Description

The BECKHOFF ER2028-0002 is an industrial-grade EtherCAT Box designed for decentralized automation architectures. Operating directly in the field without the need for a protective control cabinet, this module provides 8 digital outputs to interface with actuators, indicators, and other digital control devices. Its rugged zinc die-cast enclosure makes it highly resilient to harsh physical and environmental conditions.

This module handles digital output signals with a nominal voltage of 24 V DC and can deliver a maximum output current of 2.0 A per channel. Built-in protection mechanisms make each channel short-circuit proof, safeguarding connected equipment and the module itself from electrical faults. The unit connects to the EtherCAT network via shielded, screw-type M8 connections, ensuring high signal integrity and fast fieldbus communication.

For power distribution, the BECKHOFF ER2028-0002 features integrated power feed and downstream connection points using M8 connectors. This configuration allows convenient daisy-chaining of system and load voltage across multiple EtherCAT Box modules. The physical housing provides high environmental protection ratings, allowing versatile physical orientation during installation.

Features

  • 8 digital outputs capable of switching up to 2.0 A per channel
  • Short-circuit proof output design with electrical isolation up to 500 V
  • Ohmic, inductive, and lamp load compatibility
  • M12 output connections (5-pin, a-coded)
  • Heavy-duty zinc die-cast housing designed for direct field mounting
  • M8 shielded screw-type connectors for EtherCAT bus interface
  • M8 system and auxiliary power distribution (feed and downstream)

Applications

  • Decentralized digital actuator control in automated assembly lines
  • Direct machine-mount switching of inductive valves, solenoids, and contactors
  • Control of status indicators and signaling lamps in harsh environments
  • Distributed I/O systems requiring IP67-rated protection without control cabinets

Installation Guidelines

  1. Verify the exact model number ER2028-0002 before proceeding with installation.
  2. Isolate all system and auxiliary power supplies feeding the equipment.
  3. Mount the zinc die-cast housing securely to a flat mounting surface using two M3 screws through the 3.5 mm diameter fixing holes.
  4. Connect the EtherCAT communication lines to the M8 sockets, tightening the screw-type connections to maintain the specified IP protection level.
  5. Connect the load actuators using M12 5-pin a-coded cabling, ensuring the sealing rings are correctly positioned and tightened.
  6. Attach the M8 power feed cabling, ensuring proper polarity and correct voltage levels for the system (US) and load (UP) power paths.
  7. Restore power and configure the fieldbus module within your TwinCAT programming environment.
