Allen-Bradley 150-F317NCR SMC-Flex Solid State Controller 317A

Product Overview

The 150-F317NCR is part of the Allen-Bradley SMC-Flex product line, known for its smart motor control capabilities. It features an open enclosure, a controller rating of 317 A and 250 HP at 460V AC, and supports a three-phase input line voltage of 200-575V AC at 50 and 60 Hz. The control voltage is 24V AC/DC (for 5-480 A units). This controller is designed to work with Wye-delta motors, six-lead motors, and standard squirrel-cage induction motors, offering multiple starting and stopping modes including soft start, current limit start, dual ramp start, and linear speed acceleration.

Technical Specifications Breakdown

Key parameters for the 150-F317NCR are listed below for quick reference:

Industry Applications

For example, in pumping stations, the soft start and soft stop modes reduce water hammer and mechanical stress. In conveyor systems, the dual ramp start allows smooth acceleration under varying loads. The 150-F317NCR also supports linear speed acceleration, beneficial for applications like crushers or mixers where gradual speed changes improve process control and equipment life.

Installation & Setup Guidance

Install the 150-F317NCR in a clean, dry environment with adequate ventilation. Ensure the input line voltage matches the 200-575V AC, 3-phase supply. The control voltage requires 24V AC/DC. For fan operation, provide a single-phase power supply of 120 or 240V AC. Mount the open enclosure securely, and connect motor leads according to the motor type (Wye-delta, six-lead, or squirrel-cage). Program the starting mode via the front keypad and backlit LCD display. Verify all connections before powering up.

Maintenance & Reliability

Periodically inspect the controller for dust accumulation and ensure the ambient temperature stays within -5 to 50 °C (23 to 122 °F) during operation. The non-operating temperature range is -20 to 75 °C (-4 to 167 °F). Check for fault indications such as undervoltage, overvoltage, or overload on the LED status indicators. Keep the enclosure free of contaminants to maintain reliable performance.

Compatibility & Integration

The 150-F317NCR integrates with various motor types and control systems. It includes 4 programmable auxiliary contacts and 1 DPI port for communication. The front keypad and backlit LCD enable easy configuration. It detects faults like phase reversal, jam, stall, and communication faults, aiding system diagnostics.

Selection Guide & Purchasing Advice

When selecting the 150-F317NCR, verify that your motor's full-load current does not exceed 317 A and that the horsepower rating aligns with your application (250 HP at 460V AC). We offer genuine Allen-Bradley parts with expert support.
