BECKHOFF EL9227-6600 EtherCAT Terminal

The EL9227-6600 is a 2-channel overcurrent protection terminal engineered by BECKHOFF for 24 V DC systems. This advanced EtherCAT Terminal provides precise, adjustable electronic fuse protection ranging from 1 A to 4 A, helping to safeguard sensitive industrial components from overcurrent conditions. The module features integrated fail-safe elements, reverse polarity protection, and extended diagnostic functionalities, including adjustable advance warnings for load and low-voltage thresholds.

Features

• 2-channel electronic overcurrent protection for 24 V DC circuits
• Adjustable rated current: 1 A to 4 A in 1 A steps
• Integrated 6 A (T) fail-safe element
• Diagnostic features: adjustable advance warning for load (50–100%) and low-voltage (17–24 V DC)
• Reverse polarity and over-voltage (≥ 32 V DC) protection
• Output 1 accessible via power contact
• LED interface with integrated button for status and control
• Compact 12 mm wide housing for DIN rail mounting

Applications

• Protection of 24 V DC distribution circuits in machines
• Monitoring and safeguarding of sensors and actuators
• Industrial control panels requiring granular current limiting
• Distributed power supply protection in automation systems

Technical Specifications

Installation Guidelines

• Mount the module onto a 35 mm DIN rail (EN 60715) and lock it into place.
• Use the double slot and key connection for reliable side-by-side assembly with other terminals.
• Wire inputs and outputs using the spring-actuated terminals; supports solid (0.08–2.5 mm2) and flexible (0.14–1.5 mm2) conductors.
• Observe the 8–9 mm stripping length for optimal contact.
• Ensure adequate airflow for heat dissipation to maintain ambient temperatures within 0 to +55 degC.
• Utilize BZxxx series labels for clear identification of terminal channels.
