Description
Deployed for decentralized automation tasks without a control cabinet, the ER2349-0022 EtherCAT Box offers an exceptionally flexible interface for processing digital field signals. This robust module features 16 digital channels that are freely configurable as either inputs or outputs, allowing engineers to adapt the system to varying application requirements without changing physical hardware.
The ER2349-0022 operates over high-speed EtherCAT networks, establishing connection via shielded M8 screw-type sockets. Designed to withstand harsh industrial environments, the module is built with IP65, IP66, and IP67 protection ratings. It handles digital inputs conforming to EN 61131-2 Type 1/3 standards and drives digital loads (ohmic, inductive, or lamp loads) up to 0.5 A per channel. Integrated short-circuit protection and electrical isolation ensure robust operation and protect the wider control architecture.
Features
- Freely configurable digital channels: 16 independent points configured dynamically as inputs or outputs.
- Fast signal acquisition with an integrated 10 us input filter.
- Heavy-duty IP65/66/67 sealed housing designed for direct field mounting without protective enclosures.
- Reliable EtherCAT communication interface utilizing dual shielded M8 screw connectors.
- Comprehensive electrical protection, including short-circuit proof sensor supply and individual short-circuit protection on all outputs.
- Wide operating temperature range from -25 to +60 degC to handle demanding environmental conditions.
Applications
- Decentralized manufacturing lines and assembly systems.
- Material handling and conveyor automation.
- Robotic end-of-arm tooling and process cell integrations.
- Packaging, food, and beverage machinery.

Installation Guidelines
-
Mounting Position: Variable. Direct surface mounting on machinery frames is supported due to the high mechanical vibration and shock tolerance.
-
Cabling and Grounding: Ensure the EtherCAT bus lines are connected using shielded, screw-type M8 connectors. Proper grounding through the mounting surface or grounding lugs is required to ensure electromagnetic compliance.
-
Environmental Protection: To maintain IP65/66/67 ratings, protect unused sockets with appropriate sealing caps. Tighten all M8 and M12 connectors to the recommended torque specifications.
