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.
