BECKHOFF EPP1004-0061 EPP Series EtherCAT P Box

Product Overview

The EPP1004-0061 (EPP10040061) is a high-performance EtherCAT P Box from the Beckhoff EPP series, designed to simplify decentralized I/O by integrating both communication and power delivery into a single cable. Featuring 4 digital inputs in a compact, IP67-rated housing, this module is engineered for high-speed signal acquisition directly at the machine level. By utilizing the EtherCAT P protocol (power and data combined), the EPP1004-0061 significantly reduces the wiring complexity typically associated with field I/O systems, offering a streamlined, robust solution for automotive manufacturing, material handling, and modular packaging lines where rapid deployment and environmental durability are critical.

Technical Configuration

This module supports high-speed EtherCAT P communication via dual shielded M8 sockets (P-coded), which facilitates a daisy-chain topology while simultaneously powering the module and downstream devices. The inputs comply with EN 61131-2 Type 3 specifications, ensuring noise-immune signal detection across a 11–30 V range. The module is built for efficiency, consuming only 100 mA from the US supply, and provides a 0.5 A short-circuit protected supply for connected sensors. Its polyamide (PA6) construction offers excellent chemical and thermal resistance, making it suitable for rigorous industrial service.

Technical Specifications

FAQs

What is the specific advantage of EtherCAT P over standard EtherCAT?

EtherCAT P combines EtherCAT communication and 24 V DC power (US and UP) into a single standard 4-wire cable. This eliminates the need for separate power cabling to each I/O box, greatly reducing cable costs, installation labor, and cabinet footprint.

Is this module backward compatible with standard EtherCAT components?

While the EtherCAT P physical interface (P-coded M8) is distinct to prevent incorrect connections, the data protocol remains standard EtherCAT. Ensure you are using EtherCAT P-specific infrastructure components (cables and distributors) for the network segments connected to this device.

Can this box be used in environments subject to wash-down?

Yes, the EPP1004-0061 holds an IP65/66/67 rating. It is designed to withstand dust ingress and moisture exposure, including temporary immersion or high-pressure water jets, provided all M8 connections are securely seated.

Installation and Field Deployment Guidance

• P-coded Connectivity: Always ensure you use P-coded M8 connectors. Attempting to force-fit non-matching connectors can damage the contact pins and compromise the IP67 sealing integrity.
• Power Budgeting: When daisy-chaining multiple EPP modules, calculate the cumulative current load on the EtherCAT P cable. While the EPP1004-0061 is power-efficient, the main supply cable must be sized correctly to handle the total current consumption of all modules in the string plus the sensor load (0.5 A per box).
• Vibration Resistance: The 3.5 mm mounting holes are designed for M3 hardware. In high-vibration applications, utilize spring washers or thread-locking compound to ensure the mounting hardware does not loosen, as constant vibration can lead to connector wear.
