Allen-Bradley 150-F85NBD SMC Flex Smart Motor Controller Overview

Product Introduction

When managing motor stress from high inrush currents and abrupt starts, the Allen-Bradley 150-F85NBD SMC Flex Smart Motor Controller provides a reliable solid-state solution. This programmable motor starter protects against current and voltage surges while enabling smooth acceleration and deceleration. Part of the SMC-Flex family, the 150-F85NBD is designed for three-phase induction motors and offers multiple starting modes to suit diverse industrial applications.

Technical Specifications Breakdown

The 150-F85NBD operates with an input line voltage of 200 to 460 Volts AC, three-phase, 50/60 Hertz. Its control voltage ranges from 100 to 240 Volts AC (for 5 to 480 A units). The controller delivers a rated current output of 85 amperes and provides 60 Horsepower at 460 Volts AC. It features an open enclosure type with an IP00 protection rating, meaning it requires installation within a suitable cabinet. Physical dimensions are 321 mm x 150 mm x 203 mm (height x width x depth), and the unit weighs 5.7 kg. Power dissipation is 129 Watts, which affects internal temperature management.

Industry Applications

This SMC Flex controller excels in applications requiring controlled motor starting and stopping, such as conveyors, pumps, fans, and compressors. The 150-F85NBD supports soft start and stop, full voltage, dual ramp start, current limit start, selectable kickstart, and slow speed modes. For example, in a pumping station, the soft start mode reduces mechanical stress and water hammer, extending equipment life. The controller also includes Smart Motor Braking (SMB) with per-phase CT and Accu-stop mode for precise stopping.

Installation & Setup Guidance

Mount the 150-F85NBD vertically with a minimum vertical clearance of 15 cm (6 inches) for proper airflow. For power wiring, use 2.5 to 85 mm² (#14 to 3/0 AWG) wire; for control wiring, use 0.75 to 2.5 mm² (18 to 14 AWG). The maximum allowable conductors per control terminal is two wires. The controller supports line connection with isolation transformer (default), delta connection with isolation contactor, and delta connection with shorted SCR protection as optional modes. Programming is performed via the front 5-button keypad using sequential keystrokes.

Compatibility & Integration

The 150-F85NBD integrates with various communication networks when an appropriate adapter is installed, including DeviceNet, Interbus, Allen-Bradley Remote I/O, ControlNet, EtherNet, and Profibus. It features built-in DPI communication capabilities and network I/O. The controller also includes integrated electronic motor overload protection, short-circuit and thermal protection circuitry, stalling and jamming detection, undervoltage and underload protection, voltage unbalance monitoring, and excessive starts per hour protection.

Selection Guide & Purchasing Advice

Before purchasing the 150-F85NBD, verify that your motor's full-load current does not exceed 85 amps and that the supply voltage matches the 200-460VAC three-phase range. The open enclosure requires installation in a clean, dry environment or within a suitable cabinet.
