Description

Precision measurement tasks require stable, high-resolution data acquisition, which the EL3602-0020 analog input terminal delivers. This high-precision module processes differential voltage signals across parameterizable ranges of -10 to +10 V, -5 to +5 V, -2.5 to +2.5 V, and -1.25 to +1.25 V. Offering an integrated 24-bit resolution (including sign) and 500 V electrical isolation between the E-bus and the signal channels, this EtherCAT terminal ensures minimal noise interference and exceptional signal integrity in demanding industrial setups.

Every unit is factory calibrated, enabling high-accuracy performance without immediate field calibration. Built for the Beckhoff EtherCAT system architecture, the module interfaces seamlessly via the E-bus backplane, supporting versatile PLC and distributed control topologies across heavy industries, automation cells, and advanced test benches.

Features

Two independent differential analog inputs with high-accuracy factory calibration.
Parameterizable input voltage ranges to accommodate diverse sensor types.
Extremely high 24-bit resolution for micro-volt level signal acquisition.
Integrated limit value monitoring and selectable filter settings.
E-bus powered with 190 mA typical current consumption.
Differential technology with an input filter limit frequency of 3 kHz.

Applications

Power generation monitoring and turbine testing
High-precision force, weight, and torque measurement systems
Oil and gas refinery telemetry and process automation
Research and development test benches requiring high-resolution data logging
