Beckhoff KL4424 Analog Output Terminal

The Beckhoff KL4424 is a 4-channel analog output Bus Terminal designed to deliver precision current signals in the 4–20 mA range. With a 12-bit resolution and electrically isolated signal output, this terminal ensures accurate current control for process automation and industrial control systems. All four outputs are implemented as 2-wire, single-ended channels, making integration simple and effective across various I/O applications.

Ideal for current loop control, the KL4424 features short-circuit protection, fast conversion, and robust EMC compliance. Diagnostic LEDs provide immediate feedback on communication with the Bus Coupler. It supports both 24 V DC and 15 V DC (via KL9515), offering flexibility in supply configurations.
