Beckhoff ER1018-0002 EtherCAT Box Digital Input Module

Description

Acquiring binary control signals directly from the field level, the ER1018-0002 EtherCAT Box offers a robust, decentralized I/O solution for demanding industrial environments. This module features eight digital inputs with a fast 10 us input filter, making it ideal for capturing high-speed sensor states without the need for a protective control cabinet. By processing signals locally and communicating via high-performance EtherCAT, the module minimizes wiring complexity and reduces signal latency across distributed automation architectures.

Housed in a rugged, zinc die-cast enclosure, the ER1018-0002 provides exceptional mechanical stability and resistance to environmental factors. It features M12 input connections and M8 EtherCAT interfaces, ensuring secure, vibration-resistant connections. The integrated sensor supply is short-circuit proof and derived directly from the control voltage, protecting connected field devices and maintaining system uptime in harsh operating conditions.

Features

• Eight digital inputs designed for 24 V DC signals (Type 1/3 specifications).
• Fast 10 us input filter for reliable signal processing and minimal propagation delay.
• Robust zinc die-cast housing providing IP65, IP66, and IP67 protection ratings.
• Direct connection of 2-wire and 3-wire sensors via M12 x 1, 5-pin, a-coded sockets.
• Short-circuit proof sensor supply up to 0.5 A total.
• Complete electrical isolation between the control voltage and the fieldbus network.
• EtherCAT communication interface via shielded, screw-type M8 connections.

Applications

• Automotive manufacturing and robotic assembly lines.
• Material handling, sorting systems, and conveyor networks.
• Machine tool construction and heavy machinery control.
• Food processing and packaging plants requiring washdown-compatible IP67 hardware.
• Water and wastewater treatment facilities with decentralized instrumentation.

Installation Guidelines

• Mounting: Secure the module directly to the machine frame or mounting plate using the 2 integrated fixing holes (3.5 mm diameter, designed for M3 screws).
• Grounding: Ensure a low-impedance connection between the zinc die-cast housing and the machine ground to optimize EMC shielding and noise immunity.
• Cabling: Use shielded M8 cabling for EtherCAT communication. Tighten all M8 and M12 connectors to the specified torque to maintain the IP67 environmental seal.
• Power Distribution: When daisy-chaining multiple EtherCAT Box modules, verify that the total current draw does not exceed the maximum rating of the M8 power connectors.
