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, using differential signaling for high noise immunity. The interface is galvanically isolated from the E-bus. With the TwinCAT Virtual Serial COM Driver, the EL6021 can be used as a standard Windows COM port.

Key Features

  • RS422/RS485 serial interface (differential), full/half duplex
  • Data rates: 2400…115,200 baud (default 9600, 8 data bits, no parity, 1 stop bit)
  • Approx. 1000 m cable length with twisted pair; 120 Ω line impedance
  • Large buffers: 864-byte RX and 128-byte TX
  • 500 V electrical isolation between E-bus and signal voltage
  • Compact 12 mm IP20 terminal for 35 mm DIN rail

Applications

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