Beckhoff EL1018 8-Channel Digital Input Terminal

Beckhoff EL1018 is an eight-channel digital input terminal for EtherCAT networks that accepts 24 V DC control signals from the process level and transmits their states to a Beckhoff EtherCAT master over the EtherCAT bus. The module provides eight independent digital inputs, each with a status LED to indicate the current state, and includes a 10 µs input filter to improve noise immunity for fast-switching signals. As part of Beckhoff's EL10xx digital input family, the EL1018 is designed for DIN-rail mounting on a 35 mm rail (EN 60715) and is intended for easy stacking with other EL terminals for scalable I/O configurations. It is typically used in factory automation applications where multiple 24 VDC signals from sensors, switches, or safety interlocks must be captured quickly and reliably and fed into a Beckhoff EtherCAT master controller. The EL1018 communicates over EtherCAT, enabling low-latency, deterministic data exchange with the controller and other I/O modules, while maintaining electrical separation between the field signals and the bus for improved safety and noise rejection. This eight-channel digital input terminal is a compact, plug-and-play solution that fits seamlessly into Beckhoff automation architectures, allowing straightforward expansion of digital inputs in multi-EL10xx setups.
