Beckhoff EL6731 EtherCAT PROFIBUS Master Terminal

$0.00

Beckhoff EL6731 is an EtherCAT communication terminal that integrates PROFIBUS master functionality directly into a Beckhoff EtherCAT I/O station. It allows modern TwinCAT/EtherCAT control systems to operate and diagnose existing PROFIBUS DP, DP-V1, and DP-V2 field devices without a separate PCI fieldbus card.

This page is for the exact manufacturer reference EL6731. Corwin Solutions creates exact model-level listings because industrial hardware within the same family can look almost identical while differing in network protocol, electrical rating, firmware, memory, safety function, mechanical fit, accessories, or lifecycle status.

Key product details

  • Manufacturer: Beckhoff
  • Model: EL6731
  • Product type: EtherCAT PROFIBUS master terminal
  • Fieldbus: PROFIBUS DP / DP-V1 / DP-V2
  • Role: PROFIBUS master
  • Fieldbus channels: 1
  • Transmission rate: 9.6 kbit/s to 12 Mbit/s
  • Interface: 9-pin D-sub, galvanically isolated
  • Maximum slaves: Up to 125
  • Process image: Up to approximately 1.4 kB input and 1.4 kB output
  • Electrical isolation: 500 V E-bus to PROFIBUS
  • Configuration: TwinCAT
  • Diagnostics: Status LEDs and fieldbus diagnostics

Common applications Typical applications include retrofitting legacy PROFIBUS drives and remote I/O into EtherCAT machines, machine upgrades, process equipment, packaging systems, motion installations, and plants transitioning from PROFIBUS to EtherCAT without replacing every field device at once.

Compatibility and ordering note: Confirm that the installed terminal is the EL6731 master and not the EL6731-0010 slave version. Verify PROFIBUS baud rate, node count, GSD files, DP-V1/DP-V2 functions, process-image size, TwinCAT project, bus termination, connector pinout, diagnostics, and any isochronous motion requirements before replacement.

Why this part is commonly sourced: Buyers and maintenance teams may need the exact model to restore a failed production asset, preserve an installed OEM platform, build strategic spare inventory, support an obsolete machine, complete a BOM, or avoid unnecessary redesign and commissioning during a time-sensitive repair.

Need EL6731? Send Corwin Solutions the required quantity, preferred condition, ship-to destination, and delivery deadline. For replacement requests, include a clear photo of the existing nameplate plus any known series, firmware, network, motor, HMI project, terminal, safety, or option information. Availability, condition, exact configuration, lifecycle context, and lead time are confirmed at quotation.
