Overview
The Beckhoff KL3051 is a 1-channel analog input Bus Terminal for 4–20 mA current loops. It supplies power to field transducers via the power contacts and transfers the measured value to the controller with electrical isolation from the K‑bus. Run LEDs indicate data exchange; error LEDs signal wire break or overload. The input electronics are independent of the power‑contact supply.
Key Features
- 1 analog input, 4–20 mA (single-ended)
- Integrated sensor supply via power contacts
- 12-bit resolution; ~1 ms conversion time
- 500 V isolation between K‑bus and signal voltage
- Overload and wire-break indication
- Compact 12 mm width for high-density installations
