Overview
The Allen-Bradley 2098-DSD-005X is a digital indexing servo drive from the Ultra3000i series, manufactured by Rockwell Automation. This drive delivers stand-alone control capability for repeatable, precision motion control applications requiring step-and-move operation. The 2098-DSD-005X is widely deployed in manufacturing environments for rotary indexing tables, carousel positioners, and packaging machinery where standardized motion profiles must repeat reliably with minimal operator intervention.
Key Features
- Single-phase input supply: 100–240V AC rms at 47–63 Hz (no three-phase required)
- Output current: 2.5A continuous (0-peak), 7.5A intermittent (0-peak)
- Output power: 0.25 kW at 115V AC, 0.5 kW at 230V AC input
- Eight optically-isolated 12–24V active high-current sinking digital inputs; four optically-isolated 12–24V current-sourcing digital outputs
