The KL4404, KL4408, KL4434 and KL4438 analog output terminals generate signals in the range between 0 to 10 V or -10 to +10 V. The voltage is supplied to the process level with a resolution of 12 bits and is electrically isolated. In the KL4404 and KL4434 Bus Terminals, the four outputs are 2-wire versions. The KL4408 and KL4438 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.
