KL4001 Beckhoff CX system

The KL4001 is a single-channel analog output terminal from the Beckhoff Bus Terminal series (KL series) for the traditional K-Bus I/O system. It outputs a 0–10 V voltage signal to control actuators, valves, drives, and other devices that accept an analog voltage setpoint. It belongs to the KL4xxx analog output family, which typically offers higher resolution than the KL3xxx family. Unlike EtherCAT terminals (EL series), the KL series communicates via the K-Bus and is typically used with Beckhoff Bus Couplers or Bus Terminal Controllers.
