Beckhoff KL2404 Bus Terminal

The Beckhoff KL2404 is a 4-channel digital output terminal designed for switching 24 V DC control signals to actuators in industrial automation systems. Supporting 2-wire connections and providing four ground terminals, the KL2404 enables the direct connection of actuators with a shared return path, simplifying wiring and improving cabinet layout efficiency.

Each output is short-circuit proof and protected against reverse polarity, with clear LED status indication per channel. The KL2404 is ideal for applications involving ohmic, inductive, or lamp loads.
