Product Description:
The KL2408-0000 is an I/O terminal from Beckhoff designed to distribute 24 V DC switching signals to actuators in decentralized control systems. Installed on a 35 mm DIN rail next to a Bus Coupler or Embedded PC, the terminal condenses eight separate channels into a 12 mm wide housing to reduce cabinet space. In industrial automation lines, it provides the programmable interface between the PLC and solenoids, lamps, or contactors that require galvanically separated low-power switching.
Each channel operates from a nominal supply of 24 V DC, and it can source up to 0.5 A to the connected load. The output transistors use positive switching, so voltage is applied on activation while the return is common. Internal circuitry follows the 1-wire connection scheme, which combines signal and supply on a single conductor to simplify field wiring. The module maps one byte in the process image, giving the controller direct access to 8 outputs with a single bus transaction. Variable installation orientation does not affect thermal performance, and the terminal supports ohmic, inductive, and lamp loads. Reverse-polarity protection helps prevent damage if the field supply is wired incorrectly.
For system power distribution, the power contacts integrated into the housing can carry up to 10 A, allowing several terminals to share a common feed without external jumpers. Each de-energized channel can absorb less than < 150 mJ/channel of breaking energy, which helps limit voltage spikes across coils. The enclosure meets IP20, so live parts are finger-safe while ventilation is maintained for cabinet operation. If a downstream fault drives the line beyond rated conditions, an electronic fuse limits short-circuit current to < 2 A, and the controller can diagnose the event through the fieldbus. The narrow housing keeps the terminal compact within the I/O row.
