Overview
The Allen-Bradley 2090-U3BB2-DM44 is a control interface breakout board kit engineered for Ultra 3000 and Kinetix 2000 servo drives. This drive-mounted 44-pin assembly terminates discrete control signals on the CN1 connector, eliminating the need for complex point-to-point wiring. The board ships as a complete kit with integrated cable harness, DIN rail terminal block, and mounting hardware—reducing integration time on new machine builds and retrofit installations.
Key Features
- 44-pin D-shell connector for broad signal termination capacity
- Complete assembly kit with pre-routed cable and DIN rail terminal block included
- Drive-mounted design for compact, integrated control signal routing
- Wire termination supports 30–16 AWG (0.06–1.31 mm²) conductors
- External 5.2V DC auxiliary power keeps control logic live when drive power is lost
- Cable shield termination pad with shrink-wrapped insulation for noise immunity
Technical Specifications
The breakout board features a 44-pin male D-sub connector with labeled signal terminals (1–44) plus dedicated +X and –X power connections. Wire termination maximum diameter is 0.5 inches (12.7 mm), with screw terminal torque rated at 0.25 N⋅m (2.2 in⋅lbs). Recommended wire strip length is 1–2.5 inches (25–63 mm). Physical dimensions are 2.6 × 2.0 × 0.9 inches (65.4 × 50.9 × 21.8 mm). Storage temperature range is −55 to +85°C. The kit includes interconnecting cable and standard mounting hardware for field installation on Ultra 3000 drives.
Typical Applications
- Discrete I/O termination for Ultra 3000 servo drive control networks
- Machine automation and motion control systems requiring hardwired logic integration
- Retrofit projects converting point-to-point wiring to structured interface boards
- Industrial robotic systems, packaging equipment, and CNC machine tool drives
