150-F108NCD Industrial Automation Module by Allen-Bradley

Product Overview

The Allen-Bradley 150-F108NCD is a solid-state smart motor controller from the SMC-Flex series, engineered for precise microprocessor-based starting and stopping of 3-phase induction motors in demanding industrial environments. This Industrial Automation Module comes in an open-type enclosure and delivers robust performance with a current rating of 108 Amps and 75 Horsepower at 460V AC. Its input line voltage range of 200-575V AC, 3-phase, 50/60 Hz, combined with a control voltage of 100-240V AC, makes it a versatile choice for global applications.

Technical Specifications

The 150-F108NCD supports seven distinct starting and stopping modes, offering flexibility to match application requirements. Its power circuit tolerates -15% to +10% voltage variation and withstands 2,200V AC dielectric stress. With a maximum short-circuit rating of 30kA and built-in DV/DT protection via an RC network, this controller ensures reliable operation even in harsh electrical environments.

Integrated Protection and Diagnostics

This smart controller provides programmable protection against stalling, jamming, undervoltage, overvoltage, phase reversal, and overload conditions. It also implements electronic motor overload protection using the I2T algorithm. LED indicators display controller status, and the built-in DPI communication interface allows connection to multiple communication modules for seamless integration into plant networks.

Environmental and Physical Durability

The 150-F108NCD operates within a functional temperature range of 23 to 122°F and can be stored from 23 to 104°F with non-condensing 5% to 95% relative humidity. It withstands 1G peak vibration, 15G operating shock for 11 milliseconds, and operates without derating at altitudes up to 2000 meters. The controller holds CE, UL, cUL-us, and CCC certifications, ensuring compliance with international standards.

Installation and Setup Guidance

When installing the 150-F108NCD, ensure the enclosure provides adequate ventilation and protection from contaminants, as the open-type design requires a suitable cabinet. Verify that the input line voltage matches the 200-575V AC range and that the control voltage is within 100-240V AC. Properly torque all power and control wiring connections to avoid overheating. Configure the starting and stopping modes via the built-in interface to match your motor and load characteristics.

Maintenance and Reliability

Routine inspection of the 150-F108NCD should include checking for loose connections, signs of overheating, and accumulation of dust. Verify that the ambient temperature remains within the specified functional range. Periodic testing of protective functions ensures continued reliability and extends the service life of both the controller and the connected motor.

Compatibility and Integration

The 150-F108NCD integrates easily with existing motor control centers and automation systems. Its DPI communication interface supports multiple communication modules, allowing connection to PLCs and SCADA systems via protocols such as DeviceNet, ControlNet, or EtherNet/IP (using optional modules). This flexibility makes it an ideal upgrade path for older electro-mechanical starters.

Selection Guide and Purchasing Advice

Before purchasing the 150-F108NCD, verify that your motor's full-load current does not exceed 108 Amps and that the supply voltage is within the 200-575V AC range. Confirm the required control voltage (100-240V AC) and ensure your cabinet can accommodate the open-type enclosure.
