20C-DPI1 | Allen Bradley | PowerFlex 700H DPI Option Board

Product Overview

The Allen Bradley 20C-DPI1 functions as the primary Drive Peripheral Interface (DPI) communication link for the PowerFlex 700H high-power AC drive series. This internal option board enables high-speed data exchange between the drive's control circuitry and external peripheral devices such as Human Interface Modules (HIMs), communication adapters, and PC-based configuration tools. We offer this component as 100% Brand New original stock, providing an essential solution for maintaining and optimizing large-scale motor control systems.

Technical Specifications

The 20C-DPI1 utilizes a compact, low-power architecture designed for direct integration into the PowerFlex 700H control pod.

Engineering Advantages

• Seamless Peripheral Synchronization: The 20C-DPI1 manages the data flow for up to five simultaneous DPI peripheral connections. It ensures that real-time parameters, fault codes, and diagnostic data synchronize instantly between the drive and the operator interface.

• Plug-and-Play Integration: The board features a direct-mate connector that eliminates the need for internal wiring harnesses. Technicians simply seat the board into the designated slot on the PowerFlex 700H control board, reducing the risk of wiring errors and accelerating commissioning times.

• Enhanced System Diagnostics: By enabling a high-bandwidth DPI link, this board allows for deep-level drive analysis through Connected Components Workbench (CCW) or DriveExplorer. It provides access to the full drive parameter set, which is critical for fine-tuning high-torque industrial applications.

• Rigid Noise Immunity: The 20C-DPI1 incorporates localized shielding to protect data integrity against the intense Electromagnetic Interference (EMI) typically found inside high-horsepower VFD enclosures. This ensures stable communication even when the drive operates at high switching frequencies.

FAQs

• Does the 20C-DPI1 require a separate power supply?

  No. The module draws all necessary operating power directly from the PowerFlex 700H main control board via the mounting pins. This simplifies the hardware footprint within the drive cabinet.

• Can I use this board in a standard PowerFlex 700 or 700S drive?

  The 20C-DPI1 specifically fits the 700H (High Power) frame architecture. While other PowerFlex 700 series drives use similar DPI technology, you must verify the specific hardware revision and slot compatibility of your drive before installation to avoid mechanical mismatch.

• Does this board support external communication protocols like EtherNet/IP?

  The 20C-DPI1 acts as the internal bridge to the drive's peripheral ports. To connect to an EtherNet/IP or ControlNet network, you must plug a compatible communication adapter (such as a 20-COMM-E) into the DPI port enabled by this board.

• How do I verify if the 20C-DPI1 is functioning correctly?

  Check the drive's "Port Status" parameters via the HIM. If the drive recognizes the board, the corresponding port will show an "Active" status, allowing you to configure attached peripherals and view real-time drive telemetry.
