The Beckhoff EPP1332-0001 EtherCAT P Box is a decentralised I/O device designed to extend and refresh EtherCAT P networks in the field. Serving as a 2-port junction with integrated refresh for both US (system voltage) and UP (peripheral voltage), it provides engineers with a compact and reliable solution for distributing both communication and power across modular machine architectures.

At its core, the EPP1332-0001 features one EtherCAT P input and three EtherCAT P outputs, creating a convenient branching point within EtherCAT P topologies. This enables flexible wiring layouts, allowing machine builders to design systems with star, tree, or hybrid structures without requiring additional switches or distribution units. By refreshing the US and UP supply, the module ensures that stable power and communication signals are delivered downstream, even in extended network segments.

The device is designed to handle a nominal 24 V DC supply (-15%/+20%), with a total current capacity of up to 3 A for both US and UP across all connected ports. This makes it suitable for powering distributed I/O modules, sensors, and actuators, while maintaining reliable EtherCAT communication. The module itself consumes only ~100 mA from US, ensuring efficient operation and leaving more available power for connected devices.

Connectivity is provided via robust M8 P-coded shielded sockets, which are widely used in industrial environments for their compact size and secure connections. These connectors ensure high resistance to vibration, dust, and moisture, making the EPP1332-0001 well suited for direct installation in the field, close to machinery and devices.

As part of the EtherCAT P family, the EPP1332-0001 combines the advantages of EtherCAT’s high-speed, deterministic communication with integrated power transmission for both the control electronics (US) and connected peripherals (UP). This reduces wiring complexity, as a single cable carries both data and power, lowering installation costs and simplifying machine layouts. The module’s refresh function ensures that voltage quality and stability are maintained, even when multiple devices are daisy-chained or when long cable runs are used.

Typical applications for the EPP1332-0001 include modular machine construction, robotics, packaging equipment, and distributed control systems, where decentralised power and communication distribution are essential. Its ability to serve as a compact junction point with power refresh functionality makes it a valuable component in designing scalable, reliable, and cost-efficient EtherCAT P networks.

In summary, the Beckhoff EPP1332-0001 EtherCAT P Box is a compact and powerful junction module that enhances EtherCAT P topologies with branching and power refresh capabilities. With one input, three outputs, robust M8 connectors, and efficient 24 V DC power handling, it delivers flexibility, reliability, and performance for modern decentralised automation systems.
