The EL6821 allows up to 64 DALI-/DALI-2 slaves and 64 DALI-2 input devices to be connected. The TwinCAT 3 System Manager makes it easy to configure and parameterize DALI devices. Programming is performed exclusively via TwinCAT 3 function blocks. The EL6821 contains an integrated DALI bus power supply that can be switched off. The galvanically isolated input voltage of 24 V DC must be supplied via the EL9562 power supply terminal or via the PS1111-2402-0002, PS1111-2403-0000, or PS1111-2403-0002 power supplies in order to comply with the certification requirements.

 

The EL6821 is certified in accordance with the DALI-2 standard.
