Wago 750-641 fieldbus module

DALI/DSI master module The DALI standard (IEC 60929), a protocol across all manufacturers, ensures the interoperability of electronic ballasts in lighting applications. This new standard is substitute for the 1–10V dimmer interface. The DALI/DSI Master for the WAGO‐I/O SYSTEM 750 is a 12mm wide I/O module that fits all controllers of the 750 series. A DALI Master can control up to 64 slaves. Each slave can be assigned to 16 individual groups and 16 individual settings. Any combinations of DALI controls with other groups are possible with the WAGO‐I/O-SYSTEM 750. Several DALI Masters can be connected to a single fieldbus node. The maximum number of modules within a controller depends on the memory requirements of the application. The WAGO-I/O-PRO 32 software is used to program the fieldbus nodes. WAGO supports simple application programming with pre-programmed function blocks for DALI. The DC/DC converter 288-895 is required to supply the DALI Master. The DC/DC converter delivers up to 400mA and can supply 3 DALI lines each with up to 130mA (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 slaves of the DSI module 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 perticipants per line (100 participants * 2 mA = 200 mA). Just as for DALI, the DC/DC converter 288-895 is required to supply the DSI.
