Description

The BECKHOFF ER2328-0002 is a high-performance, decentralized EtherCAT Box module housed in a robust zinc die-cast enclosure. Designed for mounting directly on machinery outside of a traditional control cabinet, this IP67-rated module combines four digital inputs and four digital outputs in a single field-level unit. It provides reliable and space-saving sensor data acquisition and actuator control in harsh industrial environments.

For communication, the ER2328-0002 utilizes two shielded M8 screw-type sockets to integrate seamlessly into an EtherCAT network. The four digital inputs are built to EN 61131-2 Type 1/3 specifications and feature a 3.0 ms input filter. The four digital outputs are capable of switching loads up to 2.0 A, making this module well-suited for driving solenoid valves, contactors, indicators, and other high-current actuator components directly in the field.

Features

• Robust zinc die-cast housing designed for direct machine mounting in demanding environments.
• Four digital inputs (24 V DC) with a 3.0 ms input filter, conforming to EN 61131-2 Type 1/3.
• Four high-capacity digital outputs supporting up to 2.0 A per channel.
• Dual M8 shielded screw-type interfaces for secure EtherCAT bus communication.
• M12 x 1, 5-pin, A-coded connection technology for reliable I/O integration.
• Integrated short-circuit-proof sensor supply derived from the control voltage.
• High-level protection rating of IP65/66/67 for resistance against dust, moisture, and liquid ingress.

Applications

• Decentralized field-level installation on machinery with limited enclosure space.
• Direct control of high-current actuators, including contactors, lamps, and hydraulic or pneumatic valves.
• Sensor and actuator processing in conveyor systems, packaging machines, and assembly lines.
• Industrial automation environments requiring robust IP67-rated network interfaces.

Installation Guidelines

1. Ensure all power sources feeding the machine and local supply segments are fully de-energized before mounting.
2. Position and secure the ER2328-0002 box onto the machine framework using the integrated mounting holes on the metal housing. Ensure the mounting position provides stable mechanical alignment.
3. Connect the incoming and downstream EtherCAT network lines using shielded, screw-type M8 cabling. Tighten the connectors to the recommended torque to maintain IP65/66/67 integrity.
4. Connect the 24 V DC auxiliary and control power supplies to the M8 feed socket, and daisy-chain to downstream modules via the M8 female socket if required.
5. Securely wire the digital field sensors and actuators to the A-coded M12 sockets.
6. Perform a final physical inspection of all connection points and ensure unused ports are protected with compatible sealing caps before applying system power.

Replacement Recommendations

When replacing an active ER2328-0002, always turn off the control power (Us) and peripheral load power (Up). Label and document all M8 and M12 field connections before unplugging them to prevent configuration errors. Once the hardware swap is complete and the cable connectors are tightened to preserve IP protection, the EtherCAT master will automatically detect and integrate the replacement module during initial boot-up.
