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.
