PowerFlex | Allen Bradley 20-COMM-D DeviceNet Communication Adapter

Product Overview

The Allen Bradley 20-COMM-D acts as a high-speed communication bridge between PowerFlex 7-Class AC drives and DeviceNet networks. This adapter enables seamless integration of motor controllers into plant-wide control architectures, allowing for real-time parameter adjustment and diagnostic monitoring. We supply this component in 100% Brand New original condition, ensuring flawless data synchronization for your PowerFlex architecture.

Technical Specifications

This adapter utilizes the Drive Peripheral Interface (DPI) protocol to facilitate high-speed internal communication with the host drive.

Engineering Advantages

• Broad Hardware Compatibility: The 20-COMM-D supports a vast range of hardware including PowerFlex 700 series drives and SMC-50 smart motor controllers. This versatility allows facilities to standardize their communication hardware across multiple motor control types.

• Rapid Response Times: With a minimum Requested Packet Interval (RPI) of 5 ms, the adapter provides the high-speed feedback necessary for precision torque and speed control loops.

• Simplified Diagnostics: Three dedicated LED indicators provide instant visual verification of the drive connection, adapter health, and network status. This reduces troubleshooting time during commissioning or network interruptions.

• Low Power Footprint: The module draws only 150 mA from the host drive, minimizing the thermal load on the drive’s internal power supply and maintaining system efficiency.

FAQs

• Does this adapter require an external power supply?

  The host drive powers the internal circuitry via the DPI connector, while the DeviceNet network provides 24V DC (60 mA) specifically for the network transceiver. You must ensure the DeviceNet cable carries active power for the adapter to communicate with the scanner.

• How do I set the node address and data rate?

  You can configure the node address and baud rate either through the host drive’s HIM (Human Interface Module) or via software tools like DriveExplorer or Connected Components Workbench.

• Can I use the 20-COMM-D with the PowerFlex 750 series?

  Yes. The 20-COMM-D maintains compatibility with the PowerFlex 750 series, provided you use the appropriate communication carrier or slot designated for DPI legacy modules.

• Is this a refurbished or used unit?

  No. We guarantee this 20-COMM-D is 100% Brand New and arrives in original factory packaging. This ensures the unit has never been exposed to industrial contaminants or electrical stress prior to your installation.
