Overview
The Allen-Bradley 193132 Rev 05 is a control board and cassette assembly designed for the PowerFlex 700 series adjustable frequency AC drive. This component houses the vector control electronics and I/O terminal blocks that enable precise motor control in industrial variable frequency drive (VFD) systems. The 193132 is a critical replacement part for engineers and maintenance technicians maintaining PowerFlex 700 installations across manufacturing, HVAC, pump/fan, and material handling applications.
Key Features
- Vector control capability with Allen-Bradley Force Technology for advanced motor control
- Integrated I/O cassette with modular mounting points for optional feedback and communication cards
- Compatible with PowerFlex 700 Frames 0–10 drive systems
- Support for encoder feedback: 12V DC and 5V DC jumper-selectable input options
- Sensorless vector and volts/hertz (V/Hz) control modes supported
- DPI communication ports for industrial network integration (ControlNet, DeviceNet, EtherNet/IP capable)

Typical Applications
The 193132 control board is deployed in industrial automation systems requiring variable-speed AC motor control, including:
- Centrifugal pump and fan speed control with variable-torque efficiency
- Conveyor and material handling speed regulation
- HVAC blower and chiller motor drives
- Oil well, lifting, and positioning applications demanding sensorless or vector control
- Multi-motor systems with DPI-based master/slave or coordinated control
Compatibility & Replacements
The 193132 is a cassette/control board module specifically designed for Allen-Bradley PowerFlex 700 drives. Compatible frame sizes include Frames 0, 1, 2, 3A, 3B, 4, 5, 6, 7, 8, 9, and 10. This modular cassette can be removed and replaced without disturbing main conduit or power wiring—a key advantage for field service. The board integrates I/O terminal blocks and houses all vector control, encoder feedback, and communication logic. Standard replacement procedures require disconnecting two cable connectors and releasing two screw latches. When upgrading or troubleshooting vector control function loss, confirm your drive frame size and original control board revision before ordering. Related components include HIM (Human Interface Module) LCD displays, communication adapter cards, and optional I/O terminal block kits that mount to this cassette.
