Beckhoff EP1098-0001 EtherCAT Box

Product Overview

The EP1098-0001 (EP1098-0001) is an 8-channel digital input module from the Beckhoff EtherCAT Box series, designed for rugged, machine-level applications. This module features a high degree of protection (IP65/66/67), making it ideal for decentralized installation directly on machinery or in harsh industrial environments where exposure to dust, moisture, and vibration is common. The EP1098-0001 utilizes ground-switching logic and provides high-speed signal processing with a 10 µs input filter, ensuring rapid and accurate data acquisition for demanding motion and control tasks.

Technical Configuration

The EP1098-0001 is built for durability and ease of integration into field-level automation. It features M8 connectivity for both the EtherCAT bus interface and the input channels, facilitating a clean, plug-and-play wiring installation. The module supports a 24 V DC supply, with internal sensor power distribution protected by a short-circuit-proof 0.5 A output. The compact polyamide (PA6) housing is designed for direct mounting to machine frames using M3-sized fixing holes. Its fieldbus interface includes dual M8 sockets, supporting standard daisy-chain configurations that eliminate the need for extra network switches or complex branching at the machine level.

Technical Specifications

FAQs

What is the advantage of 'ground switching' input logic?

Ground switching (also known as negative switching) logic is often required in specific regional or legacy automation architectures where the sensor signal connects to the common ground rather than the positive supply voltage. Ensure your sensors are compatible with this switching topology.

Can this module be mounted in areas subject to wash-down procedures?

Yes. Due to its IP65/66/67 protection rating, the EP1098-0001 is designed to withstand exposure to water jets and dust, making it suitable for wash-down applications in food processing or manufacturing equipment.

Are the M8 sockets standard?

Yes, the module uses standard A-coded M8 connectors for input channels and communication, which are widely available and ensure a reliable, vibration-resistant connection in high-motion environments.

How is the power supply managed in a daisy-chain configuration?

The module includes both a male feed socket and a female downstream socket for power, allowing for easy loop-through of the 24 V DC control voltage across multiple EtherCAT Boxes without requiring individual home-run power cables for every module.

Installation Guidelines and Best Practices

• Mounting: Use the two 3.5 mm fixing holes with M3 bolts to mount the module securely to a flat, rigid surface. Ensure the mounting point is free from high-frequency vibration sources to prevent mechanical fatigue of the housing over time.

• Cabling: Use shielded EtherCAT patch cables to connect the modules. Given the M8 connectivity, ensure all plugs are hand-tightened to maintain the IP67 seal and prevent communication errors caused by moisture ingress or loose contacts.

• Sensor Power: The internal sensor supply is limited to 0.5 A total. When connecting multiple sensors, verify that the combined current draw does not exceed this limit; if higher currents are required, use a separate power distribution terminal or box.
