KL4021 | Bus Terminal, 1-channel analog output, current, 4…20 mA, 12 bit, single-ended

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.
