Product Overview

The Beckhoff EPP1321-0060 is a 1-channel EtherCAT to EtherCAT P supply module. This device converts standard EtherCAT to EtherCAT P protocol within an IP67-rated enclosure.

The module enables flexible conversion for distributed machine applications. Furthermore, it features status LEDs for indicating EtherCAT, US, and UP. Therefore, it suits harsh industrial environments requiring ruggedized communication.

Key Features

The EPP1321-0060 offers several advantages for EtherCAT P networks.

Protocol Conversion:
Converts standard EtherCAT to EtherCAT P. Therefore, it enables the use of EtherCAT P devices on existing EtherCAT networks.

IP67 Rugged Housing:
Rated IP65/66/67 for harsh environments. Consequently, it can be mounted directly on machines without an additional enclosure.

High Current Capacity:
Supplies 3A per US and UP. Hence, it powers many sensors and actuators on one segment.

M8 Connectors:
Uses industry-standard M8 connectors for power and bus. For this reason, cabling is simplified and readily available.

Status LEDs:
Indicates EtherCAT, US, and UP status at a glance. Thus, troubleshooting is faster.

Wide Temperature Range:
Operates from -25°C to +60°C. Therefore, it suits cold and moderately hot industrial environments.

Scalable Architecture:
Supports power supply boost and branching via EPP1332-0001 and EPP1342-0001. Consequently, large or complex machines can be accommodated.

Lightweight Design:
Weighs only 90g. Hence, it adds minimal load to cable assemblies.

Typical Applications

The EPP1321-0060 suits various distributed EtherCAT P applications.

• Converting standard EtherCAT to EtherCAT P for field devices.

• Powering sensors and actuators in IP67-rated environments.

• Distributed machine control systems requiring rugged I/O.

• Retrofit upgrades to existing EtherCAT networks.

• Applications requiring 3A per US and UP current capacity.

Installation Guidelines

Install the EPP1321-0060 in a variable position due to its IP67 rating. First, connect the EtherCAT input via the M8 bus interface (shielded, screw type, EtherCAT-P-coded). Then, connect the EtherCAT P output to downstream devices.

Connect the US and UP voltages via the 4-pin M8 plug connector. The voltage can optionally be forwarded to downstream devices. The total current feed-in is 3A maximum per US and UP.

For larger systems requiring power boost, use the EPP1332-0001 junction. For branches without voltage refresh, use the EPP1342-0001. All connections use M8 connectors.
