The Beckhoff KL3011 is a 1-channel analog input bus terminal engineered for precise current-loop acquisition in control panels. Handling 0–20 mA signals with a differential front end and 12-bit conversion, it integrates seamlessly into the Beckhoff Bus Terminal system to expand PLC I/O for machine building, process control, and building automation. Its compact 12 mm housing with status LEDs saves space while delivering dependable channel diagnostics.

Designed for reliable field integration, the KL3011 offers a typical conversion time of ~1 ms and a full-scale accuracy of < ±0.3% FS, with an input burden of 80 Ω (+0.7 V diode). Differential measuring rejects common-mode voltage up to 35 V, while 500 V isolation separates signal from the K-bus. The terminal maps one 16-bit input word to the process image (optional 8-bit control/status) and operates from 0–55 °C in IP20 environments, compliant with EN 61000-6-2/‑6-4 and approved for CE, UL, ATEX and IECEx use.

Supplied for 35 mm DIN-rail mounting with spring-clamp wiring, the KL3011 enables fast commissioning and long-term serviceability in distributed I/O architectures, and it is backed by a 1-year warranty to support uptime across your project lifecycle.
