Tired of robot controllers that take up too much space and need a tech team to keep them running? The KUKA KR C4 Compact Robot Controller is a small, powerful brain for your automation line. It lets you run KUKA robots with fast programming and reliable motion control. If you have limited floor space or need a controller that can be installed quickly, this unit solves the problem.
KUKA KR C4 Compact Robot Controller
Many factories struggle with bulky controllers that block aisles and require long wiring runs. That problem slows production and raises maintenance costs. The KR C4 Compact solves it by delivering full KUKA functionality in a footprint that fits under a workbench. Its integrated power supply, Ethernet ports, and smartPAD mean you can hook it up and start teaching robots in minutes, not days. The result is less downtime, lower installation expense, and a smoother workflow.
Benefits
- Small footprint fits tight work cells, freeing up valuable floor space.
- Built-in smartPAD makes programming intuitive, so operators can teach the robot without expert help.
- IP54 protection keeps the controller safe from dust and splashes in harsh factory environments.
- Dual Ethernet ports give fast communication with PLCs, vision systems, or cloud services.
- 2 GB memory stores complex motion files, allowing smooth operation of multiple tasks.
Key Features
- Dimensions 271 483 460 mm and weight 13.7 kg for easy mounting.
- Rated supply voltage AC 200-230 V with 10 % tolerance for stable power.
- Max power input 2 kVA and thermal dissipation up to 400 W.
- 20-27.1 V DC internal supply and 27.1 V control voltage.
- 2 Ethernet ports and a USB interface for flexible connectivity.
- Optional fieldbus module for integration with legacy automation networks.
- SmartPAD cable length up to 50 m for remote operation.
- Grounding resistance under 100 for safety compliance.
