Product Description P/N: EL6021
Description
The Beckhoff EL6021 is a single-channel EtherCAT terminal designed to interface devices using RS422 or RS485 serial communication. Operating independently of the fieldbus system, it supports full- or half-duplex data transmission up to 115.2 kbaud. Its differential signal transmission and electrical isolation enhance interference immunity for reliable serial communication.

Information About EL6021
The EL6021 belongs to the Beckhoff EtherCAT I/O system, offering robust serial communication capabilities within compact terminal housing. It is designed to connect RS422/RS485 field devices directly to an EtherCAT coupler without requiring external converters. With 864-byte receive and 128-byte transmit buffers, the terminal efficiently handles serial data streams and supports configuration directly through the PLC. Typical applications include linking measurement devices, sensors, controllers, and industrial communication equipment that require long-distance, noise-resistant serial links.
Key Features:
- RS422/RS485 support: One serial channel for differential full- or half-duplex communication.
- Wide baud rate range: Operates from 2400 to 115,200 baud with a 9600-baud default.
- Electrically isolated design: 500 V isolation between E-bus and signal voltage.
- Long-distance capability: Supports up to 1000 m cable length with twisted pair wiring.
- Integrated buffers: 864-byte receive and 128-byte transmit buffers for smooth data handling.
- Compact EtherCAT terminal: 12 mm width for space-efficient DIN-rail installations.
- Pluggable wiring: Compatible with ES-series wiring modules for easy termination.
- Industrial resilience: Rated IP20 with –25…60°C operating range.
The EL6021 delivers the reliability and precision required for industrial RS422/RS485 serial communication within EtherCAT automation systems.
