Allen-Bradley 291D-FBZ-G2-3FR ArmorStart LT Reversing Starter

Technical Specifications Breakdown

Key parameters for the 291D-FBZ-G2-3FR are listed below for quick reference:

Real-World Applications That Benefit

Conveyor Systems:The DeviceNet communication allows seamless integration with PLCs for coordinated control and diagnostics.

Packaging Machinery: In packaging lines, space is often limited. The on-machine design of this controller saves valuable panel space and reduces wiring complexity. The Hand/Off/Auto (HOA) selector keypad with Forward/Reverse (factory option -3FR) gives operators local control for setup and maintenance, while still allowing remote automatic operation.

Material Handling Equipment: For hoists, lifts, and other material handling equipment, the reversing starter provides reliable direction control. The local logic technology using DeviceLogix enables standalone operation even if network communication is lost, ensuring safety and productivity.

Installation and Setup Guidance

When installing the 291D-FBZ-G2-3FR, follow the manufacturer's wiring diagrams and local electrical codes. The unit requires an external 24V DC control power supply (19.2…26.4V DC). Ensure the supply is NEC Class 2 rated and properly protected. The overload relay is factory set for the motor's full load current (FLC) within the 1.1…7.6 A range. Adjust the overload setting to match the motor nameplate. Use the quick-disconnect connections for I/O and power to speed up installation. For DeviceNet, terminate the network properly and set the node address and baud rate via the rotary switches (if present). Always verify that the motor is disconnected before performing any wiring changes.

Maintenance and Reliability Tips

Periodic inspection of the enclosure seals and cable glands is recommended to maintain the IP66 rating. Check for loose connections and signs of overheating, such as discoloration or burning smell. The unit is designed for long service life, but environmental factors like high humidity (5…95% non-condensing) and temperature extremes (-20…+50 °C operating) can affect performance. Keep the enclosure clean and ensure adequate ventilation around the unit. The overload relay provides automatic or manual reset; select the appropriate mode for your application. Test the E-stop and safety circuits regularly.

On-Machine Motor Control That Keeps Production Moving

The Allen-Bradley 291D-FBZ-G2-3FR ArmorStart LT distributed motor controller is designed to prevent that scenario. This reversing starter brings full-voltage starting and reversing capability directly to the machine, eliminating long control wiring runs and simplifying installation. Built for harsh environments, it delivers reliable performance in applications where conventional panel-mounted starters are impractical.

Engineered for On-Machine Durability

The 291D-FBZ-G2-3FR is housed in a robust IP66/UL Type 4/12 enclosure, making it suitable for washdown and dusty environments. This protection level ensures the internal electronics remain safe from water ingress and particulate contamination, which is critical for food processing, packaging, and material handling lines. The unit supports quick-disconnect connections for I/O communications, reducing installation time and simplifying maintenance. Conduit entrance or ArmorConnect power media gland plate options provide flexibility in how power and motor cables are routed.

Compatibility and Integration

The 291D-FBZ-G2-3FR uses DeviceNet for communication, which is a widely adopted industrial network. It can be integrated with Allen-Bradley PLCs and other DeviceNet scanners. The DeviceLogix local logic allows the controller to execute simple logic functions without continuous network communication, improving response time and reliability. The unit also supports peer-to-peer (ZIP) communication for DeviceNet versions, enabling interlocking between multiple starters without a master controller.
