The Beckhoff EL1114 is a 4-channel digital input EtherCAT Terminal that delivers fast and reliable acquisition of 24 V DC signals in industrial and building automation systems. With support for both 2-wire and 3-wire connection technology, compliance with international standards, and a rapid 10 µs input filter, the EL1114 provides dependable performance for real-time applications.

Designed for flexibility, the terminal can capture up to four independent input signals, making it suitable for connecting sensors, switches, and other digital devices. Operating at a nominal voltage of 24 V DC (with a tolerance of –15% to +20%), it aligns with common industry standards, ensuring straightforward integration into existing power and signal infrastructures. Each input requires a typical current of 3 mA, compliant with EN 61131-2, type 3, to guarantee reliable activation of industrial sensors while maintaining efficiency.

Speed is a standout feature of the EL1114. With a typical input filter time of only 10 µs, the terminal ensures rapid detection of state changes. This makes it particularly valuable in applications where timing precision is critical, such as monitoring high-speed processes, capturing encoder signals, or managing interlocks in machine automation. By enabling real-time responsiveness, the EL1114 enhances the accuracy and performance of automation systems.

The terminal also supports both 2-wire and 3-wire connection methods, offering greater flexibility in wiring and simplifying system design. This versatility makes it adaptable to a wide range of installation scenarios, from simple signal capture to more complex control schemes where ground or reference connections are required.

The EL1114 is compact and efficient in operation. Its slim housing helps conserve DIN rail space, supporting high-density cabinet layouts. With a typical power contact consumption of just 2 mA plus the connected load, it places minimal demand on the system, ensuring scalability for larger I/O configurations without significant increases in power requirements.

Seamless integration into Beckhoff’s EtherCAT platform allows the EL1114 to transmit data deterministically to the controller, ensuring precise coordination with other system components. Like other EtherCAT Terminals, it requires no additional configuration, simplifying commissioning and reducing setup time.

In practical use, the EL1114 is ideal for acquiring signals from sensors, limit switches, and operator inputs in machinery. It is equally effective in process automation for capturing fast digital events, or in building automation for managing low-latency signals such as alarms, door contacts, or lighting controls. Its combination of speed, standards compliance, and compact design makes it a versatile solution across industries.

In summary, the Beckhoff EL1114 is a reliable 4-channel digital input terminal tailored for 24 V DC applications. With a 10 µs input filter, 2-/3-wire connection technology, compliance with EN 61131-2 standards, and efficient power usage, it offers precise, high-speed signal acquisition for modern automation environments.
