU-DCS to communicate the the network.
