EL1819-0000
by Beckhoff
The Beckhoff EL1819-0000 from the EL EtherCAT Terminals series by Beckhoff is a compact 16-channel digital input terminal designed for high-speed signal acquisition in industrial automation. It operates on a nominal voltage of 24 V DC with a tolerance range of -15 % to +20 %, ensuring compatibility with standard control voltages. The terminal accepts input signal voltage "1" from 11 V to 30 V, making it suitable for a broad spectrum of sensor and switch interfaces. Its primary function is to integrate discrete field signals into EtherCAT networks for real-time, deterministic control.
Featuring a typical E-bus current consumption of 100 mA and an input current of 3 mA per channel (EN 61131-2 Type 3), the EL1819-0000 balances low power draw with robust signal detection. An input filter time of 10 µs suppresses noise, while the direct plug-in technique simplifies wiring and reduces installation time. Conforming to EN 61131-2, the terminal reliably distinguishes logic levels: a “Low” signal is −3 V to +5 V and a “High” signal is 11 V to 30 V. This high channel density device integrates seamlessly into standard terminal blocks and supports variable installation positions without performance degradation.
Designed for harsh environments, the EL1819-0000 features an operating temperature range of -25 °C to +60 °C and a storage temperature range of -40 °C to +85 °C, ensuring resilience under extreme conditions. The unit’s IP20 protection rating safeguards against solid particles, and its lightweight build (approx. 65 g) reduces cabinet load. Compliance with CE, UL, and ATEX approvals confirms adherence to international safety and explosion-proof standards. In industrial applications, this terminal enhances system reliability, minimizes footprint, and accelerates commissioning, delivering efficient and precise digital input handling for automated processes.
