Product Specification

EL2004 Beckhoff EtherCAT 4-channel Digital Output Terminal Module 24VDC

1.Overview of the EL2004 Beckhoff

The Beckhoff EL2004 is a high-performance, compact EtherCAT digital output terminal block designed for industrial automation control systems. This module transmits binary 24V DC control signals from automation equipment to process-level actuators in an electrically isolated manner, acting as a crucial bridge between the supervisory control system and field actuators.

The EL2004 provides four independent output channels, each equipped with LED status indicators to display signal status in real time, facilitating on-site commissioning and fault diagnosis. Based on EtherCAT bus technology, it supports seamless integration with TwinCAT automation software, enabling high-speed, high-precision distributed control.

1. Powerful Load Driving Capability

Supports various load types: resistive loads, inductive loads (such as solenoid valves and relays), and lighting loads, offering extremely high application flexibility.
Maximum output current per channel reaches 0.5 A, directly driving various industrial actuators without the need for additional intermediate relays.

2. Comprehensive Protection Mechanisms
Short-circuit protection: When a short circuit occurs at the output, the module automatically limits the current (typical short-circuit current < 2 A) to prevent damage.
Reverse polarity protection: Effectively prevents equipment damage caused by incorrect field wiring.
Low breaking energy: < 150 mJ per channel, ensuring safe shutdown in fault conditions.

3. High-Speed ​​Response Performance
Fast switching time: Typical on (TON) value 60 µs, typical off (TOFF) value 300 µs, meeting high-precision timing control requirements.
Supports XFC (eXtreme Fast Control) timestamp function, enabling microsecond-level synchronization of process data.

4. Modular and Easy-to-Use Design
Compact structure: 12 mm ultra-thin housing, supports standard DIN. DIN rail mounting saves control cabinet space.
Configuration-free design: No address or parameter settings required, plug and play, significantly reducing commissioning workload.
Electrical isolation: 500V (E-bus/field potential) isolation voltage effectively resists field interference.
Pluggable wiring: The ES2004 model supports pluggable wiring layers for easy maintenance and replacement.
