EL1819 - Beckhoff EtherCAT Terminal

The Beckhoff EL1819 EtherCAT Terminal provides 16 digital inputs with a nominal voltage of 24 V DC, designed to handle fast signal edges with high accuracy. Built with 1-wire connection technology, it supports both type 1 and type 3 inputs as per EN 61131-2 standards. Each channel consumes approximately 3 mA input current and features a 10 µs input filter, ensuring precise and reliable signal processing. The terminal maintains 500 V electrical isolation between the E-bus and field potential, enhancing safety. Power consumption is efficient with around 100 mA from the E-bus and 4 mA from power contacts. Its compact high-density housing measures 12 × 100 × 68 mm and weighs just 65 g, making it suitable for space-constrained panels. Designed with integrated signal LEDs, it allows real-time diagnostics and status monitoring. Certified with CE, UL, ATEX, and IECEx, the EL1819 complies with EMC, shock, and vibration standards, ensuring global industrial reliability.

The EL1819 EtherCAT Terminal is ideal for applications requiring multiple digital inputs, such as packaging machines, conveyor systems, process automation, and robotics. Engineers value its high channel density, which reduces hardware requirements while maintaining efficient performance. Its quick plug-in wiring and DIN rail installation simplify integration, while built-in LEDs enable fast diagnostics for maintenance teams. With certifications for hazardous environments, the EL1819 is trusted in industries where safety and uptime are critical. For students and junior engineers, it demonstrates how compact EtherCAT Terminals integrate high-speed communication with secure signal processing, making it a model example of scalable and future-proof automation technology.
