Beckhoff KL4424 Four Channel Digital Input Module

Beckhoff KL4424 is a four‑channel analog output terminal for the Beckhoff Bus Terminal system. Each channel provides a 4–20 mA current‑loop output with 12‑bit resolution, enabling precise control of analog actuators and instrumentation. The four outputs are implemented in a 2‑wire configuration per channel, simplifying wiring for common current‑loop loads. As a member of the KL4xxx family, the KL4424 integrates with Beckhoff’s K‑bus/I/O architecture and is designed for use in EtherCAT‑enabled automation environments via compatible bus couplers. Typical applications include driving proportional valves, current‑loop actuators, and other devices that accept a 4–20 mA signal, with digital values from the controller mapped into the 4–20 mA range for accurate process control. This module provides reliable, multi‑channel analog output within industrial automation or process control systems that require precise, independent current outputs.
