Allen-Bradley 150-F85NBDB SMC Flex Soft Starter Controller

Product Overview

The Allen-Bradley 150-F85NBDB is a low-voltage solid state controller from the SMC-Flex series. It provides digitally-controlled starting with flexible parameter programming, control, diagnostics, and troubleshooting via a 3-line by 16-character LCD display and a 5-button front panel keypad. This controller is designed to reduce mechanical stress and electrical disturbances during motor startup.

Technical Specifications Breakdown

Key parameters for the 150-F85NBDB are listed below for quick reference:

Industry Applications

It also suits conveyors, fans, and compressors that benefit from Linear Speed Acceleration, Soft Start, and Current Limit modes. The 4 programmable auxiliary contacts allow integration into complex control systems for fault, alarm, or at-speed indication.

Installation & Setup Guidance

Mount the controller in a clean, dry enclosure with adequate ventilation. Ensure the line input voltage matches the 460 Volt AC rating and the control voltage is within 200 to 230 Volts AC. Use the 5-button keypad and LCD to configure operating modes such as Soft Start, Full Voltage Start, or Dual Ramp Start. Connect the DPI communication port to Allen-Bradley Bulletin 20 HMI modules for remote monitoring.

Maintenance & Reliability

Periodically inspect the heatsink fan and RC snubber network for dust accumulation. Verify that the metal oxide varistors (220 J) are intact for transient protection. Check the auxiliary contact operation and ensure the control circuit voltage remains stable. The built-in overload, underload, stall, and jam detection features help prevent motor damage.

The Evolution of Industrial Motor Control

Industrial motor control has evolved from simple electromechanical starters to sophisticated digital controllers that optimize performance and protect equipment. The Allen-Bradley 150-F85NBDB SMC Flex soft starter represents this advancement, offering precise control and diagnostics for three-phase induction motors in demanding environments.

Compatibility & Integration

The 150-F85NBDB includes built-in DPI communication capability with a serial interface, supporting connection to Allen-Bradley HMI modules and communication modules. It integrates with standard fuse, circuit breaker, and high capacity time delay Class CC/J/L short-circuit protection devices. The controller works with both line-connected and delta-connected motors up to 85A and 147A respectively.

Selection Guide & Purchasing Advice

When selecting the 150-F85NBDB, verify that your motor's full-load current and horsepower match the 85 Amp and 60 HP ratings. Confirm the line voltage is 460 Volt AC and the control voltage is available at 200 to 230 Volts AC. AutoDCSTech offers this controller with fast shipping and expert support.
