Beckhoff Automation GmbH & Co. KG KL2134 PLC Module

Beckhoff KL2134 is a 4-channel digital output bus terminal in the KL2xxx family that interfaces 24 V DC actuators with the Beckhoff K-bus control system. Each of the four outputs is rated for up to 0.5 A, making it suitable for driving relays, solenoids, contactors, or indicator loads from a single compact module. The unit provides electrical isolation between the automation side and the process load, helping protect the controller and field devices in industrial environments. It requires no separate addressing or configuration—simply snap it onto a 35 mm DIN rail, connect to the K-bus, and wire the 24 V loads to the outputs. This makes the KL2134 ideal for expanding binary output capability in compact automation setups, enabling reliable, plug‑in control of multiple 24 V DC devices from a single Beckhoff controller.
