284D-FVD4P0D-10-CRW-3-DB Allen Bradley

Description

Product Name:  284D-FVD4P0D-10-CRW-3-DB Allen Bradley Power module

Product details:

The 284D-FVD4P0D-10-CRW-3-DB is an Allen-Bradley ArmorStart Distributed Motor Controller with an integrated Variable Frequency Drive (VFD) function. It is part of the Bulletin 284 product family, designed for on-machine, decentralized motor control in demanding industrial environments.

The product catalog number can be broken down to understand its features:

• 284D: Bulletin 284, ArmorStart Distributed Motor Controller (VFD).

• F: Variable Frequency Drive (VFD).

• V: Voltage class (380-480V AC).

• D4P0: Current Rating (4.0 Amperes).

• D: Control Voltage (120V AC).

• 10: Short Circuit Protection rating (10 A rated device).

• CRW: Power/Control/Motor Connection Type (Conduit Entrance, No Motor Cable).

• 3: Option 1 (Hand/Off/Auto Selector Keypad with Jog Function).

• DB: Option 2 (DB Brake Connector for Dynamic Braking).

⚙️ Product Parameters (Specifications)

✨ Product Advantages

• Decentralized Control (On-Machine): The IP67/NEMA Type 4 enclosure allows the VFD to be mounted directly on or near the machine, significantly reducing control panel space and complex wiring runs back to the main cabinet.

• Robust Environmental Protection: The IP67 rating ensures the unit is protected against dust ingress and the effects of temporary immersion or powerful water jets, making it ideal for harsh or washdown environments.

• Integrated VFD Functionality: Provides variable speed control, enabling energy savings, precise process control, and smooth motor starting/stopping (soft start/stop) for reduced mechanical stress.

• Simplified Communication (DeviceNet): Integrates seamlessly into a DeviceNet network, allowing for easy configuration, diagnostics, and control from a central PLC.

• Integrated Dynamic Braking (DB Connector): The included DB connector allows for the simple connection of an external braking resistor, providing fast and controlled deceleration of high inertia loads.

• Local Control: The optional Hand/Off/Auto Selector Keypad with Jog Function provides local control and diagnostics directly at the machine, simplifying setup and troubleshooting.

⚠️ Important Considerations (Notes)

1. Installation and Wiring: Due to the high IP rating, ensure that all conduit entrances, connections, and cable glands are sealed correctly to maintain the IP67/NEMA Type 4 integrity.

2. Dynamic Braking Resistor: The unit includes a DB connector but does not include the dynamic braking resistor itself. An appropriately sized external resistor must be selected and installed for the braking function to operate.

3. Motor Cable: The “CRW” designation means No Motor Cable is supplied. You must select and install a suitable motor cable, often shielded for VFD applications, to maintain EMI/EMC compliance and optimal performance.

4. DeviceNet Configuration: Proper DeviceNet configuration, including node address, baud rate, and network termination, is essential for successful communication.

5. Heat Dissipation: Although the enclosure is rated for harsh environments, ensure the unit is installed within its specified operating temperature range and has adequate airflow, as VFDs generate heat.

🏭 Product Applications

The Allen-Bradley 284D-FVD4P0D-10-CRW-3-DB is primarily used in distributed control architectures where the control device is mounted close to the motor. Typical applications include:

• Conveyor Systems: Providing variable speed control for material handling, synchronizing different conveyor sections, and using the braking feature for quick stops.

• Food and Beverage Processing: Utilized in washdown areas thanks to its IP67/NEMA 4 rating.

• Packaging Machinery: Offering precise speed control for improved throughput and packaging accuracy.

• Automated Assembly Lines: Controlling motor speed for indexing, positioning, and synchronized movement.

• Pumps and Fans (Decentralized): Where control is needed at the pump or fan location in a remote or harsh environment.
