150-F85NBDD Industrial Automation Module by Allen-Bradley

Product Overview

When motor starting demands precision and protection, the Allen-Bradley 150-F85NBDD Smart Motor Controller delivers. This solid-state, low-voltage soft starter from the SMC-Flex family provides microprocessor-controlled starting for standard 3-phase induction motors, ensuring smooth acceleration and reducing mechanical stress.

The 150-F85NBDD is rated at 460 Volts AC (3-phase), 85 Amps, and 60 Horsepower, making it ideal for a wide range of industrial applications. Its open-controller design features a 5-button front-panel keypad and a built-in LCD screen for straightforward programming and diagnostics.

Technical Specifications

Key parameters of the Allen-Bradley 150-F85NBDD are listed below:

Key Features and Benefits

• Built-in SCR bypass: After the starting algorithm completes, the SCR bypass ensures smooth, efficient operation without additional power loss.
• Comprehensive motor protection: Includes underload protection, jam detection, stall protection, over-voltage and under-voltage protection, voltage unbalance protection, and electronic motor overload protection.
• Flexible communication: The integral DPI communication interface allows easy connection to HMI modules and a wide range of communication modules.
• Multiple operation modes: Offers 8 standard operating modes plus optional smart motor braking for applications requiring faster stopping than normal coast-to-rest.
• User-friendly interface: The 3-line by 16-character LCD display and 5-button keypad simplify parameter programming, control, diagnostics, and troubleshooting.

Industry Applications

The 150-F85NBDD is well-suited for conveyors, pumps, fans, and compressors where controlled starting reduces wear on mechanical components and prevents voltage sags. For example, in a pumping station, the soft starter gradually ramps up the motor to full speed, minimizing water hammer and extending pump life. In a conveyor system, it ensures smooth acceleration of heavy loads, reducing belt stress and product spillage. The optional braking control is particularly valuable in applications like machine tools where rapid stopping improves cycle times.

Installation and Setup Guidance

Before installation, verify that the line input voltage matches the 460 Volts AC rating and that the control voltage is within 200 to 230 Volts AC. Mount the controller in a clean, dry enclosure with adequate ventilation to maintain ambient temperature within the manufacturer's specifications. Connect the three-phase power leads to the designated terminals, ensuring proper torque. Configure the auxiliary contacts using the front-panel keypad to assign functions such as network, alarm, up-to-speed, normal, or fault control. For initial startup, use the LCD display to navigate the programming menu and set the appropriate starting mode and parameters for your application.

Maintenance and Reliability

Routine maintenance is essential to maximize the service life of the 150-F85NBDD. Inspect the controller periodically for dust buildup on heatsinks and ensure all connections remain tight. Check the auxiliary contacts for wear if they are used frequently. Since the controller includes built-in protection features, it helps prevent motor damage, reducing unscheduled downtime and repair costs. By maintaining the controller, you extend its operational life and preserve the efficiency of your motor control system.

Compatibility and Integration

The 150-F85NBDD features built-in DPI communication capability, allowing integration with a range of Allen-Bradley HMI modules and communication modules. This flexibility enables remote monitoring and control, making it easy to incorporate the soft starter into existing automation networks. The four fully programmable auxiliary contacts provide additional integration options for signaling and interlocking with other control system components.

Selection Guide and Purchasing Advice

When selecting a replacement or new soft starter, verify that the voltage, current, and horsepower ratings match your motor requirements. The 150-F85NBDD is rated for 460V AC, 85A, and 60HP, making it suitable for many mid-size motors. Additionally, confirm that your control system is compatible with the DPI communication interface.
