KL4434, KL4438 | 4-, 8-channel analog output terminals -10…+10 V

The KL4434 and KL4438 analog output terminals generate signals in the range between -10 to +10 V. The voltage is supplied to the process level with a resolution of 12 bits and is electrically isolated. In the KL4434 Bus Terminal, the four outputs are 2-wire versions. The KL4438 combines eight channels in one housing and is 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.
