Beckhoff EJ2809 EtherCAT Plug-in Module

Description

The EJ2809 is a high-density 16-channel digital output module from the Beckhoff EtherCAT plug-in module series. Designed for integration into application-specific I/O systems, this module facilitates direct, component-level connection to backplane boards. It supports 24 V DC applications and is capable of driving ohmic, inductive, and lamp loads with a maximum current of 0.5 A per channel. The module features robust electrical isolation between the E-bus and field potential, ensuring high-speed data reliability and system safety within compact automation assemblies.

Features

• 16 digital outputs in a space-saving plug-in format
• High-speed EtherCAT communication integration
• 0.5 A per-channel output current with short-circuit protection
• Reverse voltage protection for enhanced reliability
• Compact weight (approx. 30 g) for optimized board-level design
• Wide operating temperature range: -25 degC to +60 degC

Technical Specifications

Installation Guidelines

• Integration: Designed for direct plug-in installation onto dedicated backplane boards in the EtherCAT system.
• Electrical Safety: Ensure that the 24 V DC supply remains within the specified -15% to +20% tolerance range.
• Environmental: The module is rated for -25 degC to +60 degC; ensure the final assembly provides adequate ventilation to maintain these parameters.
• Operational Limits: Each channel is individually short-circuit proof; however, verify that total current load remains within system backplane specifications.
• Compliance: Ensure the application meets EN 61000-6-2/6-4 standards for EMC immunity and emission during system design.
