BECKHOFF EP2338-0002 EtherCAT Box

Description

The EP2338-0002 is a compact, high-performance EtherCAT Box module designed for distributed industrial automation applications. This IP65/66/67-rated module features 8 digital channels, which can be configured as either digital inputs or digital outputs, providing extreme flexibility in machine control architectures. The EP2338-0002 communicates via the high-speed EtherCAT protocol and connects via robust M8 and M12 industrial-grade connectors. It is engineered for harsh environments, offering high vibration/shock resistance and a wide operating temperature range (-25 to +60 Celsius). Each output channel is individually short-circuit proof, capable of handling ohmic, inductive, or lamp loads up to 0.5 A, making it ideal for decentralized sensor and actuator integration.

Features

• 8 digital channels configurable as inputs or outputs
• EtherCAT protocol for real-time industrial communication
• IP65/66/67 protection rating for direct machine mounting
• Individually short-circuit proof output channels (0.5 A per channel)
• Integrated sensor supply from load voltage (max. 0.5 A total)
• Compact PA6 (polyamide) housing (30 mm x 126 mm x 26.5 mm)
• ATEX certified for hazardous environments (II 3 G Ex nA IIC T4 Gc)

Applications

• Distributed I/O systems in decentralized machine design
• Control of valves, contactors, and small actuators
• Sensor signal acquisition in environments requiring moisture/dust protection
• Mobile or robotics-integrated automation systems

Installation Guidelines

• Mounting: Use the two 3.5 mm diameter fixing holes to secure the module directly onto the machine frame. M3 screws are recommended.
• Connections: The EtherCAT bus interface utilizes two M8 shielded sockets. Ensure shielded cables are used to prevent interference in high-EMI environments.
• Power Supply: Connect the 24 V DC load voltage via the M8 power interface. The module provides a downstream connection M8 female socket for daisy-chaining power to subsequent EtherCAT Box modules.
• Hazardous Areas: When installed in areas rated II 3 G Ex nA IIC T4 Gc, ensure that all connections are made in a de-energized state and that cabling meets the appropriate non-incendive wiring standards.

Compliance and Certifications

• CE, UL
• ATEX: II 3 G Ex nA IIC T4 Gc
