Description  The Beckhoff EL9400 is an EtherCAT power supply terminal that provides 5 V DC, 2 A power to refresh the E-bus within EtherCAT systems. It ensures stable data exchange between EtherCAT couplers and terminals, making it ideal for configurations with large numbers of modules requiring additional E-bus current.     Technical Specifications  Condition New/Never Used Surplus Brand Beckhoff Category Industrial Automation Part Number EL9400 Subcategory Power Supply Terminal Technology Power supply terminal for E-bus Input Voltage 24 V DC (-15% / +20%) Input Current Typ. 70 mA + (E-bus current/4) Output Voltage 5 V DC for E-bus Output Current 2 A Electrical Isolation 500 V (E-bus/field potential) Power Contacts Max. 24 V DC / 10 A E-bus Function Supplies and refreshes E-bus power for data communication Configuration Not required Mounting Type DIN-rail via EtherCAT Terminal system Protection Class IP20 Operating Temperature 0°C to +55°C Storage Temperature -25°C to +85°C Relative Humidity 95%, non-condensing Weight Approx. 65 g   Information About EL9400 The EL9400 is part of Beckhoff’s EtherCAT Terminal system and serves as a dedicated power supply terminal for maintaining reliable E-bus operation. In EtherCAT installations, each terminal draws a certain amount of current from the E-bus. For larger configurations or systems with high power demands, the EL9400 adds an additional 2 A of E-bus power to ensure consistent communication and stability across all connected modules. This terminal also allows up to 10 A at 24 V DC for the power contacts, extending flexibility for peripheral devices. Its 500 V isolation between the E-bus and field potential enhances operational safety, while the compact form factor simplifies integration into existing EtherCAT systems. Key Features: E-bus Power Refresh: Supplies an additional 2 A at 5 V DC to maintain consistent E-bus voltage and communication reliability. Supports Large Configurations: Ideal for EtherCAT systems with many terminals requiring higher E-bus current capacity. Stable Power Distribution: Ensures uninterrupted data exchange between EtherCAT couplers and terminals. High Electrical Isolation: Provides 500 V isolation between E-bus and field potential for secure operation. Auxiliary Power Contacts: Offers 24 V DC power distribution up to 10 A for connected components. Plug-and-Play Integration: Automatically recognized within EtherCAT networks, requiring no configuration. Compact Design: EtherCAT Terminal housing allows quick DIN-rail mounting alongside standard modules. Industrial-Grade Reliability: Operates within 0°C to +55°C and up to 95% humidity for robust field performance. The EL9400 delivers the reliability and precision required to maintain stable E-bus power and communication integrity in complex EtherCAT automation systems.
