Each channel delivers 0–10 V signals and operates from a 24 VDC power supply, enabling consistent performance in industrial environments. The module features electrical isolation between the E-bus and signal voltage, protecting the control system from noise and ensuring signal accuracy. With optional watchdog functionality and support for distributed clocks, the EL4004 provides synchronization precision and enhanced reliability in automation systems. Key Features Four Analog Output Channels: delivers four independent 0–10 V outputs for precise voltage-based control in process and motion applications. 12-Bit Resolution: ensures fine signal granularity for accurate analog output generation across all channels. Electrical Isolation: provides 500 V isolation between the EtherCAT E-bus and signal voltage to reduce interference and improve system reliability. High-Speed Conversion: features ~250 µs conversion time for fast response in time-critical applications. Distributed Clock Support: enables sub-microsecond synchronization (“<< 1 µs”) for coordinated multi-channel output behavior. Common Ground Design: utilizes a shared ground potential across all channels to simplify wiring and integration. Robust Output Performance: supports loads > 5 kΩ, is short-circuit proof, and maintains output error below 0.1% of end value. Integrated Watchdog: optional function allows user-defined fallback values and ramp behavior in event of communication loss. The EL4004 delivers the reliability and precision required for high-accuracy analog output control in EtherCAT-based automation systems.
