Here are some key features of the EL2004 module:

Number of Outputs: The EL2004 module provides four digital outputs. Each output can be configured as a high-side or low-side switch.

Output Current: The module supports continuous output currents of up to 0.5 A per channel. The total output current should not exceed 2 A.

Power Supply: The EL2004 module requires a 24 V DC power supply, which is typically provided by the EtherCAT fieldbus system.

Diagnostic LEDs: The module includes diagnostic LEDs that provide status information for power supply, communication, and individual output channels.

EtherCAT Fieldbus: The EL2004 module communicates over the EtherCAT fieldbus, a high-speed industrial Ethernet protocol developed by Beckhoff. It offers real-time communication with precise synchronization of devices.

Software Configuration: The EL2004 module is configured and controlled using Beckhoff's TwinCAT automation software. TwinCAT provides a comprehensive set of tools for programming, testing, and monitoring PLC (Programmable Logic Controller) applications.
