Описание

The KL6821 enables the connection of up to 64 DALI/DALI 2 slaves and 64 DALI input devices. The KS2000 software enables simple configuration via a PC that is directly coupled with the Bus Coupler via an RS232 interface or via the fieldbus. The integrated power supply unit generates an electrically isolated 24 V DC output voltage. No further components are required for the operation of the DALI/DALI 2 devices. The KL6821 operates fieldbus-independent.
