Product Description

The 80190-440-03-R serves as the critical communication and control bridge within an Allen-Bradley Soft Starter. Its primary function is to act as the Interface Board that manages the firing signals for the SCRs (Silicon Controlled Rectifiers) and coordinates data between the power section and the main control module. The “R” suffix typically denotes a revised or “Renewable” part, often used in maintenance and repair of high-horsepower motor control units.

Product  Parameters

Product Advantages

• Precision Motor Control: Facilitates advanced starting modes such as Soft Start, Selectable Kickstart, and Pump Control by ensuring precise SCR firing.

• Integrated Diagnostics: The board helps monitor thermal conditions and electrical faults, feeding real-time data to the controller’s display or network.

• Modular Repair: Instead of replacing an entire 150-F series soft starter, users can replace this specific board to restore functionality, significantly reducing repair costs.

• High Durability: Engineered to withstand the electrical noise and thermal cycling typical of heavy-industrial motor starting applications.

Safety and Maintenance

• Lethal Voltage Hazard: This board is connected directly to the power structure of the soft starter. Wait at least 5 to 10 minutes after disconnecting power to allow internal capacitors to discharge before servicing.

• ESD Protection: The PCB contains highly sensitive CMOS components. Always use a grounded anti-static wrist strap and handle the board by the edges only.

• Gate Lead Connection: Ensure that the gate leads connected to the SCRs are seated firmly. Loose connections can lead to unbalanced phases or SCR failure.

• Firmware Compatibility: When replacing this board, verify that it is compatible with the existing control module’s firmware version to avoid communication errors.

Typical Applications

• Heavy-Duty Industrial Pumps: Used in water treatment and irrigation where controlled acceleration is required to prevent “water hammer.”

• Compressors and Fans: Managing the high inrush current of large centrifugal loads in HVAC and manufacturing.

• Conveyor Systems: Providing smooth starts for long belts to prevent mechanical shock and material spillage.

• Crushers and Grinders: Facilitating current-limit starts for high-inertia loads in mining and aggregate industries.
