Tutto sui PLC: la CPU
A practical engineering guide to PLC CPU operation, from deterministic scan cycles and I/O image tables to memory, communications, diagnostics, redundancy, processor sizing, and reliable system...
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.
