Product Description:

The EL1098 EtherCAT Terminal represents a small eight-channel digital input module developed by Beckhoff Automation. The device functions to deliver fast signal acquisition with reliable performance. The module operates within EtherCAT networks by providing accurate input reading for automation systems.

The EL1098 EtherCAT Terminal functions at 24 V DC nominal voltage with -15% to +20% tolerance. The device detects ground-switching inputs using 1-wire connection technology. The terminal indicates a "0" signal through a voltage range from 18 V to 30 V DC and detects a "1" signal when the voltage falls between 0 V and 7 V DC. The input terminals consume 3 mA during normal operation. The module provides a quick input filtering process of 10 µs to deliver fast signal processing through a 10 µs input delay. The power contacts supply 25 mA of power while the EtherCAT E-bus provides around 90 mA of power. The EL1098 EtherCAT Terminal operates effectively within a temperature range of 0°C to 55°C while it can be safely stored between -25°C and +85°C. The terminal meets IP20 protection standards which indicate its suitability for control cabinet use per manufacturer guidelines. The device receives international application authorization through CE, CCC, UL, ATEX, IECEx and DNV GL certifications.

The EL1098 EtherCAT Terminal delivers optimal performance in precise machine control systems. The small size of this product helps maximize available control panel space. This terminal detects fast input changes in critical processes with its quick response time. The integration with EtherCAT system enables real-time synchronized data communication among machines. The terminal holds multiple international certifications which enable it to fulfill worldwide industrial safety and performance standards. This device provides dependable operation with swift signal processing abilities that make it the perfect solution for contemporary industrial automation systems.
