Beckhoff KL3052 is a two-channel analog input terminal for 4–20 mA current loops, part of the KL3xxx/KL304x family. Each channel provides 12‑bit resolution on a single-ended input and supports measuring ranges of 0–20 mA and 4–20 mA. The module is powered by 24 V DC via its power contacts, supplying the sensor loop and the terminal’s own electronics. It includes Run1 and Run2 LEDs to indicate normal operation, helping verify channel status at a glance.
