BECKHOFF ER2349-0021 EtherCAT Box 16-Channel Digital I/O Module

Description

Decentralized field installation without a control cabinet is streamlined with the ER2349-0021 EtherCAT Box. This robust, IP67-rated module handles up to 16 digital signals, each of which is independently configurable as either an input or an output. Operating on the high-performance EtherCAT protocol, it interfaces directly with field sensors and actuators via compact M8 screw-type connection sockets. Its versatile design is optimized for space-constrained industrial setups requiring reliable, high-density I/O routing directly in harsh environments.

Features

• 16 digital channels, freely configurable as inputs or outputs to match dynamic field requirements.
• EtherCAT high-speed fieldbus communication with integrated M8 shielded, screw-type interfaces.
• Robust housing with IP65, IP66, and IP67 protection ratings conforming to EN 60529, suitable for wet, dusty, or wet-cleaning environments.
• Individual short-circuit protection on each channel to safeguard connected sensors and actuators.
• Integrated 500 V electrical isolation between the fieldbus logic and load supply.

Applications

• Automotive manufacturing assembly lines and robotic work cells.
• Packaging, sorting, and material handling systems requiring decentralized, on-machine IP67 modules.
• Special-purpose machine building and heavy-duty process automation configurations.

Installation Guidelines

Ensure the ER2349-0021 EtherCAT Box is securely mounted to a flat surface using the integrated screw mounting holes. Tighten all M8 connection cables to their specified torque ratings to preserve the unit's IP65/66/67 physical protection barrier. Route control network cabling and high-power electrical drive lines in separate paths to minimize electromagnetic interference. Ground the bus system via the integrated earthing connection point.
