The Beckhoff EPP6228-0022 EtherCAT P Box is a compact and versatile I/O module designed for decentralised signal acquisition and device connection in demanding automation environments. Combining eight IO-Link master channels (Class A) with eight additional digital inputs, it provides a powerful dual-function solution that reduces hardware requirements while enhancing field-level connectivity.

As an IO-Link master, the EPP6228-0022 allows the connection of up to eight IO-Link devices, such as intelligent sensors, actuators, or measuring instruments. IO-Link enables bi-directional communication, allowing not only process data to be exchanged but also diagnostic information and parameterisation. This makes the module an essential tool for implementing smart factories and Industry 4.0 strategies, where intelligent device integration and transparency are critical.

Each IO-Link port can alternatively be used as a standard digital input or output, depending on the application. The module also provides eight dedicated digital inputs via pin 2 of each M12 connection, significantly expanding its utility. These inputs operate at a nominal voltage of 24 V DC (–15%/+20%) with a typical input current of 3 mA, fully compliant with EN 61131-2 type 3 specifications. With a fast input filter of just 10 µs, the EPP6228-0022 ensures that even high-speed switching events are reliably captured without delay.

Communication is handled through the EtherCAT protocol, offering deterministic, real-time performance ideal for modern automation systems. The module supports IO-Link data transfer rates of 4.8 kbaud, 38.4 kbaud, and 230.4 kbaud, providing flexibility to connect devices with different communication requirements. The EtherCAT P interface is provided via a shielded M8 P-coded socket, combining both communication and power in a single cable, further reducing wiring complexity.

The rugged, field-ready design of the EPP6228-0022 makes it suitable for harsh industrial environments. M12 connectors provide reliable, vibration-resistant connections, ensuring dependable operation even under challenging conditions. By combining signal acquisition, communication, and power distribution in one device, the module simplifies installation and minimises the need for additional junction boxes or power feeds.

The EPP6228-0022 is particularly valuable in applications where space, flexibility, and performance are critical. It allows engineers to decentralise I/O to the field level, bringing connection points closer to sensors and actuators. This reduces wiring distances, improves clarity in system design, and supports highly modular machine architectures.

In summary, the Beckhoff EPP6228-0022 EtherCAT P Box is a highly capable and space-efficient I/O module that unites IO-Link master functionality with digital input acquisition. Offering eight Class A IO-Link channels, eight 24 V DC digital inputs, support for multiple baud rates, and robust EtherCAT P connectivity, it delivers flexibility, speed, and reliability in one compact package. Ideal for smart automation and decentralised system architectures, the EPP6228-0022 empowers users to integrate intelligent devices and digital inputs directly in the field with minimal wiring effort.
