Beckhoff EL19180000 EtherCAT IO Terminal Module

Beckhoff EL19180000 EtherCAT IO Terminal is an eight-channel digital input module that operates on 24 V DC and plugs directly into a Beckhoff EtherCAT network. Designed for safety applications, the EL1918 supports TwinSAFE and TwinSAFE Logic, with eight fail-safe inputs that connect to sensors with potential-free contacts. Signals are transmitted over EtherCAT via Fail-Safe over EtherCAT (FSoE) to a TwinSAFE Logic‑capable component, enabling integrated safety control within the Beckhoff safety framework. As part of the EtherCAT Terminal family, this module pairs with TwinCAT software for straightforward configuration of safety logic and I/O mapping, allowing safe sensor signals to be incorporated into automated machine safety circuits without requiring a separate safety controller. Typical uses include digital safety inputs from interlocks, safety switches, and other 24 V DC devices that must be monitored with reliable safety logic, making the EL19180000 a compact, safe-to-use option for decentralized safety input tasks in industrial automation.
