It provides eight individually switchable outputs capable of handling various load types, including ohmic, inductive, and lamp loads. Using Beckhoff’s XFC (eXtreme Fast Control) technology, the EL2258 achieves precise timing with distributed clocks and multi-timestamping functionality. This allows multiple time-stamped events to be processed per EtherCAT cycle, ensuring deterministic signal switching. The module also supports automatic activation for repetitive switching tasks, making it ideal for advanced motion control, signal simulation, and precise process synchronization applications. Key Features: Eight Digital Outputs: Offers 8 channels with 24 V DC, 0.5 A capability for versatile signal control in industrial automation. High-Speed Switching: Achieves typical TON and TOFF times under 1 µs for rapid signal response. Multi-Timestamp Functionality: Enables storage and execution of multiple time-stamped switching events per EtherCAT cycle. Distributed Clock Synchronization: Utilizes EtherCAT distributed clocks with precision better than 1 µs for synchronized operation. Auto-Activation Feature: Supports automated output control sequences for consecutive switching tasks in each bus cycle. Wide Load Compatibility: Suitable for ohmic, inductive, and lamp loads with built-in protection against short circuits and reverse voltage. Advanced Safety and Isolation: Provides 500 V electrical isolation between E-bus and field potential for secure system operation. Compact and Efficient Design: IP20-rated housing allows DIN-rail installation and efficient integration in distributed control systems. The EL2258 delivers the reliability and precision required for motion synchronization, fast digital control, and time-critical automation processes.
