150-A35NBDE Allen‑Bradley

Description

Product Name : 150-A35NBDE Allen Braley Output module

Product details:

The Allen-Bradley 150-A35NBDE is a member of the SMC-2 series of Smart Motor Controllers. Designed by Rockwell Automation, these compact, solid-state controllers provide a cost-effective solution for starting standard 3-phase squirrel-cage induction motors while reducing mechanical stress and current surges.

1. Product Description

The 150-A35NBDE is a micro-processor-based smart motor controller that offers three distinct modes of operation: Soft Start, Current Limit Start, and Full Voltage Start. Its compact “open type” design is ideal for space-constrained industrial control panels. It features integrated bypass circuitry to minimize heat generation during steady-state operation.

2. Technical Parameters

The following table highlights the core technical specifications for this specific model:

3. Product Advantages

• Reduced Mechanical Stress: By providing a smooth ramp-up, the device prevents the “jerk” associated with across-the-line starting, extending the life of belts, gears, and bearings.
• Energy Efficiency: The internal bypass feature engages once the motor reaches full speed, reducing power dissipation and the need for external cooling.
• Compact Footprint: Its small size allows it to replace traditional star-delta starters or bulky autotransformers in existing panels.
• Easy Setup: Configuration is handled via simple DIP switches and rotary potentiometers, requiring no complex programming software for basic operation.

4. Key Features & Operating Modes

• Soft Start: Gradually increases voltage over a timed period (selectable from 2 to 30 seconds).
• Current Limit Start: Limits the maximum starting current to a pre-set level (selectable from 200% to 450% of full load).
• Full Voltage Start: Provides traditional across-the-line starting performance when needed.
• Soft Stop: Extends the deceleration time, which is particularly useful for pumping applications to prevent “water hammer” effects.

5. Precautions & Installation Notes

Note: Installation and maintenance should only be performed by qualified personnel familiar with solid-state motor control technology.

1. Branch Circuit Protection: The controller must be protected by appropriately rated fuses or circuit breakers to prevent damage during a short-circuit event.
2. Heat Dissipation: Ensure adequate clearance around the unit within the enclosure to allow for natural convection, even though the bypass reduces heat.
3. Isolation: Solid-state starters do not provide electrical isolation. A formal disconnect or isolation contactor must be used for safety during motor maintenance.
4. Voltage Matching: Ensure the control voltage (24V AC/DC) matches the specific suffix of your model to avoid damaging the logic board.

6. Common Applications

The 150-A35NBDE is versatile and widely used in industries such as water wastewater, manufacturing, and HVAC. Typical applications include:

• Centrifugal Pumps: Smooth acceleration and deceleration to prevent fluid surges.
• Conveyor Belts: Preventing product tipping or belt slipping during startup.
• Fans and Blowers: Reducing the high torque loads on drive pulleys.
• Compressors: Minimizing the power grid “dip” often caused by large motor starts.
