Beckhoff Automation KL2408 Digital Output Module

Beckhoff KL2408 is an 8-channel digital output terminal for 24 V DC loads, designed to connect binary control signals from the automation unit to field actuators with galvanic isolation between the controller and the process. Each of its eight outputs can source up to 0.5 A at 24 V DC, with per-channel LEDs to indicate state, and built-in protections against overload, short-circuit, and reverse polarity to help prevent damage to connected devices. The KL2408 uses 1-wire connection technology (K-Bus) for a compact, space-saving installation in control cabinets, and its 24 V power contact is looped through to feed subsequent modules in the same chain. As part of Beckhoff's KL2xxx digital output family, the module is designed for single-ended signaling and is suitable for driving relays, contactors, solenoids, LED indicators, and other 24 V DC actuators in applications such as packaging lines, machine automation, and process control. With eight discrete channels in a compact bus-terminal form factor, the KL2408 enables scalable, modular I/O for industrial automation, offering straightforward diagnostics through per-channel indicators and a robust, space-efficient solution for modern control panels.
