KL4414, KL4418, KL4424, KL4428 | 4-, 8-channel analog output terminals 0/4…20 mA

The KL4414, KL4418, KL4424 and KL4428 analog output terminals generate signals in the range between 0/4 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 KL4414 and KL4424 Bus Terminals, the four outputs are 2-wire versions. The KL4418 and KL4428 variants combine eight channels in one housing and are particularly suitable for space-saving installation in control cabinets. The use of single conductor connection technology enables the connection of multi-channel actuator technology with minimum space requirements.

The Bus Terminals have 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.
