Product Description:

The KL6821> is a state-of-the-art Bus terminal equipped with a 1-channel communication interface by <. This product makes it possible for operators to connect up to 64 DALI/DALI-2 slaves to 64 DALI-2 input devices. The operation of this terminal can be adjusted to meet specific industrial requirements through a configuration process that can be done through the use of the KS2000 software that is installed on a PC unit. Connection of the configuration PC is made with the aid of a bus coupler through a RS323 interface or the Fieldbus interface present on the unit. The output unit present on this bus terminal is galvanically isolated; the terminal also features a switchable bus power supply unit.

The single data transfer channel on the KL6821 is able to handle transfer rates as high as 1200 bauds, the estimated current consumption of this K-bus is also about 55 milliamperes. During operation, this product uses a nominal voltage supply of 24 volts with a deviation of up to 20 per cent allowed. The insulation voltage of the DALI-Bus/K-bus is estimated to be about 1500 volts of direct current while the maximum DALI power supply is 250 milliamperes>, although this can be turned off.

The KL6821 is equipped with some protective features to make its operation more durable. Its housing is made from strong polycarbonate material with high mechanical strength. The input interface of this product is also able to handle surge voltages as high as 275 volts. Other special features of this product include its 2 digital inputs for simplified installation. The KL6821 is CE certified; it is also estimated to weigh a total of about 80 grams. The protection class of this unit is according to IP20.
