Eth power distribution box

EtherCAT power distribution boxes manage and protect multiple 24 V DC power branches in industrial automation systems, offering monitoring, overcurrent protection, and modular connectivity.

Overview

EtherCAT power distribution boxes are specialized modules designed to distribute and manage power for EtherCAT-connected devices in industrial automation. They allow multiple outputs to be supplied from a single input while providing overcurrent protection, monitoring, and diagnostic capabilities. These boxes are essential for ensuring reliable operation of control systems, servo drives, sensors, and other peripherals in networked environments.

Key Features

EP9224-0023 EtherCAT Box:

• Connects four 24 V power supply branches with independent monitoring of control voltage (U_S) and peripheral voltage (U_P) for each branch.
• Electronic overcurrent protection automatically switches off affected outputs in case of short circuits, while keeping other branches active.
• Input voltage is maintained above 21 V during faults or startup, allowing high-capacity consumers to be added without issues.
• Diagnostic data, including current and voltage values, can be read via the EtherCAT interface, enabling precise error localization.
• Supports cascading multiple modules for expanded power distribution.
• Class 2 approval according to UL1310 allows safe implementation of circuits under 100 VA with standard power supplies (Beckhoff EP9224-0023) . EP9208-1035 EtherCAT Box:
• A fully passive distribution box with eight M12 L-coded outputs, suitable for 24 V DC or 48 V DC applications.
• Each output can carry up to 16 A, with LEDs indicating channel status.
• No intermediate electronics; power is directly routed to connected devices, ideal for smart servo drives or simple distribution needs .

Applications

• Industrial automation and control systems
• Networked servo drives and sensors
• Modular machine setups requiring selective load protection
• Telecommunications and data center power distribution (via Power-D-Box systems)

Advantages

• Selective load disconnection prevents downtime by isolating only the faulty branch.
• Modular design allows easy expansion and retrofitting without interrupting the entire system.
• Diagnostic capabilities provide real-time monitoring and historical data logging for maintenance and troubleshooting.
• Compact and flexible installation in 19" or ETSI racks, suitable for space-constrained environments. EtherCAT power distribution boxes, such as the EP9224-0023 and EP9208-1035, provide a reliable, modular, and safe solution for distributing power in complex industrial networks, combining protection, monitoring, and flexibility for modern automation systems.
