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.
