Overview

The Beckhoff EL6021 is a 1‑channel serial communication EtherCAT Terminal for RS422/RS485 devices. It operates independently of the higher‑level bus in full‑ or half‑duplex mode up to 115.2 kbaud and provides galvanic isolation between E‑bus and signal lines. With the TwinCAT Virtual Serial COM Driver, the EL6021 can be used as a standard Windows COM interface.

Key Features

  • RS422/RS485 serial interface (differential signaling)
  • Data rates 2400…115,200 baud (default 9600, 8N1)
  • Full- or half‑duplex operation; line impedance 120 Ω
  • Approx. 1000 m cable length with twisted pair (application dependent)
  • Receive/transmit buffers: 864 bytes RX, 128 bytes TX
  • 500 V electrical isolation (E‑bus/signal voltage)

Applications

  • Connecting RS422/RS485 sensors, drives, and serial peripherals to EtherCAT systems
  • PC communication via TwinCAT Virtual Serial COM Driver
