Why Choose the WAGO 750-641 DALI/DSI Master Module?
The WAGO 750-641 is a specialised DALI/DSI master communication module designed for the WAGO I/O System 750. It enables PLC and controller systems to integrate digital lighting control networks directly into industrial automation or building management systems.
Using the internationally recognised DALI lighting control protocol (IEC 60929), the module allows electronic ballasts and lighting devices to be digitally controlled and monitored. It can manage up to 64 DALI devices on a single bus, allowing engineers to implement flexible lighting automation, grouping and scene control across industrial or commercial environments. :contentReference
The module also supports the DSI lighting interface, a digital lighting protocol widely used with electronic control gear. Installed on a DIN rail within the WAGO modular I/O system, the module provides a simple and reliable way to integrate intelligent lighting networks into distributed automation systems. :contentReference
