Product Description

Description

The BECKHOFF EL3124 is an EtherCAT Terminal featuring 4 channels for analog current measurement within the 4 to 20 mA range at a 16-bit resolution. Designed for integration into EtherCAT industrial automation networks, this terminal processes differential input signals to deliver precise process data acquisition for machine and plant control applications.

Housed in a compact terminal block, the device supports distributed clocks for time-synchronous data acquisition and includes activatable FIR and IIR filters alongside built-in limit value monitoring. Power for the internal electronics is supplied via the E-bus, while signal connections utilize spring-loaded wiring technology for secure conductor retention.

Features

Four differential analog input channels supporting 4 to 20 mA current signals
16-bit resolution including sign for high-precision measurement
Distributed clocks support for time-synchronized data acquisition across the network
Activatable FIR and IIR filters for adjustable signal conditioning
Integrated limit value monitoring for threshold detection
Selectable standard and compact process image configurations
Power supply routed via the E-bus with no external terminal supply required for internal logic

Applications

Industrial analog sensor interfacing and process variable monitoring
Precision current loop data acquisition in machine automation systems
Synchronized multi-channel measurement setups requiring distributed clocks

Installation Guidelines

Ensure all system power and field supplies are switched off and locked out before performing any mechanical or electrical work.
Inspect the terminal housing and spring contacts for signs of transit damage or contamination.
Mount the terminal onto a 35 mm DIN rail (EN 60715) by snapping it securely into place alongside existing EtherCAT terminals using the double slot and key connection.
Connect field sensors to the appropriate terminal connection points using solid, stranded, or ferruled conductors stripped to 8 to 9 mm. Use a suitable screwdriver to operate the spring mechanism.
Verify that the E-bus connections engage correctly with neighboring devices to ensure data communication and internal logic power continuity.
Restore power supplies only after verifying all wiring integrity, signal polarities, and network connections.
