Beckhoff EPP2328-0001 EtherCAT P Box

Product Overview

The Beckhoff EPP2328-0001 is a high-performance, ruggedized digital I/O module from the EtherCAT P Box series. Featuring 4 digital inputs and 4 digital outputs, this module is specifically designed for EtherCAT P (Power over EtherCAT) environments. By combining communication and 24 V DC power onto a single cable, the EPP2328-0001 significantly reduces wiring complexity and installation time. Housed in an IP65/66/67-rated enclosure, it is purpose-built for decentralized automation in harsh, industrial, or washdown environments where space-saving and robust performance are critical.

Technical Configuration

The EPP2328-0001 leverages the efficiency of EtherCAT P to provide high-speed data and power distribution.

• EtherCAT P Integration: The P-coded M8 bus interface carries both the EtherCAT signal and the system/sensor supply voltage, eliminating the need for separate power cabling to each box.
• High-Current Handling: Capable of switching up to 2 A per channel, making it well-suited for controlling larger actuators, solenoids, or lamp loads that exceed the capacity of standard I/O modules.
• Rugged Design: The IP65/66/67 rating ensures total protection against dust and water immersion, ideal for direct machine mounting in manufacturing plants.
• Diagnostic Capabilities: Integrated short-circuit protection for each channel provides real-time feedback to the controller, allowing for rapid identification of load-side electrical faults.

Frequently Asked Questions

What is the advantage of using EtherCAT P (EPP) over standard EtherCAT (EP)?

The primary advantage is wiring reduction. Standard EtherCAT requires a separate power cable for the 24 V sensor/load supply. EtherCAT P uses a specially coded M8 connector to transmit both the data and the 24 V power over the same cable, which simplifies machine build and reduces the number of required cable runs.

Is there a limit to the current I can draw through the EPP2328-0001?

While each individual output can handle up to 2 A, there is a total summation limit of 3 A for the outputs combined. You must ensure that the total load demand of your connected actuators does not exceed this total current limit to prevent thermal damage to the module.

Can I connect this to a non-EtherCAT P port?

No. EtherCAT P hardware uses specialized P-coded connectors that are mechanically incompatible with standard EtherCAT (RJ45 or standard M8) ports. This design prevents the accidental connection of high-voltage power lines into standard data ports.

Engineering Integration and Operational Best Practices

• Cable Management: Use official Beckhoff EtherCAT P cables to ensure proper power delivery and data integrity. Because the cable carries both power and data, ensure you are not exceeding the voltage drop limits for your cable length.
• Total Load Monitoring: Because the total output current is capped at 3 A, calculate your expected peak load for all 4 outputs simultaneously. If your process requires more than 3 A at any one time, you will need to distribute your loads across additional I/O modules.
• Seal Integrity: In IP67-rated environments, ensure that all unused M8 ports are fitted with protective caps. Failure to seal unused ports is the most common cause of premature failure in washdown environments.
• Mounting: Utilize the provided mounting points to attach the module to a grounded machine surface. Proper grounding helps maintain the integrity of the shielded bus interface and ensures compliance with EMC emission standards.
