The Beckhoff EtherCAT Terminal EL1098 is equipped with 8 digital inputs based on 1-wire ground-switching technology, operating at a nominal 24 V DC. It supports signal thresholds of 18–30 V DC for “0” and 0–7 V DC for “1”, with a typical 3 mA input current. A 10 µs input filter ensures fast and accurate response, while 500 V isolation between the E-bus and field potential provides system safety. The module consumes around 90 mA via the E-bus and 25 mA from power contacts, ensuring efficient operation. Its compact polycarbonate housing, IP20 protection, and certifications such as CE, UL, ATEX, IECEx, DNV GL, and CCC make the EL1098 EtherCAT Terminal a robust choice for demanding automation environments.
The Beckhoff EL1098 EtherCAT Terminal is widely used in machine automation, conveyor systems, material handling, and packaging lines. Its ability to handle fast 24 V DC signals makes it ideal for integrating push buttons, limit switches, and sensors. Maintenance engineers benefit from the spring-actuated wiring and compact DIN rail mounting, while system integrators value its seamless EtherCAT compatibility for synchronized input capture across distributed systems. The module’s design also simplifies diagnostics with integrated signal LEDs, enabling faster troubleshooting and reduced downtime.
Combining performance, durability, and compliance, the Beckhoff EtherCAT Terminal EL1098 is trusted across industries such as automotive, electronics, logistics, and process automation.
