Beckhoff EPP2318-0001 EtherCAT P Box

Product Overview

The EPP2318-0001 (EPP2318-0001) is a high-performance, decentralized I/O module from the EtherCAT P Box series, integrating 4 digital inputs and 4 digital outputs in a rugged, IP67-rated enclosure. By utilizing the EtherCAT P protocol, this module combines high-speed communication and power distribution (US and UP) into a single M8 P-coded cable, significantly reducing wiring complexity at the machine level. Its ground-breaking design allows for direct installation on machine frames, making it an ideal choice for high-speed, decentralized automation tasks in harsh environments such as food processing, automotive assembly, and material handling systems where wash-down resistance and durability are mandatory.

Technical Configuration

The EPP2318-0001 features an advanced hardware architecture optimized for rapid signal processing, with input filters of 10 µs and output switching times of 50 µs (TON) / 100 µs (TOFF). The module supports 24 V DC operation and provides individually protected outputs (0.5 A) capable of driving ohmic, inductive, and lamp loads. With a total sensor supply capacity of 0.5 A (short-circuit proof), it reliably powers field devices while maintaining diagnostic monitoring through the EtherCAT master. The compact, polyamide housing is designed for versatile installation, utilizing A-coded M8 connectors for I/O signals to ensure compatibility with standard industrial sensors and actuators.

Technical Specifications

FAQs

What is the benefit of using EtherCAT P for this module?

EtherCAT P integrates power and data into one cable, eliminating the need for separate power distribution lines for each module. This dramatically simplifies machine design, reduces cable length, and speeds up assembly time.

Can this module be mounted in wet or dusty locations?

Yes. The EPP2318-0001 is fully rated for IP65/66/67, meaning it is protected against dust and water jets/temporary immersion, making it suitable for almost any industrial production environment.

How are short-circuits handled at the output channels?

Each output channel is equipped with current limiting (typ. 1.5 A) and short-circuit protection. If a fault is detected, the module safely disables the specific channel and reports the error to the EtherCAT master for rapid diagnostics.

Is the sensor supply power sourced from the EtherCAT P cable?

Yes. The sensor power is derived directly from the EtherCAT P feed-in voltage (UP), streamlining your machine's power distribution by eliminating the need for additional sensor power cables.

Installation Guidelines and Best Practices

• P-coded Connectivity: Always ensure that you are using genuine P-coded M8 cables for the EtherCAT P bus. The P-coding is specifically designed to prevent accidental connection to standard Ethernet ports, protecting your hardware from electrical damage.

• Vibration Mounting: Given the decentralized nature of the module, ensure it is mounted to a rigid part of the machine frame. Use high-quality M3 bolts to secure the box, and periodically check the tightness of the M8 connectors to ensure the IP67 seal is maintained.

• Daisy-Chaining Limits: While EtherCAT P allows for daisy-chaining, be mindful of the voltage drop over long cable runs. Monitor your system power budget closely when adding multiple EPP modules to a single EtherCAT P segment to ensure voltage levels at the end of the line remain within the specified range.
