Overview
The Allen-Bradley 160-BA03NSF1 is a variable speed drive and analog signal follower controller designed for precise, closed-loop control of AC induction motors in industrial automation systems. Part of the 160 SSC Series, this compact drive accepts analog input signals (±10 VDC or 4–20 mA) and potentiometer inputs to regulate motor speed from 0 to 240 Hz. Though discontinued by the manufacturer, it remains a reliable choice for legacy system replacement and retrofit applications.
Key Features
- Analog signal follower mode with ±10 VDC or 4–20 mA input compatibility
- Compact, open (IP20) enclosure design with low panel space footprint
- Programmable output frequency range: 0 to 240 Hz
- Integral I/O terminals (TB3) for Start/Stop and reverse rotation control
- Optional Program Keypad Module or remote handheld device for local configuration
- Front-panel Ready/Fault LED status indicators for drive feedback
- Over-voltage, under-voltage, and over-temperature protection
