Product Description:

The KM2002-0000 is a digital output terminal manufactured by Beckhoff within the KM Bus Terminals series. It occupies one slot on a 35 mm DIN rail and converts command bits on the internal K-bus into 24-volt switching signals. Integrating this module into a control cabinet allows a PLC or IPC to actuate field devices without dedicated wiring looms, streamlining distributed machine I/O. The terminal therefore serves as a modular building block for deterministic on-off actuation in industrial automation lines.

Each of the sixteen outputs is referenced to the common 0 V of the system and is rated for a nominal voltage of 24 VDC. A per-channel continuous load of 0.5 A permits direct driving of small solenoids or indicator lamps without external relays. The terminal is organized as two connectors, each carrying 16 (2 × 8) points divided into groups of 8 channels, simplifying ribbon-cable breakout to terminal blocks. Output drivers draw their logic power from the backplane, so the internal electronics are supplied exclusively by the K-Bus, eliminating separate auxiliary voltage feeds. Ohmic, inductive, and lamp loads are supported, giving flexibility across mixed field devices.

Thermal and electrical safeguards are embedded in the design. The output stage incorporates short-circuit and overload monitoring, and the energy that can be dissipated during a switching event is limited to <150 mJ/channel, protecting sensitive wiring. Backplane consumption stays low; the module draws only 5 mA from the K-bus for its logic functions, while load current is sourced externally. Mechanical installation is flexible thanks to its variable mounting attitude and the standard 35 mm rail interface. An enclosure rating of IP20 restricts use to control cabinets where ingress of foreign objects and moisture is controlled.
