It integrates four independent digital output channels, each capable of switching up to 0.5 A with short-circuit protection and reverse polarity protection. The module provides electrical isolation between the E-bus and field potential, ensuring safe operation in industrial environments. It supports rapid switching times (60 µs ON / 300 µs OFF), making it suitable for high-speed automation tasks. With its compact 12 mm width and DIN-rail mounting design, the EL2004 enables high-density I/O configuration while maintaining excellent reliability and ease of integration into EtherCAT-based systems. Key Features: Four 24 VDC digital output channels: Supports ohmic, inductive, and lamp loads for broad application compatibility. High-speed switching performance: Provides typical switching times of 60 µs (TON) and 300 µs (TOFF). Built-in protection: Includes short-circuit proof outputs, reverse polarity protection, and up to 150 mJ/channel breaking energy. EtherCAT integration: Interfaces directly with the EtherCAT system via the E-bus with 500 V electrical isolation. Compact and efficient design: Only 12 mm wide, enabling high-density I/O deployments. LED indication per channel: Provides real-time output status for easy diagnostics. Rugged environmental performance: Operates from −25°C to +60°C and handles 95% humidity without condensation. Zero configuration required: Automatically recognized by the EtherCAT master with no address setting needed. The EL2004 delivers the reliability and fast response required for modern EtherCAT-based automation systems across industrial applications.
