Overview
The Allen-Bradley 2090-UXBB-DM15 is a dedicated motor feedback breakout board engineered for industrial motion control applications. Designed as part of the Bulletin 2090 series, this breakout board simplifies the distribution of motor feedback signals in Ultra3000 and KINETIX drive systems by converting a bundled CN2 connector into individual screw terminals. The board eliminates the need for complex inline connectors and enables cleaner, more accessible wiring configurations in automated machinery and process control environments.
Key Features
- 15-pin male D-sub connector—compatible with Ultra3000 CN2 feedback connector for seamless drive integration
- Screw terminal outputs (30–16 AWG)—enables secure, field-serviceable wire connections
- Drive-mounted design—mounts directly to Ultra series drives for compact, integrated feedback distribution
- Robust construction with maximum cable diameter of 11.4 mm (0.45 in.)—suitable for diverse industrial applications
- KINETIX 300, 350, 2000, 6000, 6200, 6500, and 7000 drive family compatibility
- Standardized terminal torque specifications (0.25 Nm terminal screws, 0.40 Nm mounting screws)—ensures consistent, reliable assembly

Typical Applications
The 2090-UXBB-DM15 is commonly deployed in the following industrial automation and motion control scenarios:
- Servo Motor Feedback Distribution: Breaking out encoder or resolver signals from Ultra3000 drives to multiple control inputs
- KINETIX Drive Integration: Connecting motor feedback networks in modular KINETIX drive systems (300, 350, 2000, 6000, 6200, 6500, 7000)
- Machinery Control Wiring: Simplifying motor feedback connections in factory automation, packaging equipment, and material handling systems
- Retrofit and Maintenance: Replacing worn or damaged breakout boards in existing Ultra3000 control cabinets without drive replacement
Compatibility & Replacements
The 2090-UXBB-DM15 is purpose-built for Ultra3000 CN2 feedback connectors and is compatible with KINETIX 300, 350, 2000, 6000, 6200, 6500, and 7000 drive families. It is not interchangeable with other Allen-Bradley breakout boards designed for different connector types or drive series. Rockwell Automation has not announced a planned replacement for this product following its December 2022 discontinuation, making available surplus units critical for ongoing system support and maintenance. When sourcing alternatives, verify CN2 connector compatibility and KINETIX drive series to ensure correct integration.
