Allen-Bradley 2090-XB120-06 Resistive Brake Module – 107A Peak, 6 Ohm, for Kinetix Servo Drives

The 2090-XB120-06 is a high-capacity resistive brake module from Rockwell Automation's Bulletin 2090 series, engineered to handle regenerative energy in Kinetix servo systems. Mounts externally to absorb braking energy, protecting drives from bus overvoltage in demanding motion applications.

Key Features

• 6 Ohm resistance for efficient energy dissipation
• 107 A peak current handling (suitable for larger Kinetix axes)
• Compatible with 230V and 460V Kinetix drives (e.g., 6000 series)
• Supports high duty cycles and 15:1 inertia mismatch
• Panel-mount design with thermal monitoring (fault/warning outputs)
• Open type enclosure, forced air cooling recommended
• I/O for temperature fault/warning signaling
• Certifications: cULus, CE, etc.
