EL2004 Beckhoff EtherCAT 4-channel Digital Output Terminal Module
24VDC
The Beckhoff EL2004 is a compact and robust 4-channel digital output terminal in the EtherCAT Terminals (EL) series, designed for reliable
switching of actuators, solenoids, indicator lights, relays, and
other 24 V DC loads in industrial automation systems. With a high
output current of 2 A per channel and support for EtherCAT real-time communication, the EL2004 delivers exceptional performance, fast response times,
and seamless integration into Beckhoff TwinCAT-based control
architectures—making it ideal for machine building, packaging,
robotics, and process control applications.
