KL4438 | Bus Terminal, 8-channel analog output, voltage, ±10 V, 12 bit, single-ended

The KL4438 analog output terminal generates 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. 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 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.
