Product Description

Description

The BECKHOFF EL3144 is a 4-channel analog input EtherCAT Terminal designed to acquire and process current signals in the range of 0 to 20 mA. Operating with single-ended technology, this module provides high-resolution 16-bit measurement for demanding industrial control and instrumentation tasks.

As part of the modular BECKHOFF I/O system, the EL3144 integrates into EtherCAT networks, delivering rapid signal conversion with a time of approximately 40 µs. The integration of Distributed Clocks (DC) allows high-precision, synchronized measurement across complex setups, making it ideal for synchronized control applications.

Housed in a compact 12 mm terminal enclosure, the device features 500 V electrical isolation between the E-bus and the signal channels. This isolation protects the control system from electromagnetic interference and electrical noise common in field environments.

Features

Four single-ended analog inputs configured for 0 to 20 mA current loops
High measurement resolution of 16 bits for accurate signal representation
Fast conversion time of approximately 40 µs
Distributed Clocks (DC) support with synchronization precision under 1 µs
Integrated 5 kHz input filter limit frequency to suppress high-frequency noise
Compact 12 mm DIN rail mountable housing with standard status indication LEDs
Electrical isolation of 500 V (E-bus to signal voltage) for improved field reliability

Applications

Process measurement and continuous monitoring systems
Interfacing with industrial current sensors, including flow meters and pressure transmitters
Closed-loop feedback systems in machine automation
High-speed, multi-channel analog data acquisition setups

Installation Guidelines

Ensure the entire automation system and power contacts are fully de-energized before mounting or removing any modules.
Inspect the terminal for physical damage or debris prior to assembly on the mounting rail.
Mount the module onto a standard 35 mm DIN rail (EN 60715), securing the lock mechanism and ensuring standard slot-and-key connection integrity with adjacent units.
Check that E-bus contacts align correctly with adjacent terminals to maintain proper electrical continuity.
Strip field cables to the recommended 8 to 9 mm. Insert conductors into the terminal connections by activating the spring mechanism with a suitable screwdriver.
Properly ground and shield current loop signals to minimize industrial noise influence on the analog measurements.
Re-energize the system and run configuration steps via TwinCAT to map the process image and verify channel functionality.
