Description

Designed for high-precision industrial control processes, the BECKHOFF EL4122 is a 2-channel analog output EtherCAT Terminal operating within the 4 to 20 mA range. This module converts digital control values from the automation system into analog current signals with a high-resolution output of 16 bits. Electrically isolated from the E-bus, the terminal ensures reliable operation in noise-prone automation environments. Integrated distributed clock functionality provides highly accurate synchronization, supporting synchronization precision to less than 1 us, making it suitable for applications requiring strict timing alignments.

Features

Two channels of analog current outputs supporting a 4 to 20 mA signal range.
High-resolution 16-bit digital-to-analog conversion for accurate control.
Supports Distributed Clocks (DC) for precise synchronization down to less than 1 us.
Short-circuit proof design with load limits under 500 Ohm.
Configurable watchdog parameters and customizable user synchronization.
Compact 12 mm housing width maximizing DIN rail space.
Galvanic isolation of 500 V between the E-bus and the process signal levels.

Applications

Proportional valve control and positioning systems.
Variable speed drive speed referencing and modulation.
Process automation loop controllers in oil, gas, and water utilities.
Actuator and physical positioning control loops.
General manufacturing automation requiring precise analog setpoints.

Installation Guidelines

Mounting: Mount horizontally on a standard 35 mm DIN rail (conforming to EN 60715). Ensure the locking mechanism is securely locked in place.
Interconnection: Connect adjacent modules using the double slot and key connection system to ensure continuous E-bus performance.
Grounding: Ensure the DIN rail is connected to a clean, noise-free functional earth terminal to preserve the signal integrity of the analog channels.
Shielding: Use shielded analog cabling and ground the shields near the terminal entry point to minimize electromagnetically induced noise.
