Beckhoff KL3052 Analog Input Terminal

The Beckhoff KL3052 is a 2-channel analog input terminal for measuring current signals in the 4–20 mA range. This module is designed for single-ended current measurements with integrated electrical isolation and built-in sensor supply via the power contacts. Ideal for industrial automation systems, it supports precise analog signal acquisition from field devices like pressure, flow, or temperature transmitters.

The KL3052 features 12-bit resolution, integrated diagnostics with RUN/ERR LEDs, and seamless K-bus integration, enabling accurate and reliable analog data transfer to the PLC or controller.
