KL6821 | Bus Terminal, 1-channel communication interface, DALI/DALI-2, master/power supply
KL6821 | Bus Terminal, 1-channel communication interface, DALI/DALI-2, master/power supply
The KL6821 enables the connection of up to 64 DALI/DALI-2 slaves and 64 DALI-2 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. Operation is done exclusively via TwinCAT function blocks. The KL6821 contains an integrated, switchable DALI bus power supply with galvanically isolated output voltage. No further components are required for the operation of the DALI/DALI-2 devices.
The KL6821 is certified according to DALI-2 standard.
