The Beckhoff EL9505 is a compact power supply terminal designed to provide a regulated 5 V DC supply for EtherCAT Terminal systems. By converting a 24 V DC input into a precise 5 V DC output, it supports the reliable operation of low-voltage peripherals while integrating seamlessly into Beckhoff’s modular I/O platform.

The terminal delivers an output of 5 V DC ±1% with a maximum current capacity of 0.5 A. This makes it ideal for powering sensors, small electronic components, or modules that require stable low-voltage supply. By offering a dedicated 5 V DC output within the terminal row, the EL9505 eliminates the need for separate external converters, reducing wiring effort and simplifying control cabinet design.

Reliability is a core feature of the EL9505. It is fully short-circuit proof, ensuring protection against accidental wiring errors or overload conditions. An integrated diagnostic system provides clear visual feedback through an LED indicator, which signals overcurrent events. This proactive feature enables operators to quickly identify and address faults, improving system uptime and reducing maintenance time.

The input side operates from a 24 V DC supply (–15%/+20%), a standard power level in industrial automation environments. This ensures straightforward integration into existing power architectures while guaranteeing consistent and dependable operation. The regulated 5 V DC output provides clean power with minimal deviation, safeguarding the functionality of sensitive electronic devices.

The EL9505 also ensures electrical safety through 500 V isolation between the E-bus and the field potential. This isolation prevents noise or disturbances from propagating between the supply and the control system, enhancing stability in electrically demanding environments. With an E-bus current consumption of only 90 mA, the terminal is efficient and places minimal load on the system, supporting scalability for larger I/O configurations.

Compact and modular, the EL9505 integrates directly into Beckhoff’s EtherCAT Terminal system. Its slim housing saves DIN rail space while supporting neat and flexible system layouts. As part of the EtherCAT ecosystem, it can be easily combined with a wide range of I/O, communication, and power terminals, enabling tailored configurations for diverse industrial applications.

The EL9505 is particularly well suited for scenarios where stable low-voltage supply is needed within distributed control systems. Typical applications include powering 5 V sensors, signal conditioning electronics, or other auxiliary devices located in close proximity to the terminal row. By incorporating diagnostics and robust protection features, it ensures both performance and safety in daily operation.

In summary, the Beckhoff EL9505 is a reliable and compact 5 V DC power supply terminal for EtherCAT systems. Offering 0.5 A output, short-circuit protection, diagnostic LED, and 500 V isolation, it delivers the stable and safe power supply required for sensitive devices. Designed for seamless integration into Beckhoff’s modular I/O platform, the EL9505 provides efficient and dependable low-voltage power distribution in industrial automation environments.
