150-B97NBDC-8B Allen Bradley

Description

Product Name:  150-B97NBDC-8B Allen Braley Input module

Product details:  

The Allen-Bradley 150-B97NBDC-8B is a high-performance SMC-Delta Smart Motor Controller. Part of the SMC-2 and SMC-Delta family, this solid-state controller is designed to provide smooth acceleration and deceleration for three-phase motors, specifically targeting applications where space and cost-efficiency are priorities.

Product Detailed Description

The 150-B97NBDC-8B is an open-style motor controller featuring integrated bypass circuitry. This means that once the motor reaches full speed, internal contactors take over the load, reducing heat generation and extending the life of the solid-state components.

It is specifically designed for Delta-connected motors, allowing for a smaller controller footprint relative to the motor’s horsepower. It utilizes microprocessor-controlled SCRs (Silicon Controlled Rectifiers) to provide precise control over motor torque and current during start-up.

Technical Specifications

Product Advantages

• Reduced Mechanical Stress: By providing a “soft start,” it prevents the sudden torque spikes associated with across-the-line starting, protecting belts, gears, and couplings.

• Thermal Efficiency: The built-in bypass contactors minimize power dissipation during steady-state operation, reducing the need for external cooling.

• Space Saving: The SMC-Delta design allows for a more compact installation compared to traditional Star-Delta (Wye-Delta) starters.

• Adjustable Start Modes: Features multiple start modes (such as Soft Start and Current Limit) to match the specific needs of different mechanical loads.

• Cost-Effective: Combines power electronics and bypass functionality in a single unit, reducing wiring complexity and component count.

Important Considerations & Warnings

• Heat Dissipation: Although it has a bypass, the unit generates heat during the starting phase. Ensure adequate ventilation and clearance within the electrical cabinet.

• Line Voltage Compatibility: Confirm that your supply voltage matches the 480V rating; using this on 600V systems will damage the unit.

• Heatsink Grounding: Ensure the unit is properly grounded to the sub-panel to prevent electrical noise and ensure safety.

• Phase Rotation: Always verify phase rotation before commissioning to avoid reverse motor rotation, which could damage connected equipment.

Common Applications

This controller is ideal for applications requiring a balance of high starting torque and smooth acceleration:

• Centrifugal Pumps: Prevents “water hammer” effects in piping systems.

• Conveyor Systems: Avoids product tipping or belt slipping during start-up.

• Fans and Blowers: Reduces the high inertia stress on large industrial fans.

• Compressors: Allows for a controlled start to reduce current peaks on the electrical grid.
