KL4424

4-channel analog output terminal 4?20 mA, 12 bit

4 x 2-wire system

Categories: ,

Description

The KL4424 analog output terminal generates signals in the range between 4 to 20 mA. The power is supplied to the process level with a resolution of 12 bits and is electrically isolated. The output stage is powered by the 24 V supply. In the KL4424, the four outputs are 2-wire versions.

The Bus Terminal has a common ground potential. The power contacts are connected through. The reference ground of the outputs is the 0 V power contact. The LEDs indicate the data exchange with the Bus Coupler.
