BECKHOFF EL4114 EtherCAT Terminal

Description

Designed for highly precise industrial signal processing, the BECKHOFF EL4114 analog output terminal generates analog control currents in the 0 to 20 mA range. This 4-channel output module features a high 16-bit resolution, delivering accurate control variables directly to field devices such as proportional valves, variable speed drives, and process indicators. Integrating natively into the EtherCAT high-speed communication network, the terminal supports Distributed Clocks (DC) to achieve synchronization precision of less than 1 microsecond, making it ideal for highly synchronized multi-axis control loops and demanding automation processes.

The compact 12 mm housing includes diagnostic LEDs indicating active status and communication states. The EL4114 utilizes 2-wire, single-ended connection technology, allowing for clean, space-saving cabinet layouts. Integrated parameterizable watchdog timers ensure safe fall-back states in the event of a control bus interruption.

Features

• Four analog output channels processing standard 0 to 20 mA signals.
• High-resolution 16-bit digital-to-analog conversion for fine control increments.
• EtherCAT Distributed Clocks (DC) support with precision under 1 µs.
• 2-wire, single-ended wiring configuration.
• Short-circuit proof outputs with a maximum load capacity of 350 ohms.
• Configurable watchdog parameters for safety during communication faults.
• Robust electrical isolation of 500 V between the internal E-bus and signal channels.

Applications

• Proportional valve control and actuator positioning.
• Speed referencing for variable frequency drives (VFDs) and motor controllers.
• Analog signal transmission to remote recorders or data acquisition units.
• Process loop control in oil & gas, water treatment, and power generation.

Technical Specifications

Connections and Interfaces

Note: Stripping length for terminals is 8 to 9 mm. Wire release via spring-actuated mechanism using a standard screwdriver.

Installation Guidelines

• Mount vertically on standard 35 mm DIN rails conforming to EN 60715 using the integrated locking mechanism.
• Ensure secure side-by-side connection using the built-in double slot and key system on the terminal housing.
• An IP20 rated enclosure must be utilized to safeguard against environmental contaminants and conductive dust.
• Avoid routing sensitive analog signal lines parallel to high-voltage power cables to minimize EMI coupling.
