### Key Technical Benefits

* Enhanced Safety Logic: The 3.1 revision features improved safety-rated I/O and dual-channel safety circuitry, allowing for Category 3, PLd safety configurations without complex external hardware.
* Proven Stability: As the final and most refined iteration of the CB3 series, the 3.1 controller is optimized for high uptime and is compatible with a massive library of legacy UR+ grippers and sensors.
* Programming Versatility: Supports both Graphical Programming (Polyscope) for beginners and URScript for advanced users who require complex logic and external peripheral control.
* Small Footprint: The compact cabinet design allows it to be tucked under workstations or mounted in tight spaces, mirroring the agility of the UR5 arm itself.

### Connectivity & Expansion
The CB3.1 controller acts as the central hub for your entire work cell:
* Tool I/O: Provides 12V/24V power and I/O directly at the tool flange, minimizing the need for external cables along the arm.
* Remote Control: Can be easily integrated into a Master PLC system via standard industrial Ethernet protocols.
* Quick Setup: Features a "Teach" button on the back of the pendant for easy manual guidance of the robot arm.
