2-Channel 0/4 to 20 mA Analog Output Terminal

Product Description

The KL4012 and KL4022 analog output terminals generate analog output signals within the
range from 0 / 4 to 20 mA. The current is transported to the process level in an
electrically isolated fashion with a resolution of 12 bits. The output channels of one bus
terminal possess a common earth potential with the 24 V DC power supply. The output stages
are powered by the 24 V power supply. The RUN LEDs indicate operational status and the
logical connection to the bus coupler.
