The DALI standard (IEC 60929), a protocol across all manufacturers, ensures the interoperability of electronic ballasts in lighting applications. This standard replaces the 1–10 V dimmer interface.
The DALI/DSI Master for the WAGO I/O System 750 is a 12mm wide I/O module that fits all 750 Series Controllers.
A DALI Master can control up to 64 slaves. Each slave can be assigned to 16 individual groups and 16 individual settings.
Using the WAGO I/O System 750, DALI controllers can be seamlessly integrated into other building systems. Several DALI Masters can be connected to a single fieldbus node. The maximum number of modules that can be connected to a controller depends on the memory required by the application.
Fieldbus nodes are programmed via WAGO-I/O-PRO Software. WAGO supports simple application programming with pre-programmed function blocks for DALI.
The 288-895 DC/DC Converter is required to supply the DALI Master. The DC/DC converter delivers up to 400 mA and can supply three DALI lines each with up to 130 mA (see also "DALI/DSI Master Module" manual* in section 1.1.1.7.3 "DALI Bus Line"). *Documentation available in German and English.
DSI is a proprietary interface which was developed by the TRIDONIC ATCO company. As with DALI, electronic ballasts can be digitally controlled by the DSI. However, compared to DALI, the DSI slaves cannot be addressed individually and no feedback signals can be sent to the master. The maximum number of slaves controlled by the module is limited to 100 participants per line (100 participants* 2 mA = 200 mA). Just as for DALI, the 288-895 DC/DC Converter is required to supply the DSI.
