Beckhoff Automation GmbH & Co. KG KL4004 PLC Module

Beckhoff KL4004 is a four‑channel analog output bus terminal designed for Beckhoff’s KL I/O system, delivering four independent 0–10 V voltage outputs with 12‑bit resolution. This plug‑in module belongs to the KL400x family of analog output terminals and is also available as KS4004 with pluggable wiring level, enabling compact, distributed I/O configurations within a Beckhoff automation setup. Each channel provides precise voltage outputs suitable for driving external devices such as actuators and other analog loads, with LED indicators per channel to monitor output status. The KL4004 is intended for integration into Beckhoff automation architectures where multiple simultaneous analog setpoints are required, providing a straightforward path to implement multi‑channel analog control in industrial applications.
