Allen-Bradley 25B-D037N114

The Allen-Bradley 25B-D037N114 is an adjustable frequency AC Drive from Rockwell Automation, designed for industrial applications. This drive is known for its compact design, making it ideal for installations with limited panel space. It offers versatile motor control capabilities, ensuring efficient operation in various settings.

Technical Specifications:

The 25B-D037N114 operates at a voltage rating of 480VAC and supports three-phase power systems. It has an output power of 18.5 kW (25.0 HP) for normal duty and 15.0 kW (20.0 HP) for heavy-duty applications, with an output current of up to 37.0 Amperes.

The drive features an IP20 NEMA open-type enclosure and a filtered emission class. It includes an integral keypad for local operation, which can also configure and troubleshoot the drive.

Additionally, it has seven sink/source discrete inputs, one N.O. contact relay output, one N.C. contact relay output, two digital/optocoupler discrete outputs, two 0-10VDC or 0-20mA analog inputs, and one 0-10VDC or 0-20mA analog output. The embedded Ethernet/IP and RS-485 communication interfaces enable seamless integration with Programmable Automation Controllers (PACs), HMIs, and SCADA systems.

Safety Precautions and Measures:

Safety is necessary when working with the Allen-Bradley 25B-D037N114. Before installation, ensure the drive is completely disconnected from all power sources. The capacitors in the drive can hold a charge even after power is removed, so waiting at least three minutes is essential to allow the capacitors to discharge fully. Only qualified personnel should handle the drive to avoid personal injury or equipment damage.

Installation Guide:

First, install the drive vertically on a flat, secure surface to ensure proper cooling and airflow. Maintain a minimum clearance of 50 mm (2 inches) on all sides. The drive’s compact design supports zero stacking, which saves panel space. Then, follow the wiring instructions in the user manual. Use suitable wire sizes for power and control connections.

Ensure the input power supply (L1, L2, L3) and motor leads (T1, T2, T3) are securely connected. Proper grounding is required for safety and to minimize electrical noise. After this, connect the drive’s ground terminal to the system ground using an appropriately sized conductor. This is essential to ensure safety and reduce electrical noise.

Use the integral keypad or Rockwell Software’s Connected Components Workbench to configure the drive. Set the motor control parameters, such as voltage, current, and frequency, according to the motor’s specifications. The keypad also facilitates troubleshooting by displaying diagnostic information. After installation, perform a test run to make sure the drive and motor operate correctly. Adjust parameters as necessary to optimize performance.
