DALI-2 RS232 PS240mA, LUBA Protocol

The Lunatone DALI-2 RS232 PS240mA LUBA combines two functions that normally occupy two positions on the rail: a bidirectional RS232-to-DALI interface using Lunatone's documented LUBA protocol, and an integrated 240mA DALI bus power supply strong enough for a fully loaded 64-device line. Connect a PLC or automation controller on one side, and the module runs and powers the entire DALI line on the other.

Key features

• Bidirectional RS232 communication with the DALI bus: control commands, addressing, configuration, status queries and monitoring
• LUBA protocol (Lunatone Universal Building and Automation Protocol) — documented, structured access supported by DALI Cockpit 1.38.60+
• Integrated 240mA DALI bus power supply — no separate DALI PS needed
• Serial parameters: 38400 baud, 8 data bits, no parity, 1 stop bit
• Successor to the DALI RS232 PS240mA (24166096-PS)
