The Beckhoff KL3404 Bus Terminal is engineered for reliable acquisition of analog voltage signals in industrial automation applications. It supports four single-ended inputs with a signal range of −10 V to +10 V, digitized to 12‑bit resolution (11-bit for the 0–10 V range), ensuring precise and accurate measurements. The module is powered via the K-bus and provides electrical isolation of 500 V between the bus and signal circuits, protecting both the module and connected devices.
Designed for robust operation, the KL3404 can function within a temperature range of −25 °C to +60 °C and be safely stored between −40 °C and +85 °C. The module withstands relative humidity up to 95% (non-condensing) and meets industrial standards for vibration and shock according to EN 60068-2-6 and EN 60068-2-27. EMC immunity and emission compliance are ensured according to EN 61000-6-2 and EN 61000-6-4.
The module features a plug-in wiring interface compatible with all KSxxxx Bus Terminals, simplifying installation and integration. LEDs indicate active data exchange with the Bus Coupler, providing immediate visual confirmation of operational status. No address or configuration setting is required, making the KL3404 highly user-friendly for a variety of Beckhoff control applications.
Optimized for high-performance industrial automation, the KL3404 Bus Terminal combines precision measurement, electrical safety, and straightforward integration, making it an essential component for analog signal processing in Beckhoff systems.
