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.

Compliance and Certifications

Key Features:

Are the digital channels on the ER2349-0021 inputs or outputs?

The 16 digital channels on the ER2349-0021 are freely configurable, allowing each individual channel to be configured as either a digital input or a digital output.

What is the physical protection rating of the ER2349-0021?

It features an IP65/66/67 rating conforming to EN 60529, making it highly resistant to dust, water jets, and temporary immersion, suitable for direct machine mounting without a control cabinet.

What physical connector types does the module use for communication and power?

The EtherCAT bus utilizes 2 x M8 shielded screw-type sockets, the digital I/O uses M8 3-pin a-coded connections, and the power feed/downstream interfaces use 4-pin M8 sockets.
