Product Overview

The Allen-Bradley 20-750-20COMM functions as a specialized communication carrier card for the PowerFlex 750-Series variable frequency drive family. This interface card retrofits legacy 20-COMM communication adapters directly into modern PowerFlex 753 and PowerFlex 755 drive control pods. By providing a physical and electrical bridge, this module enables existing field networks—such as EtherNet/IP, DeviceNet, ControlNet, or Profibus—to interface with updated drive architectures. We deliver this essential drive accessory as 100% brand new, original factory stock to guarantee precise terminal alignment and seamless network synchronization.

Engineering Advantages

Seamless Network Legacy Protection: The carrier card bridges the generation gap between legacy network layouts and updated drive hardware. This configuration allows facilities to upgrade obsolete drives to PowerFlex 750 units without requiring a complete overhaul of existing fieldbus networks or costly reprogramming of supervisory PLC communication rungs.
Optimized Slot Space Preservation: Mounting the 20-750-20COMM card into the recommended Port 6 location keeps adjacent options slots completely clear. This prevents spatial interference inside the compact control pod and maintains unhindered cable routing for neighboring I/O cards or encoder feedback modules.
Secure Vibration-Resistant Mechanical Lock: The carrier kit includes precise standoffs and an integrated adapter plate. This rigid mechanical fastening mechanism prevents operational drive vibration from shifting the contact pins, ensuring consistent data bus connection stability inside heavy-vibration motor control centers.
Direct Integration into Drive Pod Logic: The module seats directly into the integrated main control backplane of the drive. The drive firmware recognizes the adapted 20-COMM module instantly upon power-up, minimizing configuration steps during commissioning.

FAQs

Can I install the 20-750-20COMM carrier card into a Frame 1 PowerFlex drive?

No. This standard 20-750-20COMM card exclusively fits Frame 2 and larger PowerFlex 750-Series drives. Frame 1 drives require a physically distinct variation with a different layout profile, designated under catalog number 20-750-20COMM-F1.
Why does Rockwell Automation explicitly recommend Port 6 for installation?

While the card can mechanically fit into Ports 4 or 5, doing so creates physical interference that blocks adjacent option slots and restricts routing for external communication cables. Installing the carrier in Port 6 optimizes space utilization inside the control pod.
Are there any specific safety precautions when using this card alongside a Profibus module?

Yes. When you install this carrier card immediately adjacent to a 20-750-PBUS Profibus module, the lower metal mounting screw can potentially contact the Profibus connector housing. You must follow the specialized spacing and insulation procedures outlined in the Rockwell manual to prevent electrical shorts.
