BECKHOFF ELX9410 Power Supply Terminal for E-bus Refresh

Description

The ELX9410 is a specialized power supply terminal engineered for E-bus refresh in Beckhoff ELX and EL series terminal systems. This module provides a regulated 5 V DC supply to the E-bus, ensuring stable power delivery in terminal configurations where the primary supply may be insufficient due to high load or long terminal strings. The ELX9410 is designed for hazardous environments, featuring comprehensive ATEX, IECEx, and cFMus certifications for use in potentially explosive atmospheres (Zone 2/Division 2). It includes integrated diagnostics in the process image, allowing controllers to monitor terminal power status in real-time. The unit is fully short-circuit proof and maintains high reliability within a compact 12 mm housing width.

Features

• E-bus refresh functionality for ELX and EL terminal series
• 5 V DC output for stable E-bus supply (up to 1 A)
• Integrated diagnostic feedback via process image
• Short-circuit proof design for enhanced safety
• Compact 12 mm housing
• Wide operating temperature range: -25 to +60 Celsius
• Suitable for hazardous areas (ATEX, IECEx, cFMus rated)

Applications

• Powering extensive EtherCAT I/O segments in hazardous locations
• Maintaining E-bus voltage levels in complex control systems
• Industrial automation requiring robust, certified power distribution
• Decentralized I/O nodes in oil, gas, or chemical process environments

Installation Guidelines

• Mounting: Snap the ELX9410 onto the DIN rail as part of your EtherCAT terminal segment.
• Placement: Position the module at points in the terminal string where E-bus power consumption approaches the specified limits of the coupler or previous power supply.
• Diagnostics: Configure the host controller to read the diagnostic bits from the process image to receive immediate notification of voltage drops or short-circuit events.
• Hazardous Area Precautions: Ensure all installation practices conform to local safety standards for Class I, Division 2 or Zone 2 environments (e.g., proper sealing and non-incendive wiring practices).
