The LDALI‑BM2 pushbutton coupler integrates up to four customary light push buttons and switches into a DALI channel. Alternatively, two of the four inputs can be used as analog inputs to connect devices like sliders, dials or even resistance based sensors like NTC temperature sensors.

Connected pushbuttons or switches can be used to control luminaires and sunblinds using L-DALI lighting controllers or L-ROC room automation controllers.

• Easy integration into LOYTEC L‑DALI lighting systems and LROC‑40x room automation controllers.
• DALI-2 certified input device as defined in IEC 62386 2014 standard.
• 2 digital inputs (dry contact) for conventional pushbuttons or switches.
• 2 universal inputs (potential free) for conventional push-buttons, switches, sliders, dials or NTC temperature sensors.
• Multi‑master compatible, up to 64 LDALI‑BM2 pushbutton couplers per DALI channel with sufficient dimensioned bus supply.
• Supplied via the DALI channel, no external power supply is necessary.
• Pre-confectioned wires for connection of inputs.
• Optimized for mounting behind standard switches.

In the mode toggle, the function is carried out depending on the lighting status (toggle switch). Communication and power supply is handled via the DALI bus. The LDALI-BM2 is a DALI-2 certified input device as defined in the IEC 62386 2014 standard and can be integrated into DALI-2 systems of other vendors.
