The KL4022 is a two-channel analog output terminal from the Beckhoff Bus Terminal series (KL series) for the traditional K-Bus I/O system. It outputs 0–20 mA or 4–20 mA current-loop signals with 16-bit resolution, providing finer output steps than the 12-bit KL4012. It is used to control multiple actuators, valves, and drives that accept an analog current setpoint where higher output resolution is required. It belongs to the same high-resolution current-loop output family as the KL4021. 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.

The KL4021 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 0–20 mA or 4–20 mA current-loop signal with 16-bit resolution, providing finer output steps than the 12-bit KL4011. It is used to control actuators, valves, drives, and other devices that accept an analog current setpoint where higher output resolution is required. It belongs to the KL4xxx high-resolution analog output 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.

The KL3681 is a single-channel digital multimeter terminal from the Beckhoff Bus Terminal series (KL series) for the traditional K-Bus I/O system. It integrates a digital multimeter (DMM) function into a standard Bus Terminal, enabling automated measurement of voltage, current, resistance, and other electrical quantities directly within the K-Bus I/O system. It is the K-Bus counterpart to the EtherCAT EL3681. 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.

The KL3468 is a three-phase power measurement terminal from the Beckhoff Bus Terminal series (KL series) for the traditional K-Bus I/O system, designed for direct measurement of electrical power in three-phase AC systems. Based on its designation, it combines the KL34xx power measurement feature set with 8 current input channels (for multi-circuit or multi-path current measurement). The exact channel configuration and functional scope must be confirmed against the current Beckhoff datasheet.

The KL3464 is a three-phase power measurement terminal from the Beckhoff Bus Terminal series (KL series) for the traditional K-Bus I/O system, designed for direct measurement of electrical power in three-phase AC systems. It measures voltage and current on all three phases and calculates RMS values, active/reactive/apparent power, power factor, frequency, and energy, delivering the results to the controller. It belongs to the KL34xx power measurement family; the exact feature differences versus the KL3403, KL3404, KL3444, KL3454, and other variants should be confirmed in the current Beckhoff datasheet.
