KL4021, KS4021, KL4022, KS4022 | 1-, 2-channel analog output terminals 4…20 mA

The KL4021 and KL4022 analog output terminals generate analog output signals in the range from 4 to 20 mA. The power is supplied to the process level with a resolution of 12 bits and is electrically isolated. Ground potential for the output channels of a Bus Terminal is common with the 24 V DC supply. The output stages are powered by the 24 V supply. The KL4021 is the single-channel variant. The KL4022 combines two channels in one housing. The run LEDs give an indication of the data exchange with the Bus Coupler.
