Beckhoff Automation kl4021

The KL4021 analog output terminal generates 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 run LEDs give an indication of the data exchange with the Bus Coupler.
