BECKHOFF EL4114-0020 EtherCAT Terminal

Description

The BECKHOFF EL4114-0020 is a high-precision, 4-channel analog output EtherCAT Terminal designed for generating accurate current signals within industrial control systems. Operating in the range of 0 to 20 mA, this specialized terminal features 16-bit resolution and comes factory calibrated to ensure exceptional signal fidelity and minimal output error.

Compared to standard analog output models, the BECKHOFF EL4114-0020 variant is optimized for demanding automation and testing environments where high-precision control loop feedback is mandatory. Its integration into the EtherCAT system allows for fast, deterministic signal transmission, making it a reliable component in multi-axis machinery and distributed process systems.

With built-in support for Distributed Clocks (DC), the terminal enables synchronized output actions across the entire network with sub-microsecond precision. The 2-wire connection layout allows for a clean, space-saving arrangement within standard terminal boxes and electrical enclosures.

Features

• 4 analog output channels delivering current signals from 0 to 20 mA
• Enhanced 16-bit signal resolution for high-accuracy setpoint adjustment
• Factory calibrated with an individual calibration certificate included
• Distributed Clocks (DC) compatibility for highly synchronized output updates
• Short-circuit proof current outputs supporting loads up to 350 Ohms
• Parameterizable watchdog function to handle communication interruptions safely
• Compact 12 mm terminal housing with integrated status LEDs

Applications

• High-precision control valve and actuator positioning
• Current-loop feedback signal generation for variable frequency drives
• Test benches and simulation environments requiring precise physical signal emulation
• Process engineering systems requiring continuous and synchronized setpoint signals

Installation Guidelines

1. Ensure the system is completely de-energized before mounting or removing the EtherCAT terminal.
2. Mount the terminal on a standard 35 mm DIN rail conforming to EN 60715. Use the integrated locking mechanism and slot-and-key connection for side-by-side terminal mounting.
3. Ensure secure electrical connection via the gold-plated E-bus power contacts. Do not clean contacts with abrasive tools.
4. Strip conductors to a length of 8 to 9 mm. Terminate using solid wire, stranded wire, or wire-end ferrules through the spring actuation mechanism.
5. Perform electrical and functional testing on the signal lines before energizing the control system.

Replacement Recommendations

When replacing an existing terminal with the BECKHOFF EL4114-0020, verify that the 16-bit configuration and mapping match your TwinCAT process image settings, particularly if replacing a standard 12-bit output terminal. Ensure that the individual calibration requirements of your application are verified and documented with the newly supplied factory certificate details.
